Thieves by nature don’t care about rules, and will use any means to take advantage of victims, most often using trickery or hacking: + +- **Trickery.** Means using things like “phishing” attacks to convince a person to enter a banking password into a website that looks like the bank, but isn’t. + +- **Hacking.** Means attacking a system through malformed content that exploits subtle flaws in a browser, or in various browser extensions, such as video decoders. This exploit lets an attacker run code on a device, taking over first a browsing session, and perhaps ultimately the entire device. + +While trickery and hacking are threats faced by every browser, it’s important that we explore how Microsoft Edge addresses these threats and is helping make the web a safer experience. + +### Help against trickery +Web browsers can help defend your employees against trickery by identifying and blocking known tricks, and by using strong security protocols to ensure that they’re talking to the web site they think they’re talking to. + +#### Windows Hello +Phishing scams get people to enter passwords into a fake version of a trusted website, such as a bank. Attempts to identify legitimate websites through the HTTPS lock symbol and the EV Cert green bar have met with only limited success, since attackers are too good at faking legitimate experiences for many people to notice the difference. + +To really address this problem, we need to stop people from entering plain-text passwords into websites. So in Windows 10, we gave you [Windows Hello](http://blogs.windows.com/bloggingwindows/2015/03/17/making-windows-10-more-personal-and-more-secure-with-windows-hello/) technology with asymmetric cryptography that authenticates both the person and the website. + +Microsoft Edge is the first browser to natively support Windows Hello as a more personal, seamless, and secure way to authenticate on the web, powered by an early implementation of the [Web Authentication (formerly FIDO 2.0 Web API) specification](http://w3c.github.io/webauthn/). + +#### Microsoft SmartScreen +Microsoft SmartScreen, used in Windows 10 and both Internet Explorer 11 and Microsoft Edge, helps to defend against phishing by performing reputation checks on visited sites and blocking any sites that are thought to be phishing sites. SmartScreen also helps to defend people against being tricked into installing malicious [socially-engineered software downloads](http://operationstech.about.com/od/glossary/g/Socially-Engineered-Malware.htm and against [drive-by attacks](https://blogs.windows.com/msedgedev/2015/12/16/smartscreen-drive-by-improvements/). Drive-by attacks are malicious web-based attacks that compromise your system by targeting security vulnerabilities in commonly used software, and may be hosted on trusted sites. + +#### Certificate Reputation system +While people trust sites that have encrypted web traffic, that trust can be undermined by malicious sites using improperly obtained or fake certificates to impersonate legitimate sites. To help address this problem, we introduced the [Certificate Reputation system](http://blogs.msdn.com/b/ie/archive/2014/03/10/certificate-reputation-a-novel-approach-for-protecting-users-from-fraudulent-certificates.aspx) last year. This year, we’ve extended the system to let web developers use the [Bing Webmaster Tools](http://www.bing.com/toolbox/webmaster) to report directly to Microsoft to let us know about fake certificates. + +### Help against hacking +While Microsoft Edge has done much to help defend against trickery, the browser’s “engine” has also been overhauled to resist hacking (attempts to corrupt the browser itself) including a major overhaul of the DOM representation in the browser’s memory, and the security mitigations described here. + +#### Microsoft EdgeHTML and modern web standards +Microsoft Edge has a new rendering engine, Microsoft EdgeHTML, which is focused on modern standards that let web developers build and maintain a consistent site across all modern browsers. + +The Microsoft EdgeHTML engine also helps to defend against hacking through these new security standards features: + +- Support for the W3C standard for [Content Security Policy (CSP)](https://developer.microsoft.com/en-us/microsoft-edge/platform/documentation/dev-guide/security/content-Security-Policy), which can help web developers defend their sites against cross-site scripting attacks. + +- Support for the [HTTP Strict Transport Security (HSTS)](https://developer.microsoft.com/en-us/microsoft-edge/platform/documentation/dev-guide/security/HSTS/) security feature (IETF-standard compliant). This helps ensure that connections to important sites, such as to your bank, are always secured. + + **Note**
+ Both Microsoft Edge and Internet Explorer 11 support HSTS. + +#### All web content runs in an app container sandbox +Internet Explorer 7 on Windows Vista was the first web browser to provide a browsing sandbox, called [Protected Mode](http://windows.microsoft.com/en-US/windows-vista/What-does-Internet-Explorer-protected-mode-do). Protected Mode forced the part of the browser that rendered web content to run with less privilege than the browser controls or the user, providing a level of isolation and protection should a malicious website attempt to exploit a bug in the browser or one of its plug-ins. + +Internet Explorer 10 introduced Enhanced Protected Mode (EPM), based on the Windows 8 app container technology, providing a stronger sandbox by adding deny-by-default and no-read-up semantics. EPM was turned on by default in the Windows 8 and Windows 8.1 immersive browser, but was optional on the Internet Explorer 10 and Internet Explorer 11 desktop versions. + +Microsoft Edge takes the sandbox even farther, running its content processes in app containers not just by default, but all of the time. Because Microsoft Edge doesn’t support 3rd party binary extensions, there’s no reason for it to run outside of the containers, ensuring that Microsoft Edge is more secure. + +#### Microsoft Edge is now a 64-bit app +The largest security change to Microsoft Edge is that it's designed like a Universal Windows app. By changing the browser to an app, it fundamentally changes the process model so that both the outer manager process and the assorted content processes all live within app container sandboxes; helping to provide the user and the platform with the [confidence](http://blogs.msdn.com/b/b8/archive/2012/05/17/delivering-reliable-and-trustworthy-metro-style-apps.aspx) provided by other Windows store apps. + +##### 64-bit processes and Address Space Layout Randomization (ASLR) +Microsoft Edge runs in 64-bit not just by default, but anytime it’s running on a 64-bit operating system. Because Microsoft Edge doesn’t support legacy ActiveX controls or 3rd-party binary extensions, there’s no longer a reason to run 32-bit processes on a 64-bit system. + +The value of running 64-bit all the time is that it strengthens Windows Address Space Layout Randomization (ASLR). ASLR randomizes the memory layout of the browser processes, making it much harder for attackers to hit precise memory locations. In turn, 64-bit processes make ASLR much more effective by making the address space exponentially larger and, therefore, more difficult for attackers to find the sensitive memory components they’re looking for. + +#### New extension model and HTML5 support +Back in 1996, we introduced ActiveX for web browser extensions in an attempt to let 3rd parties experiment with various forms of alternate content on the web. However, we quickly learned that browser extensions can come at a cost of security and reliability. For example, binary extensions can bring code and data into the browser’s processes without any protection, meaning that if anything goes wrong, the entire browser itself can be compromised or go down. + +Based on that learning, we’ve stopped supporting binary extensions in Microsoft Edge and instead encourage everyone to use our new, scripted HTML5-based extension model. For more info about the new extensions, see the [Microsoft Edge Developer Center](https://developer.microsoft.com/en-us/microsoft-edge/extensions/). + +#### Reduced attack surfaces +In addition to removing support for VBScript, Jscript, VML, Browser Helper Objects, Toolbars, and ActiveX controls, Microsoft Edge also removed support for legacy Internet Explorer [document modes](https://msdn.microsoft.com/en-us/library/jj676915.aspx). Because many IE browser vulnerabilities are only present in legacy document modes, removing support for document modes significantly reduces attack surface, making the browser much more secure than before. However, it also means that it’s not as backward compatible. + +Because of the reduced backward compatibility, we’ve given Microsoft Edge the ability to automatically fall back to Internet Explorer 11, using the Enterprise Mode Site List, for any apps that need backward compatibility. + +#### Code integrity and image loading restrictions +Microsoft Edge content processes support code integrity and image load restrictions, helping to prevent malicious DLLs from loading or being injected into the content processes. Only [properly signed images](https://blogs.windows.com/msedgedev/2015/11/17/microsoft-edge-module-code-integrity/) are allowed to load into Microsoft Edge. Binaries on remote devices (such as, UNC or WebDAV) can’t be loaded. + +#### Memory corruption mitigations +Memory corruption happens most frequently to apps written in C or C++ because those languages don’t provide type safety or buffer overflow protection. Broadly speaking, memory corruption attacks happen when an attacker provides malformed input to a program and the program can’t handle it, corrupting the program’s memory state and allowing the attacker to take control of the program. + +Over the years, a broad variety of mitigations have been created around memory corruption, but even as these mitigations roll out, attackers adapt and invent new ways to attack. At the same time, we’ve responded with new memory safety defenses, mitigating the most common new forms of attack, including and especially [use-after-free (UAF)](http://cwe.mitre.org/data/definitions/416.html) vulnerabilities. + +##### Memory Garbage Collector (MemGC) mitigation +MemGC is the replacement for Memory Protector, currently turned on for both Microsoft Edge on Windows 10 and Internet Explorer 11 on Windows 7 and newer operating systems. MemGC is a memory garbage collection system that helps to defend the browser from UAF vulnerabilities by taking the responsibility for freeing memory away from the programmer and instead automating it, only freeing memory when the automation detects that there are no more references left pointing to a given block of memory. + +##### Control Flow Guard +Ultimately, attackers use memory corruption attacks to gain control of the CPU program counter so that they can jump to any code location they want. Control Flow Guard is a Microsoft Visual Studio technology that compiles checks around code that performs indirect jumps based on a pointer, restricting those jumps to only go to function entry points with known addresses. This makes attacker take-overs much more difficult by severely constraining where a memory corruption attack can jump to. + +#### Designed for security +We’ve spent countless hours reviewing, testing, and using Microsoft Edge to make sure that you’re more protected than ever before. + +##### Fuzzing/Static Analysis +We’ve devoted more than 670 machine-years to fuzz testing Microsoft Edge and Internet Explorer during product development, including monitoring for possible exceptions such as crashes or memory leaks. We’ve also generated more than 400-billion DOM manipulations from 1-billion HTML files. Because of all of this, hundreds of security issues were addressed before the product shipped. + +##### Code Review & Penetration Testing +Over 70 end-to-end security engagements reviewed all key features, helping to address security implementation and design issues before shipping. + +##### Windows REDTEAM +The Windows REDTEAM emulates the techniques and expertise of skilled, real-world attackers. Exploited Microsoft Edge vulnerabilities discovered through penetration testing can be addressed before public discovery and real-world exploits. + + + + + + + + + + diff --git a/browsers/internet-explorer/TOC.md b/browsers/internet-explorer/TOC.md index 8c1b80824c..440e179791 100644 --- a/browsers/internet-explorer/TOC.md +++ b/browsers/internet-explorer/TOC.md @@ -26,7 +26,7 @@ ###[Enterprise Mode schema v.1 guidance for Windows 7 and Windows 8.1 devices](ie11-deploy-guide/enterprise-mode-schema-version-1-guidance.md) ###[Check for a new Enterprise Mode site list xml file](ie11-deploy-guide/check-for-new-enterprise-mode-site-list-xml-file.md) ###[Turn on local control and logging for Enterprise Mode](ie11-deploy-guide/turn-on-local-control-and-logging-for-enterprise-mode.md) -###[Use the Enterprise Mode Site List Manager tool](ie11-deploy-guide/use-the-enterprise-mode-site-list-manager-tool.md) +###[Use the Enterprise Mode Site List Manager tool](ie11-deploy-guide/use-the-enterprise-mode-site-list-manager.md) ####[Add sites to the Enterprise Mode site list using the Windows 10 Enterprise Mode Site List Manager tool](ie11-deploy-guide/add-single-sites-to-enterprise-mode-site-list-using-the-version-2-enterprise-mode-tool.md) ####[Add sites to the Enterprise Mode site list using the Windows 7 and Windows 8.1 Enterprise Mode Site List Manager tool](ie11-deploy-guide/add-single-sites-to-enterprise-mode-site-list-using-the-version-1-enterprise-mode-tool.md) ####[Add multiple sites to the Enterprise Mode site list using a file and the Windows 10 Enterprise Mode Site List Manager tool](ie11-deploy-guide/add-multiple-sites-to-enterprise-mode-site-list-using-the-version-2-schema-and-enterprise-mode-tool.md) diff --git a/browsers/internet-explorer/ie11-deploy-guide/activex-installation-using-group-policy.md b/browsers/internet-explorer/ie11-deploy-guide/activex-installation-using-group-policy.md index 9066c5205a..76fc4cad35 100644 --- a/browsers/internet-explorer/ie11-deploy-guide/activex-installation-using-group-policy.md +++ b/browsers/internet-explorer/ie11-deploy-guide/activex-installation-using-group-policy.md @@ -2,7 +2,7 @@ description: How to use Group Policy to install ActiveX controls. ms.assetid: 59185370-558c-47e0-930c-8a5ed657e9e3 author: eross-msft -ms.prod: IE11 +ms.prod: ie11 ms.mktglfcycl: deploy ms.sitesec: library ms.pagetype: security diff --git a/browsers/internet-explorer/ie11-deploy-guide/add-multiple-sites-to-enterprise-mode-site-list-using-the-version-1-schema-and-enterprise-mode-tool.md b/browsers/internet-explorer/ie11-deploy-guide/add-multiple-sites-to-enterprise-mode-site-list-using-the-version-1-schema-and-enterprise-mode-tool.md index 1b86656cdc..2a371e334b 100644 --- a/browsers/internet-explorer/ie11-deploy-guide/add-multiple-sites-to-enterprise-mode-site-list-using-the-version-1-schema-and-enterprise-mode-tool.md +++ b/browsers/internet-explorer/ie11-deploy-guide/add-multiple-sites-to-enterprise-mode-site-list-using-the-version-1-schema-and-enterprise-mode-tool.md @@ -1,24 +1,24 @@ --- -description: You can add multiple sites to your Enterprise Mode site list by creating a custom text (TXT) or Extensible Markup Language (XML) file of problematic sites and then adding it in the Bulk add from file area of the Enterprise Mode Site List Manager tool. +description: You can add multiple sites to your Enterprise Mode site list by creating a custom text (TXT) or Extensible Markup Language (XML) file of problematic sites and then adding it in the Bulk add from file area of the Enterprise Mode Site List Manager. ms.assetid: 20aF07c4-051a-451f-9c46-5a052d9Ae27c author: eross-msft -ms.prod: IE11 +ms.prod: ie11 ms.mktglfcycl: deploy ms.sitesec: library ms.pagetype: appcompat -title: Add multiple sites to the Enterprise Mode site list using a file and the Windows 7 and Windows 8.1 Enterprise Mode Site List Manager tool (Internet Explorer 11 for IT Pros) +title: Add multiple sites to the Enterprise Mode site list using a file and the Enterprise Mode Site List Manager (schema v.1) (Internet Explorer 11 for IT Pros) --- -# Add multiple sites to the Enterprise Mode site list using a file and the Windows 7 and Windows 8.1 Enterprise Mode Site List Manager tool +# Add multiple sites to the Enterprise Mode site list using a file and the Enterprise Mode Site List Manager (schema v.1) **Applies to:** - Windows 8.1 - Windows 7 -You can add multiple sites to your Enterprise Mode site list by creating a custom text (TXT) or Extensible Markup Language (XML) file of problematic sites and then adding it in the **Bulk add from file** area of the Enterprise Mode Site List Manager tool.

On the deployment computer, click **Start**, and type **deployment**. + +2. Right-click **Deployment and Imaging Tools Environment** and then click **Run as administrator**. The Deployment and Imaging Tools Environment shortcut opens a Command Prompt window and automatically sets environment variables to point to all the necessary tools. + +3. Run the following command to copy the base Windows PE files into a new folder. The script requires two arguments: hardware architecture and destination location. The value of **<architecture>** can be **x86**, **amd64**, or **arm** and **<destination>** is a path to a local directory. If the directory does not already exist, it will be created. + + ``` + copype.cmd + ``` + + For example, the following command copies **amd64** architecture files to the **C:\winpe_amd64** directory: + + ``` + copype.cmd amd64 C:\winpe_amd64 + ``` + + The script creates the destination directory structure and copies all the necessary files for that architecture. In the previous example, the following directories are created: + + ``` + C:\winpe_amd64 + C:\winpe_amd64\fwfiles + C:\winpe_amd64\media + C:\winpe_amd64\mount + ``` +4. Mount the base Windows PE image (winpe.wim) to the \mount directory using the DISM tool. Mounting an image file unpacks the file contents into a folder so that you can make changes directly or by using tools such as DISM. See the following example. + + ``` + Dism /mount-image /imagefile:c:\winpe_amd64\media\sources\boot.wim /index:1 /mountdir:C:\winpe_amd64\mount + ``` +5. Map a network share to the root TFTP directory on the PXE/TFTP server and create a \Boot folder. Consult your TFTP server documentation to determine the root TFTP server directory, then enable sharing for this directory, and verify it can be accessed on the network. In the following example, the PXE server name is PXE-1 and the TFTP root directory is shared using a network path of **\\\PXE-1\TFTPRoot**: + + ``` + net use y: \\PXE-1\TFTPRoot + y: + md boot + ``` +6. Copy the PXE boot files from the mounted directory to the \Boot folder. For example: + + ``` + copy c:\winpe_amd64\mount\windows\boot\pxe\*.* y:\boot + ``` +7. Copy the boot.sdi file to the PXE/TFTP server. + + ``` + copy C:\winpe_amd64\media\boot\boot.sdi y:\boot + ``` +8.

A client is directed by DHCP options 066 and 067 to download boot\\wdsnbp.com from the TFTP server. +2. Wdsnbp.com validates the DHCP/PXE response packet and then the client downloads boot\\pxeboot.com. +3. Pxeboot.com requires the client to press the F12 key to initiate a PXE boot. +4. The client downloads boot\\bootmgr.exe and the boot\\BCD file from the TFTP server. Note: The BCD store must reside in the \\boot directory on the TFTP server and must be named BCD. +5. Bootmgr.exe reads the BCD operating system entries and downloads boot\\boot.sdi and the Windows PE image (boot\\boot.wim). Optional files that can also be downloaded include true type fonts (boot\\Fonts\\wgl4\_boot.ttf) and the hibernation state file (\\hiberfil.sys) if these files are present. +6. Bootmgr.exe starts Windows PE by calling winload.exe within the Windows PE image. +7. Windows PE loads, a command prompt opens and wpeinit.exe is run to initialize Windows PE. +8. The Windows PE client provides access to tools like imagex, diskpart, and bcdboot using the Windows PE command prompt.

An SA is a combination of a mutually agreeable policy and keys that define the security services and mechanisms that help protect communication between IPsec peers. -AuthIP is an enhanced version of IKE that offers additional flexibility with support for user-based authentication, authentication with multiple credentials, improved authentication method negotiation, and asymmetric authentication. Like IKE, AuthIP supports Main Mode and Quick Mode negotiation. -Quick Mode (also known as Phase 2) IKE negotiation establishes a secure channel between two computers to protect data. Because this phase involves the establishment of security associations (SAs) that are negotiated on behalf of the IPsec service, the SAs that are created during Quick Mode are called the IPsec SAs. During Quick Mode, keying material is refreshed or, if necessary, new keys are generated. A protection suite that protects specified IP traffic is also selected. A protection suite is a defined set of data integrity or data encryption settings. Quick Mode is not considered a complete exchange because it is dependent on a Main Mode exchange. +Audit IPsec Quick Mode allows you to audit events generated by Internet Key Exchange protocol (IKE) and Authenticated Internet Protocol (AuthIP) during Quick Mode negotiations. -Event volume: High +Audit IPsec Quick Mode subcategory is out of scope of this document, because this subcategory is mainly used for IPsec Quick Mode troubleshooting. -Default: Not configured +| Computer Type | General Success | General Failure | Stronger Success | Stronger Failure | Comments | +|-------------------|-----------------|-----------------|------------------|------------------|--------------------------------------------------------------------------------------------------------------------------------------| +| Domain Controller | IF | IF | IF | IF | IF - This subcategory is mainly used for IPsec Quick Mode troubleshooting, or for tracing or monitoring IPsec Quick Mode operations. | +| Member Server | IF | IF | IF | IF | IF - This subcategory is mainly used for IPsec Quick Mode troubleshooting, or for tracing or monitoring IPsec Quick Mode operations. | +| Workstation | IF | IF | IF | IF | IF - This subcategory is mainly used for IPsec Quick Mode troubleshooting, or for tracing or monitoring IPsec Quick Mode operations. | -| Event ID | Event message | -|- |- | -| 4977 | During Quick Mode negotiation, IPsec received an invalid negotiation packet.

You can track, for example, actions with files or folders on USB flash drives or sticks that were inserted into domain controllers or high value servers, which is typically not allowed.

This rule would instruct the front-end servers to accept traffic from the non-Windows device even though it cannot authenticate. + +A more secure solution, and the one selected by Woodgrove Bank, is to include the non-Windows device in the domain isolation design. Because it cannot join an Active Directory domain, Woodgrove Bank chose to use certificate-based authentication. Certificates are cryptographically-protected documents, encrypted in such a way that their origin can be positively confirmed. + +In this case, Woodgrove Bank used Active Directory Certificate Services to create the appropriate certificate. They might also have acquired and installed a certificate from a third-party commercial certification authority. They then used Group Policy to deploy the certificate to the front-end servers. The GPOs applied to the front-end servers also include updated connection security rules that permit certificate-based authentication in addition to Kerberos V5 authentication.

The only constraint is that the main mode and quick mode encryption algorithms supported by the UNIX device must also be supported by the Windows-based devices with which it communicates. + +**Other traffic notes:** + +- None of the capabilities of the other designs discussed in this guide are compromised by the use of certificate authentication by a non-Windows device. + +## Design details + +Woodgrove Bank uses Active Directory groups and GPOs to deploy the domain isolation settings and rules to the devices in their organization. + +The inclusion of one or more non-Windows devices to the network requires only a simple addition to the GPOs for devices that must communicate with the non-Windows device. The addition is allowing certificate-based authentication in addition to the Active Directory–supported Kerberos V5 authentication. This does not require including new rules, just adding certificate-based authentication as an option to the existing rules. + +When multiple authentication methods are available, two negotiating devices agree on the first one in their lists that match. Because the majority of the devices in Woodgrove Bank's network run Windows, Kerberos V5 is listed as the first authentication method in the rules. Certificate-based authentication is added as an alternate authentication type. + +By using the Active Directory Users and Computers snap-in, Woodgrove Bank created a group named NAG\_COMPUTER\_WGBUNIX. They then added the device accounts to this group for Windows devices that need to communicate with the non-Windows devices. If all the devices in the isolated domain need to be able to access the non-Windows devices, then the **Domain Computers** group can be added to the group as a member. + +Woodgrove Bank then created a GPO that contains the certificate, and then attached security group filters to the GPO that allow read and apply permissions to only members of the NAG\_COMPUTER\_WGBUNIX group. The GPO places the certificate in the **Local Computer / Personal / Certificates** certificate store. The certificate used must chain back to a certificate that is in the **Trusted Root Certification Authorities** store on the local device. + +**Next: **[Designing a Windows Firewall with Advanced Security Strategy](designing-a-windows-firewall-with-advanced-security-strategy.md) diff --git a/windows/keep-secure/certificate-based-isolation-policy-design.md b/windows/keep-secure/certificate-based-isolation-policy-design.md new file mode 100644 index 0000000000..8d0483f776 --- /dev/null +++ b/windows/keep-secure/certificate-based-isolation-policy-design.md @@ -0,0 +1,40 @@ +--- +title: Certificate-based Isolation Policy Design (Windows 10) +description: Certificate-based Isolation Policy Design +ms.assetid: 63e01a60-9daa-4701-9472-096c85e0f862 +ms.prod: w10 +ms.mktglfcycl: deploy +ms.sitesec: library +ms.pagetype: security +author: brianlic-msft +--- + +# Certificate-based Isolation Policy Design + +**Applies to** +- Windows 10 +- Windows Server 2016 Technical Preview + +In the certificate-based isolation policy design, you provide the same types of protections to your network traffic as described in the [Domain Isolation Policy Design](domain-isolation-policy-design.md) and [Server Isolation Policy Design](server-isolation-policy-design.md) sections.

Because different versions of Windows can support different settings and rules to achieve similar behavior, you might need multiple GPOs: one for each operating system that has settings different from the others to achieve the same result. For example, Windows 10, Windows 8, Windows 7, Windows Vista, Windows Server 2012, Windows Server 2008, and Windows Server 2008 R2 use rules and settings that are incompatible with Windows 2000, Windows XP, and Windows Server 2003. Therefore, if your network included those older operating systems you would need to create a GPO for each set of operating systems that can share common settings. To deploy typical domain isolation settings and rules, you might have five different GPOs for the versions of Windows discussed in this guide. By following the procedures in this guide, you only need one membership group to manage all five GPOs. The membership group is identified in the security group filter for all five GPOs. To apply the settings to a device, you make that device's account a member of the membership group. WMI filters are used to ensure that the correct GPO is applied. + +## About exclusion groups + +A Windows Firewall with Advanced Security design must often take into account domain-joined devices on the network that cannot or must not apply the rules and settings in the GPOs. Because these devices are typically fewer in number than the devices that must apply the GPO, it is easier to use the Domain Members group in the GPO membership group, and then place these exception devices into an exclusion group that is denied Apply Group Policy permissions on the GPO. Because deny permissions take precedence over allow permissions, a device that is a member of both the membership group and the exception group is prevented from applying the GPO. Devices typically found in a GPO exclusion group for domain isolation include the domain controllers, DHCP servers, and DNS servers. + +You can also use a membership group for one zone as an exclusion group for another zone. For example, devices in the boundary and encryption zones are technically in the main domain isolation zone, but must apply only the GPO for their assigned role. To do this, the GPOs for the main isolation zone deny Apply Group Policy permissions to members of the boundary and encryption zones. + +**Checklist: Creating Group Policy objects** + +| Task | Reference | +| - | - | +| Review important concepts and examples for deploying GPOs in a way that best meets the needs of your organization.| [Identifying Your Windows Firewall with Advanced Security Deployment Goals](identifying-your-windows-firewall-with-advanced-security-deployment-goals.md)

Because of that feedback, we're delighted to deliver an enhanced apps policy experience with the June service update. This means that when you open an existing enterprise data protection policy after we release the June service update in your test environment, your existing Windows 10 enterprise data protection app rules (formerly in the **Protected Apps** area) will be removed.

To prepare for this change, we recommend that you make an immediate backup of your current app rules as they are today, so you can use them to help reconfigure your app rules with the enhanced experience. When you open an existing enterprise data protection policy after we release the June service update, you'll get a dialog box telling you about this change.

The term *trusted* can mean different things to different people. Therefore, you must communicate a firm definition for it to all stakeholders in the project. Failure to do this can lead to problems with the security of the trusted environment, because the overall security cannot exceed the level of security set by the least secure client that achieves trusted status. + +>**Note:**  In this context, the term *trust* has nothing to do with an Active Directory trust relationship between domains. The trusted state of your devices just indicates the level of risk that you believe the device brings to the network. Trusted devices bring little risk whereas untrusted devices can potentially bring great risk. + +## Trust states + + +To understand this concept, consider the four basic states that apply to devices in a typical IT infrastructure. These states are (in order of risk, lowest risk first): + +- Trusted + +- Trustworthy + +- Known, untrusted + +- Unknown, untrusted + +The remainder of this section defines these states and how to determine which devices in your organization belong in each state. + +### Trusted state + +Classifying a device as trusted means that the device's security risks are managed, but it does not imply that it is perfectly secure or invulnerable. The responsibility for this managed state falls to the IT and security administrators, in addition to the users who are responsible for the configuration of the device. A trusted device that is poorly managed will likely become a point of weakness for the network. + +When a device is considered trusted, other trusted devices can reasonably assume that the device will not initiate a malicious act. For example, trusted devices can expect that other trusted devices will not run a virus that attacks them, because all trusted devices are required to use mechanisms (such as antivirus software) to mitigate the threat of viruses. + +Spend some time defining the goals and technology requirements that your organization considers appropriate as the minimum configuration for a device to obtain trusted status. + +A possible list of technology requirements might include the following: + +- **Operating system.** A trusted client device should run at least Windows Vista. A trusted server should run at least Windows Server 2008. + +- **Domain membership.** A trusted device will belong to a managed Active Directory domain, which means that the IT department has security management rights and can configure member devices by using Group Policy. + +- **Management client.** All trusted devices must run a specific network management client to allow for centralized management and control of security policies, configurations, and software. Configuration Manager is one such management system with an appropriate client. + +- **Antivirus software.** All trusted devices will run antivirus software that is configured to check for and automatically update the latest virus signature files daily. + +- **File system.** All trusted devices will be configured to use the NTFS file system. + +- **BIOS settings.** All trusted portable devices will be configured to use a BIOS-level password that is under the management of the IT support team. + +- **Password requirements.** Trusted clients must use strong passwords. + +It is important to understand that the trusted state is not constant; it is a transient state that is subject to changing security standards and compliance with those standards. New threats and new defenses emerge constantly. For this reason, the organization's management systems must continually check the trusted devices to ensure ongoing compliance. Additionally, the management systems must be able to issue updates or configuration changes if they are required to help maintain the trusted status. + +A device that continues to meet all these security requirements can be considered trusted. However it is possible that most devices that were identified in the discovery process discussed earlier do not meet these requirements. Therefore, you must identify which devices can be trusted and which ones cannot. To help with this process, you use the intermediate *trustworthy* state. The remainder of this section discusses the different states and their implications. + +### Trustworthy state + +It is useful to identify as soon as possible those devices in your current infrastructure that can achieve a trusted state. A *trustworthy state* can be assigned to indicate that the current device can physically achieve the trusted state with required software and configuration changes. + +For each device that is assigned a trustworthy status, make an accompanying configuration note that states what is required to enable the device to achieve trusted status. This information is especially important to both the project design team (to estimate the costs of adding the device to the solution) and the support staff (to enable them to apply the required configuration). + +Generally, trustworthy devices fall into one of the following two groups: + +- **Configuration required.** The current hardware, operating system, and software enable the device to achieve a trustworthy state. However, additional configuration changes are required. For example, if the organization requires a secure file system before a device can be considered trusted, a device that uses a FAT32-formatted hard disk does not meet this requirement. + +- **Upgrade required.** These devices require upgrades before they can be considered trusted. The following list provides some examples of the type of upgrade these devices might require: + + - **Operating system upgrade required.** If the device's current operating system cannot support the security needs of the organization, an upgrade would be required before the device could achieve a trusted state. + + - **Software required.** A device that is missing a required security application, such as an antivirus scanner or a management client, cannot be considered trusted until these applications are installed and active. + + - **Hardware upgrade required.** In some cases, a device might require a specific hardware upgrade before it can achieve trusted status. This type of device usually needs an operating system upgrade or additional software that forces the required hardware upgrade. For example, security software might require additional hard disk space on the device. + + - **Device replacement required.** This category is reserved for devices that cannot support the security requirements of the solution because their hardware cannot support the minimum acceptable configuration. For example, a device that cannot run a secure operating system because it has an old processor (such as a 100-megahertz \[MHz\] x86-based device). + +Use these groups to assign costs for implementing the solution on the devices that require upgrades. + +### Known, untrusted state + +During the process of categorizing an organization's devices, you will identify some devices that cannot achieve trusted status for specific well-understood and well-defined reasons. These reasons might include the following types: + +- **Financial.** The funding is not available to upgrade the hardware or software for this device. + +- **Political.** The device must remain in an untrusted state because of a political or business situation that does not enable it to comply with the stated minimum security requirements of the organization. It is highly recommended that you contact the business owner or independent software vendor (ISV) for the device to discuss the added value of server and domain isolation. + +- **Functional.** The device must run a nonsecure operating system or must operate in a nonsecure manner to perform its role. For example, the device might be required to run an older operating system because a specific line of business application will only work on that operating system. + +There can be multiple functional reasons for a device to remain in the known untrusted state. The following list includes several examples of functional reasons that can lead to a classification of this state: + +- **Devices that run unsupported versions of Windows.** This includes Windows XP, Windows Millennium Edition, Windows 98, Windows 95, or Windows NT. Devices that run these versions of the Windows operating system cannot be classified as trustworthy because these operating systems do not support the required security infrastructure. For example, although Windows NT does support a basic security infrastructure, it does not support “deny” ACLs on local resources, any way to ensure the confidentiality and integrity of network communications, smart cards for strong authentication, or centralized management of device configurations (although limited central management of user configurations is supported). + +- **Stand-alone devices.** Devices running any version of Windows that are configured as stand-alone devices or as members of a workgroup usually cannot achieve a trustworthy state. Although these devices fully support the minimum required basic security infrastructure, the required security management capabilities are unlikely to be available when the device is not a part of a trusted domain. + +- **Devices in an untrusted domain.** A device that is a member of a domain that is not trusted by an organization's IT department cannot be classified as trusted. An untrusted domain is a domain that cannot provide the required security capabilities to its members. Although the operating systems of devices that are members of this untrusted domain might fully support the minimum required basic security infrastructure, the required security management capabilities cannot be fully guaranteed when devices are not in a trusted domain. + +### Unknown, untrusted state + +The unknown, untrusted state should be considered the default state for all devices. Because devices in this state have a configuration that is unknown, you can assign no trust to them. All planning for devices in this state must assume that the device is an unacceptable risk to the organization. Designers of the solution should strive to minimize the impact that the devices in this state can have on their organizations. + +## Capturing upgrade costs for current devices + + +The final step in this part of the process is to record the approximate cost of upgrading the devices to a point that they can participate in the server and domain isolation design. You must make several key decisions during the design phase of the project that require answers to the following questions: + +- Does the device meet the minimum hardware requirements necessary for isolation? + +- Does the device meet the minimum software requirements necessary for isolation? + +- What configuration changes must be made to integrate this device into the isolation solution? + +- What is the projected cost or impact of making the proposed changes to enable the device to achieve a trusted state? + +By answering these questions, you can quickly determine the level of effort and approximate cost of bringing a particular device or group of devices into the scope of the project. It is important to remember that the state of a device is transitive, and that by performing the listed remedial actions you can change the state of a device from untrusted to trusted. After you decide whether to place a device in a trusted state, you are ready to begin planning and designing the isolation groups, which the next section [Planning Domain Isolation Zones](planning-domain-isolation-zones.md) discusses. + +The following table is an example of a data sheet that you could use to help capture the current state of a device and what would be required for the device to achieve a trusted state. + +| Device name | Hardware reqs met | Software reqs met | Configuration required | Details | Projected cost | +| - | - | - | - | - | - | +| CLIENT001 | No| No| Upgrade hardware and software.| Current operating system is Windows XP.

However, it could be considered trustworthy if the required upgrades are possible. However, if many devices require the same upgrades, the overall cost of the solution would be much higher. + +The device SERVER001 is "trustworthy" because it meets the hardware requirements but its operating system must be upgraded. It also requires antivirus software. The projected cost is the amount of effort that is required to upgrade the operating system and install antivirus software, along with their purchase costs. + +With the other information that you have gathered in this section, this information will be the foundation of the efforts performed later in the [Planning Domain Isolation Zones](planning-domain-isolation-zones.md) section. + +The costs identified in this section only capture the projected cost of the device upgrades.

See that example for an explanation of the basic corporate network infrastructure at Woodgrove Bank with diagrams. + +## Design Requirements + +In addition to the basic protection provided by the firewall rules in the previous design example, you might want to implement domain isolation to provide another layer of security to their networked devices. You can create firewall and connection security rules that use authentication to reduce the risk of communicating with untrusted and potentially hostile devices. + +The following illustration shows the traffic protection needed for this design example. + +![domain isolation policy design](images/wfas-design2example1.gif) + +1. All devices on the Woodgrove Bank corporate network that are Active Directory domain members must authenticate inbound network traffic as coming from another computer that is a member of the domain. Unless otherwise specified in this section, Woodgrove Bank's devices reject all unsolicited inbound network traffic that is not authenticated. If the basic firewall design is also implemented, even authenticated inbound network traffic is dropped unless it matches an inbound firewall rule. + +2. The servers hosting the WGPartner programs must be able to receive unsolicited inbound traffic from devices owned by its partners, which are not members of Woodgrove Bank's domain. + +3. Client devices can initiate non-authenticated outbound communications with devices that are not members of the domain, such as browsing external Web sites. Unsolicited inbound traffic from non-domain members is blocked. + +4. Devices in the encryption zone require that all network traffic inbound and outbound must be encrypted, in addition to the authentication already required by the isolated domain. + +**Other traffic notes:** + +- All of the design requirements described in the [Firewall Policy Design Example](firewall-policy-design-example.md) section are still enforced. + +## Design Details + +Woodgrove Bank uses Active Directory groups and GPOs to deploy the domain isolation settings and rules to the devices on its network. + +Setting up groups as described here ensures that you do not have to know what operating system a computer is running before assigning it to a group. As in the firewall policy design, a combination of WMI filters and security group filters are used to ensure that members of the group receive the GPO appropriate for the version of Windows running on that computer. For some groups, you might have four or even five GPOs. + +The following groups were created by using the Active Directory Users and Computers MMC snap-in, all devices that run Windows were added to the correct groups, and then the appropriate GPO are applied to the group. To include a device in the isolated domain or any one of its subordinate zones, simply add the device's account in the appropriate group. + +- **CG\_DOMISO\_ISOLATEDDOMAIN**. The members of this group participate in the isolated domain. After an initial pilot period, followed by a slowly increasing group membership, the membership of this group was eventually replaced with the entry **Domain Computers** to ensure that all devices in the domain participate by default. The WMI filters ensure that the GPO does not apply to domain controllers. GPOs with connection security rules to enforce domain isolation behavior are linked to the domain container and applied to the devices in this group. Filters ensure that each computer receives the correct GPO for its operating system type. The rules in the domain isolation GPO require Kerberos v5 authentication for inbound network connections, and request (but not require) it for all outbound connections. + +- **CG\_DOMISO\_NO\_IPSEC**. This group is denied read or apply permissions on any of the domain isolation GPOs. Any computer that cannot participate in domain isolation, such as a DHCP server running UNIX, is added to this group. + +- **CG\_DOMISO\_BOUNDARY**. This group contains the computer accounts for all the devices that are part of the boundary group able to receive unsolicited inbound traffic from untrusted devices. Members of the group receive a GPO that configures connection security rules to request (but not require) both inbound and outbound authentication. + +- **CG\_DOMISO\_ENCRYPTION**. This group contains the computer accounts for all the devices that require all inbound and outbound traffic to be both authenticated and encrypted. Members of the group receive a GPO that configures connection security and firewall rules to require both authentication and encryption on all inbound and outbound traffic. + +>**Note:**  If you are designing GPOs for only Windows 8, Windows 7, Windows Vista, Windows Server 2012, Windows Server 2008, and Windows Server 2008 R2, you can design your GPOs in nested groups. For example, you can make the boundary group a member of the isolated domain group, so that it receives the firewall and basic isolated domain settings through that nested membership, with only the changes supplied by the boundary zone GPO. However, devices that are running older versions of Windows can only support a single IPsec policy being active at a time. The policies for each GPO must be complete (and to a great extent redundant with each other), because you cannot layer them as you can in the newer versions of Windows. For simplicity, this guide describes the techniques used to create the independent, non-layered policies. We recommend that you create and periodically run a script that compares the memberships of the groups that must be mutually exclusive and reports any devices that are incorrectly assigned to more than one group. + +**Next: **[Server Isolation Policy Design Example](server-isolation-policy-design-example.md) diff --git a/windows/keep-secure/domain-isolation-policy-design.md b/windows/keep-secure/domain-isolation-policy-design.md new file mode 100644 index 0000000000..da2564242b --- /dev/null +++ b/windows/keep-secure/domain-isolation-policy-design.md @@ -0,0 +1,64 @@ +--- +title: Domain Isolation Policy Design (Windows 10) +description: Domain Isolation Policy Design +ms.assetid: 7475084e-f231-473a-9357-5e1d39861d66 +ms.prod: w10 +ms.mktglfcycl: deploy +ms.sitesec: library +ms.pagetype: security +author: brianlic-msft +--- + +# Domain Isolation Policy Design + +**Applies to** +- Windows 10 +- Windows Server 2016 Technical Preview + +In the domain isolation policy design, you configure the devices on your network to accept only connections coming from devices that are authenticated as members of the same isolated domain. + +This design typically begins with a network configured as described in the [Basic Firewall Policy Design](basic-firewall-policy-design.md) section.

The most common authentication packages are: + + - **NTLM** – NTLM-family Authentication + + - **Kerberos** – Kerberos authentication. + + - **Negotiate** – the Negotiate security package selects between Kerberos and NTLM protocols. Negotiate selects Kerberos unless it cannot be used by one of the systems involved in the authentication or the calling application did not provide sufficient information to use Kerberos. + +- **Transited Services** \[Type = UnicodeString\] \[Kerberos-only\]**:** the list of transmitted services. Transmitted services are populated if the logon was a result of a S4U (Service For User) logon process.

In this case, you can monitor for **Network Information\\Source Network Address** and compare the network address with your list of IP addresses. + + - If a particular version of NTLM is always used in your organization. In this case, you can use this event to monitor **Package Name (NTLM only)**, for example, to find events where **Package Name (NTLM only)** does not equal **NTLM V2**. + + - If NTLM is not used in your organization, or should not be used by a specific account (**New Logon\\Security ID**). In this case, monitor for all events where **Authentication Package** is NTLM. + + - If the **Authentication Package** is NTLM. In this case, monitor for **Key Length** not equal to 128, because all Windows operating systems starting with Windows 2000 support 128-bit Key Length. + +- If you monitor for potentially malicious software, or software that is not authorized to request logon actions, monitor this event for **Process Name**. + +- If you have a trusted logon processes list, monitor for a **Logon Process** that is not from the list. + diff --git a/windows/keep-secure/event-4625.md b/windows/keep-secure/event-4625.md new file mode 100644 index 0000000000..9a040ff053 --- /dev/null +++ b/windows/keep-secure/event-4625.md @@ -0,0 +1,289 @@ +--- +title: 4625(F) An account failed to log on.

With this privilege, the user can initiate a process to replace the default token associated with a started subprocess. | +| SeAuditPrivilege | Generate security audits | With this privilege, the user can add entries to the security log. | +| SeBackupPrivilege | Back up files and directories | - Required to perform backup operations.
With this privilege, the user can bypass file and directory, registry, and other persistent object permissions for the purposes of backing up the system.
This privilege causes the system to grant all read access control to any file, regardless of the [*access control list*](https://msdn.microsoft.com/en-us/library/windows/desktop/ms721532(v=vs.85).aspx#_security_access_control_list_gly) (ACL) specified for the file. Any access request other than read is still evaluated with the ACL. The following access rights are granted if this privilege is held:
READ\_CONTROL
ACCESS\_SYSTEM\_SECURITY
FILE\_GENERIC\_READ
FILE\_TRAVERSE | +| SeChangeNotifyPrivilege | Bypass traverse checking | Required to receive notifications of changes to files or directories. This privilege also causes the system to skip all traversal access checks.
With this privilege, the user can traverse directory trees even though the user may not have permissions on the traversed directory. This privilege does not allow the user to list the contents of a directory, only to traverse directories. | +| SeCreateGlobalPrivilege | Create global objects | Required to create named file mapping objects in the global namespace during Terminal Services sessions. | +| SeCreatePagefilePrivilege | Create a pagefile | With this privilege, the user can create and change the size of a pagefile. | +| SeCreatePermanentPrivilege | Create permanent shared objects | Required to create a permanent object.
This privilege is useful to kernel-mode components that extend the object namespace. Components that are running in kernel mode already have this privilege inherently; it is not necessary to assign them the privilege. | +| SeCreateSymbolicLinkPrivilege | Create symbolic links | Required to create a symbolic link. | +| SeCreateTokenPrivilege | Create a token object | Allows a process to create a token which it can then use to get access to any local resources when the process uses NtCreateToken() or other token-creation APIs.
When a process requires this privilege, we recommend using the LocalSystem account (which already includes the privilege), rather than creating a separate user account and assigning this privilege to it. | +| SeDebugPrivilege | Debug programs | Required to debug and adjust the memory of a process owned by another account.
With this privilege, the user can attach a debugger to any process or to the kernel. Developers who are debugging their own applications do not need this user right. Developers who are debugging new system components need this user right. This user right provides complete access to sensitive and critical operating system components. | +| SeEnableDelegationPrivilege | Enable computer and user accounts to be trusted for delegation | Required to mark user and computer accounts as trusted for delegation.
With this privilege, the user can set the **Trusted for Deleg**ation setting on a user or computer object.
The user or object that is granted this privilege must have write access to the account control flags on the user or computer object. A server process running on a computer (or under a user context) that is trusted for delegation can access resources on another computer using the delegated credentials of a client, as long as the account of the client does not have the **Account cannot be delegated** account control flag set. | +| SeImpersonatePrivilege | Impersonate a client after authentication | With this privilege, the user can impersonate other accounts. | +| SeIncreaseBasePriorityPrivilege | Increase scheduling priority | Required to increase the base priority of a process.
With this privilege, the user can use a process with Write property access to another process to increase the execution priority assigned to the other process. A user with this privilege can change the scheduling priority of a process through the Task Manager user interface. | +| SeIncreaseQuotaPrivilege | Adjust memory quotas for a process | Required to increase the quota assigned to a process.
With this privilege, the user can change the maximum memory that can be consumed by a process. | +| SeIncreaseWorkingSetPrivilege | Increase a process working set | Required to allocate more memory for applications that run in the context of users. | +| SeLoadDriverPrivilege | Load and unload device drivers | Required to load or unload a device driver.
With this privilege, the user can dynamically load and unload device drivers or other code in to kernel mode. This user right does not apply to Plug and Play device drivers. | +| SeLockMemoryPrivilege | Lock pages in memory | Required to lock physical pages in memory.
With this privilege, the user can use a process to keep data in physical memory, which prevents the system from paging the data to virtual memory on disk. Exercising this privilege could significantly affect system performance by decreasing the amount of available random access memory (RAM). | +| SeMachineAccountPrivilege | Add workstations to domain | With this privilege, the user can create a computer account.
This privilege is valid only on domain controllers. | +| SeManageVolumePrivilege | Perform volume maintenance tasks | Required to run maintenance tasks on a volume, such as remote defragmentation. | +| SeProfileSingleProcessPrivilege | Profile single process | Required to gather profiling information for a single process.
With this privilege, the user can use performance monitoring tools to monitor the performance of non-system processes. | +| SeRelabelPrivilege | Modify an object label | Required to modify the mandatory integrity level of an object. | +| SeRemoteShutdownPrivilege | Force shutdown from a remote system | Required to shut down a system using a network request. | +| SeRestorePrivilege | Restore files and directories | Required to perform restore operations. This privilege causes the system to grant all write access control to any file, regardless of the ACL specified for the file. Any access request other than write is still evaluated with the ACL. Additionally, this privilege enables you to set any valid user or group SID as the owner of a file. The following access rights are granted if this privilege is held:
WRITE\_DAC
WRITE\_OWNER
ACCESS\_SYSTEM\_SECURITY
FILE\_GENERIC\_WRITE
FILE\_ADD\_FILE
FILE\_ADD\_SUBDIRECTORY
DELETE
With this privilege, the user can bypass file, directory, registry, and other persistent objects permissions when restoring backed up files and directories and determines which users can set any valid security principal as the owner of an object. | +| SeSecurityPrivilege | Manage auditing and security log | Required to perform a number of security-related functions, such as controlling and viewing audit events in security event log.
With this privilege, the user can specify object access auditing options for individual resources, such as files, Active Directory objects, and registry keys.
A user with this privilege can also view and clear the security log. | +| SeShutdownPrivilege | Shut down the system | Required to shut down a local system. | +| SeSyncAgentPrivilege | Synchronize directory service data | This privilege enables the holder to read all objects and properties in the directory, regardless of the protection on the objects and properties. By default, it is assigned to the Administrator and LocalSystem accounts on domain controllers.
With this privilege, the user can synchronize all directory service data. This is also known as Active Directory synchronization. | +| SeSystemEnvironmentPrivilege | Modify firmware environment values | Required to modify the nonvolatile RAM of systems that use this type of memory to store configuration information. | +| SeSystemProfilePrivilege | Profile system performance | Required to gather profiling information for the entire system.
With this privilege, the user can use performance monitoring tools to monitor the performance of system processes. | +| SeSystemtimePrivilege | Change the system time | Required to modify the system time.
With this privilege, the user can change the time and date on the internal clock of the computer. Users that are assigned this user right can affect the appearance of event logs. If the system time is changed, events that are logged will reflect this new time, not the actual time that the events occurred. | +| SeTakeOwnershipPrivilege | Take ownership of files or other objects | Required to take ownership of an object without being granted discretionary access. This privilege allows the owner value to be set only to those values that the holder may legitimately assign as the owner of an object.
With this privilege, the user can take ownership of any securable object in the system, including Active Directory objects, files and folders, printers, registry keys, processes, and threads. | +| SeTcbPrivilege | Act as part of the operating system | This privilege identifies its holder as part of the trusted computer base.
This user right allows a process to impersonate any user without authentication. The process can therefore gain access to the same local resources as that user. | +| SeTimeZonePrivilege | Change the time zone | Required to adjust the time zone associated with the computer's internal clock. | +| SeTrustedCredManAccessPrivilege | Access Credential Manager as a trusted caller | Required to access Credential Manager as a trusted caller. | +| SeUndockPrivilege | Remove computer from docking station | Required to undock a laptop.
With this privilege, the user can undock a portable computer from its docking station without logging on. | +| SeUnsolicitedInputPrivilege | Not applicable | Required to read unsolicited input from a [*terminal*](https://msdn.microsoft.com/en-us/library/windows/desktop/ms721627(v=vs.85).aspx#_security_terminal_gly) device. | + +- **Restricted SID Count** \[Type = UInt32\]: Number of [restricted SIDs](https://msdn.microsoft.com/en-us/library/windows/desktop/aa446583(v=vs.85).aspx) in the token.

With this privilege, the user can initiate a process to replace the default token associated with a started subprocess. | +| SeAuditPrivilege | Generate security audits | With this privilege, the user can add entries to the security log. | +| SeBackupPrivilege | Back up files and directories | - Required to perform backup operations.
With this privilege, the user can bypass file and directory, registry, and other persistent object permissions for the purposes of backing up the system.
This privilege causes the system to grant all read access control to any file, regardless of the [*access control list*](https://msdn.microsoft.com/en-us/library/windows/desktop/ms721532(v=vs.85).aspx#_security_access_control_list_gly) (ACL) specified for the file. Any access request other than read is still evaluated with the ACL. The following access rights are granted if this privilege is held:
READ\_CONTROL
ACCESS\_SYSTEM\_SECURITY
FILE\_GENERIC\_READ
FILE\_TRAVERSE | +| SeChangeNotifyPrivilege | Bypass traverse checking | Required to receive notifications of changes to files or directories. This privilege also causes the system to skip all traversal access checks.
With this privilege, the user can traverse directory trees even though the user may not have permissions on the traversed directory. This privilege does not allow the user to list the contents of a directory, only to traverse directories. | +| SeCreateGlobalPrivilege | Create global objects | Required to create named file mapping objects in the global namespace during Terminal Services sessions. | +| SeCreatePagefilePrivilege | Create a pagefile | With this privilege, the user can create and change the size of a pagefile. | +| SeCreatePermanentPrivilege | Create permanent shared objects | Required to create a permanent object.
This privilege is useful to kernel-mode components that extend the object namespace. Components that are running in kernel mode already have this privilege inherently; it is not necessary to assign them the privilege. | +| SeCreateSymbolicLinkPrivilege | Create symbolic links | Required to create a symbolic link. | +| SeCreateTokenPrivilege | Create a token object | Allows a process to create a token which it can then use to get access to any local resources when the process uses NtCreateToken() or other token-creation APIs.
When a process requires this privilege, we recommend using the LocalSystem account (which already includes the privilege), rather than creating a separate user account and assigning this privilege to it. | +| SeDebugPrivilege | Debug programs | Required to debug and adjust the memory of a process owned by another account.
With this privilege, the user can attach a debugger to any process or to the kernel. Developers who are debugging their own applications do not need this user right. Developers who are debugging new system components need this user right. This user right provides complete access to sensitive and critical operating system components. | +| SeEnableDelegationPrivilege | Enable computer and user accounts to be trusted for delegation | Required to mark user and computer accounts as trusted for delegation.
With this privilege, the user can set the **Trusted for Deleg**ation setting on a user or computer object.
The user or object that is granted this privilege must have write access to the account control flags on the user or computer object. A server process running on a computer (or under a user context) that is trusted for delegation can access resources on another computer using the delegated credentials of a client, as long as the account of the client does not have the **Account cannot be delegated** account control flag set. | +| SeImpersonatePrivilege | Impersonate a client after authentication | With this privilege, the user can impersonate other accounts. | +| SeIncreaseBasePriorityPrivilege | Increase scheduling priority | Required to increase the base priority of a process.
With this privilege, the user can use a process with Write property access to another process to increase the execution priority assigned to the other process. A user with this privilege can change the scheduling priority of a process through the Task Manager user interface. | +| SeIncreaseQuotaPrivilege | Adjust memory quotas for a process | Required to increase the quota assigned to a process.
With this privilege, the user can change the maximum memory that can be consumed by a process. | +| SeIncreaseWorkingSetPrivilege | Increase a process working set | Required to allocate more memory for applications that run in the context of users. | +| SeLoadDriverPrivilege | Load and unload device drivers | Required to load or unload a device driver.
With this privilege, the user can dynamically load and unload device drivers or other code in to kernel mode. This user right does not apply to Plug and Play device drivers. | +| SeLockMemoryPrivilege | Lock pages in memory | Required to lock physical pages in memory.
With this privilege, the user can use a process to keep data in physical memory, which prevents the system from paging the data to virtual memory on disk. Exercising this privilege could significantly affect system performance by decreasing the amount of available random access memory (RAM). | +| SeMachineAccountPrivilege | Add workstations to domain | With this privilege, the user can create a computer account.
This privilege is valid only on domain controllers. | +| SeManageVolumePrivilege | Perform volume maintenance tasks | Required to run maintenance tasks on a volume, such as remote defragmentation. | +| SeProfileSingleProcessPrivilege | Profile single process | Required to gather profiling information for a single process.
With this privilege, the user can use performance monitoring tools to monitor the performance of non-system processes. | +| SeRelabelPrivilege | Modify an object label | Required to modify the mandatory integrity level of an object. | +| SeRemoteShutdownPrivilege | Force shutdown from a remote system | Required to shut down a system using a network request. | +| SeRestorePrivilege | Restore files and directories | Required to perform restore operations. This privilege causes the system to grant all write access control to any file, regardless of the ACL specified for the file. Any access request other than write is still evaluated with the ACL. Additionally, this privilege enables you to set any valid user or group SID as the owner of a file. The following access rights are granted if this privilege is held:
WRITE\_DAC
WRITE\_OWNER
ACCESS\_SYSTEM\_SECURITY
FILE\_GENERIC\_WRITE
FILE\_ADD\_FILE
FILE\_ADD\_SUBDIRECTORY
DELETE
With this privilege, the user can bypass file, directory, registry, and other persistent objects permissions when restoring backed up files and directories and determines which users can set any valid security principal as the owner of an object. | +| SeSecurityPrivilege | Manage auditing and security log | Required to perform a number of security-related functions, such as controlling and viewing audit events in security event log.
With this privilege, the user can specify object access auditing options for individual resources, such as files, Active Directory objects, and registry keys.
A user with this privilege can also view and clear the security log. | +| SeShutdownPrivilege | Shut down the system | Required to shut down a local system. | +| SeSyncAgentPrivilege | Synchronize directory service data | This privilege enables the holder to read all objects and properties in the directory, regardless of the protection on the objects and properties. By default, it is assigned to the Administrator and LocalSystem accounts on domain controllers.
With this privilege, the user can synchronize all directory service data. This is also known as Active Directory synchronization. | +| SeSystemEnvironmentPrivilege | Modify firmware environment values | Required to modify the nonvolatile RAM of systems that use this type of memory to store configuration information. | +| SeSystemProfilePrivilege | Profile system performance | Required to gather profiling information for the entire system.
With this privilege, the user can use performance monitoring tools to monitor the performance of system processes. | +| SeSystemtimePrivilege | Change the system time | Required to modify the system time.
With this privilege, the user can change the time and date on the internal clock of the computer. Users that are assigned this user right can affect the appearance of event logs. If the system time is changed, events that are logged will reflect this new time, not the actual time that the events occurred. | +| SeTakeOwnershipPrivilege | Take ownership of files or other objects | Required to take ownership of an object without being granted discretionary access. This privilege allows the owner value to be set only to those values that the holder may legitimately assign as the owner of an object.
With this privilege, the user can take ownership of any securable object in the system, including Active Directory objects, files and folders, printers, registry keys, processes, and threads. | +| SeTcbPrivilege | Act as part of the operating system | This privilege identifies its holder as part of the trusted computer base.
This user right allows a process to impersonate any user without authentication. The process can therefore gain access to the same local resources as that user. | +| SeTimeZonePrivilege | Change the time zone | Required to adjust the time zone associated with the computer's internal clock. | +| SeTrustedCredManAccessPrivilege | Access Credential Manager as a trusted caller | Required to access Credential Manager as a trusted caller. | +| SeUndockPrivilege | Remove computer from docking station | Required to undock a laptop.
With this privilege, the user can undock a portable computer from its docking station without logging on. | +| SeUnsolicitedInputPrivilege | Not applicable | Required to read unsolicited input from a [*terminal*](https://msdn.microsoft.com/en-us/library/windows/desktop/ms721627(v=vs.85).aspx#_security_terminal_gly) device. | + +- **Properties** \[Type = UnicodeString\]: depends on **Object Type**.

With this privilege, the user can initiate a process to replace the default token associated with a started subprocess. | +| SeAuditPrivilege | Generate security audits | With this privilege, the user can add entries to the security log. | +| SeBackupPrivilege | Back up files and directories | - Required to perform backup operations.
With this privilege, the user can bypass file and directory, registry, and other persistent object permissions for the purposes of backing up the system.
This privilege causes the system to grant all read access control to any file, regardless of the [*access control list*](https://msdn.microsoft.com/en-us/library/windows/desktop/ms721532(v=vs.85).aspx#_security_access_control_list_gly) (ACL) specified for the file. Any access request other than read is still evaluated with the ACL. The following access rights are granted if this privilege is held:
READ\_CONTROL
ACCESS\_SYSTEM\_SECURITY
FILE\_GENERIC\_READ
FILE\_TRAVERSE | +| SeCreateTokenPrivilege | Create a token object | Allows a process to create a token which it can then use to get access to any local resources when the process uses NtCreateToken() or other token-creation APIs.
When a process requires this privilege, we recommend using the LocalSystem account (which already includes the privilege), rather than creating a separate user account and assigning this privilege to it. | +| SeDebugPrivilege | Debug programs | Required to debug and adjust the memory of a process owned by another account.
With this privilege, the user can attach a debugger to any process or to the kernel. Developers who are debugging their own applications do not need this user right. Developers who are debugging new system components need this user right. This user right provides complete access to sensitive and critical operating system components. | +| SeEnableDelegationPrivilege | Enable computer and user accounts to be trusted for delegation | Required to mark user and computer accounts as trusted for delegation.
With this privilege, the user can set the **Trusted for Deleg**ation setting on a user or computer object.
The user or object that is granted this privilege must have write access to the account control flags on the user or computer object. A server process running on a computer (or under a user context) that is trusted for delegation can access resources on another computer using the delegated credentials of a client, as long as the account of the client does not have the **Account cannot be delegated** account control flag set. | +| SeImpersonatePrivilege | Impersonate a client after authentication | With this privilege, the user can impersonate other accounts. | +| SeLoadDriverPrivilege | Load and unload device drivers | Required to load or unload a device driver.
With this privilege, the user can dynamically load and unload device drivers or other code in to kernel mode. This user right does not apply to Plug and Play device drivers. | +| SeRestorePrivilege | Restore files and directories | Required to perform restore operations. This privilege causes the system to grant all write access control to any file, regardless of the ACL specified for the file. Any access request other than write is still evaluated with the ACL. Additionally, this privilege enables you to set any valid user or group SID as the owner of a file. The following access rights are granted if this privilege is held:
WRITE\_DAC
WRITE\_OWNER
ACCESS\_SYSTEM\_SECURITY
FILE\_GENERIC\_WRITE
FILE\_ADD\_FILE
FILE\_ADD\_SUBDIRECTORY
DELETE
With this privilege, the user can bypass file, directory, registry, and other persistent objects permissions when restoring backed up files and directories and determines which users can set any valid security principal as the owner of an object. | +| SeSecurityPrivilege | Manage auditing and security log | Required to perform a number of security-related functions, such as controlling and viewing audit events in security event log.
With this privilege, the user can specify object access auditing options for individual resources, such as files, Active Directory objects, and registry keys.
A user with this privilege can also view and clear the security log. | +| SeSystemEnvironmentPrivilege | Modify firmware environment values | Required to modify the nonvolatile RAM of systems that use this type of memory to store configuration information. | +| SeTakeOwnershipPrivilege | Take ownership of files or other objects | Required to take ownership of an object without being granted discretionary access. This privilege allows the owner value to be set only to those values that the holder may legitimately assign as the owner of an object.
With this privilege, the user can take ownership of any securable object in the system, including Active Directory objects, files and folders, printers, registry keys, processes, and threads. | +| SeTcbPrivilege | Act as part of the operating system | This privilege identifies its holder as part of the trusted computer base.
This user right allows a process to impersonate any user without authentication. The process can therefore gain access to the same local resources as that user. | + +## Security Monitoring Recommendations + +For 4672(S): Special privileges assigned to new logon. + +> **Important**  For this event, also see [Appendix A: Security monitoring recommendations for many audit events](appendix-a-security-monitoring-recommendations-for-many-audit-events.md). + +- Monitor for this event where “**Subject\\Security ID**” is *not* one of these well-known security principals: LOCAL SYSTEM, NETWORK SERVICE, LOCAL SERVICE, and where “**Subject\\Security ID**” is not an administrative account that is expected to have the listed **Privileges**. + +- If you have a list of specific privileges which should never be granted, or granted only to a few accounts (for example, SeDebugPrivilege), use this event to monitor for those “**Privileges**.” + + + +- If you are required to monitor any of the sensitive privileges in the [Event Description for this event](event-4672.md), search for those specific privileges in the event. + diff --git a/windows/keep-secure/event-4673.md b/windows/keep-secure/event-4673.md new file mode 100644 index 0000000000..5282a6658e --- /dev/null +++ b/windows/keep-secure/event-4673.md @@ -0,0 +1,196 @@ +--- +title: 4673(S, F) A privileged service was called.

User Right Group Policy Name** | **Description** | +|-----------------------------------|----------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| +| Audit Non Sensitive Privilege Use | **SeChangeNotifyPrivilege:
**Bypass traverse checking | Required to receive notifications of changes to files or directories. This privilege also causes the system to skip all traversal access checks.
With this privilege, the user can traverse directory trees even though the user may not have permissions on the traversed directory. This privilege does not allow the user to list the contents of a directory, only to traverse directories. | +| Audit Non Sensitive Privilege Use | **SeCreateGlobalPrivilege:
**Create global objects | Required to create named file mapping objects in the global namespace during Terminal Services sessions. | +| Audit Non Sensitive Privilege Use | **SeCreatePagefilePrivilege:
**Create a pagefile | With this privilege, the user can create and change the size of a pagefile. | +| Audit Non Sensitive Privilege Use | **SeCreatePermanentPrivilege:
**Create permanent shared objects | Required to create a permanent object.
This privilege is useful to kernel-mode components that extend the object namespace. Components that are running in kernel mode already have this privilege inherently; it is not necessary to assign them the privilege. | +| Audit Non Sensitive Privilege Use | **SeCreateSymbolicLinkPrivilege:
**Create symbolic links | Required to create a symbolic link. | +| Audit Non Sensitive Privilege Use | **SeIncreaseBasePriorityPrivilege:
**Increase scheduling priority | Required to increase the base priority of a process.
With this privilege, the user can use a process with Write property access to another process to increase the execution priority assigned to the other process. A user with this privilege can change the scheduling priority of a process through the Task Manager user interface. | +| Audit Non Sensitive Privilege Use | **SeIncreaseQuotaPrivilege:
**Adjust memory quotas for a process | Required to increase the quota assigned to a process.
With this privilege, the user can change the maximum memory that can be consumed by a process. | +| Audit Non Sensitive Privilege Use | **SeIncreaseWorkingSetPrivilege:
**Increase a process working set | Required to allocate more memory for applications that run in the context of users. | +| Audit Non Sensitive Privilege Use | **SeLockMemoryPrivilege:
**Lock pages in memory | Required to lock physical pages in memory.
With this privilege, the user can use a process to keep data in physical memory, which prevents the system from paging the data to virtual memory on disk. Exercising this privilege could significantly affect system performance by decreasing the amount of available random access memory (RAM). | +| Audit Non Sensitive Privilege Use | **SeMachineAccountPrivilege:
**Add workstations to domain | With this privilege, the user can create a computer account.
This privilege is valid only on domain controllers. | +| Audit Non Sensitive Privilege Use | **SeManageVolumePrivilege:
**Perform volume maintenance tasks | Required to run maintenance tasks on a volume, such as remote defragmentation. | +| Audit Non Sensitive Privilege Use | **SeProfileSingleProcessPrivilege:
**Profile single process | Required to gather profiling information for a single process.
With this privilege, the user can use performance monitoring tools to monitor the performance of non-system processes. | +| Audit Non Sensitive Privilege Use | **SeRelabelPrivilege:
**Modify an object label | Required to modify the mandatory integrity level of an object. | +| Audit Non Sensitive Privilege Use | **SeRemoteShutdownPrivilege:
**Force shutdown from a remote system | Required to shut down a system using a network request. | +| Audit Non Sensitive Privilege Use | **SeShutdownPrivilege:
**Shut down the system | Required to shut down a local system. | +| Audit Non Sensitive Privilege Use | **SeSyncAgentPrivilege:
**Synchronize directory service data | This privilege enables the holder to read all objects and properties in the directory, regardless of the protection on the objects and properties. By default, it is assigned to the Administrator and LocalSystem accounts on domain controllers.
With this privilege, the user can synchronize all directory service data. This is also known as Active Directory synchronization. | +| Audit Non Sensitive Privilege Use | **SeSystemProfilePrivilege:

With this privilege, the user can initiate a process to replace the default token associated with a started subprocess. | +| SeAuditPrivilege | Generate security audits | With this privilege, the user can add entries to the security log. | +| SeBackupPrivilege | Back up files and directories | - Required to perform backup operations.
With this privilege, the user can bypass file and directory, registry, and other persistent object permissions for the purposes of backing up the system.
This privilege causes the system to grant all read access control to any file, regardless of the [*access control list*](https://msdn.microsoft.com/en-us/library/windows/desktop/ms721532(v=vs.85).aspx#_security_access_control_list_gly) (ACL) specified for the file. Any access request other than read is still evaluated with the ACL. The following access rights are granted if this privilege is held:
READ\_CONTROL
ACCESS\_SYSTEM\_SECURITY
FILE\_GENERIC\_READ
FILE\_TRAVERSE | +| SeChangeNotifyPrivilege | Bypass traverse checking | Required to receive notifications of changes to files or directories. This privilege also causes the system to skip all traversal access checks.
With this privilege, the user can traverse directory trees even though the user may not have permissions on the traversed directory. This privilege does not allow the user to list the contents of a directory, only to traverse directories. | +| SeCreateGlobalPrivilege | Create global objects | Required to create named file mapping objects in the global namespace during Terminal Services sessions. | +| SeCreatePagefilePrivilege | Create a pagefile | With this privilege, the user can create and change the size of a pagefile. | +| SeCreatePermanentPrivilege | Create permanent shared objects | Required to create a permanent object.
This privilege is useful to kernel-mode components that extend the object namespace. Components that are running in kernel mode already have this privilege inherently; it is not necessary to assign them the privilege. | +| SeCreateSymbolicLinkPrivilege | Create symbolic links | Required to create a symbolic link. | +| SeCreateTokenPrivilege | Create a token object | Allows a process to create a token which it can then use to get access to any local resources when the process uses NtCreateToken() or other token-creation APIs.
When a process requires this privilege, we recommend using the LocalSystem account (which already includes the privilege), rather than creating a separate user account and assigning this privilege to it. | +| SeDebugPrivilege | Debug programs | Required to debug and adjust the memory of a process owned by another account.
With this privilege, the user can attach a debugger to any process or to the kernel. Developers who are debugging their own applications do not need this user right. Developers who are debugging new system components need this user right. This user right provides complete access to sensitive and critical operating system components. | +| SeEnableDelegationPrivilege | Enable computer and user accounts to be trusted for delegation | Required to mark user and computer accounts as trusted for delegation.
With this privilege, the user can set the **Trusted for Deleg**ation setting on a user or computer object.
The user or object that is granted this privilege must have write access to the account control flags on the user or computer object. A server process running on a computer (or under a user context) that is trusted for delegation can access resources on another computer using the delegated credentials of a client, as long as the account of the client does not have the **Account cannot be delegated** account control flag set. | +| SeImpersonatePrivilege | Impersonate a client after authentication | With this privilege, the user can impersonate other accounts. | +| SeIncreaseBasePriorityPrivilege | Increase scheduling priority | Required to increase the base priority of a process.
With this privilege, the user can use a process with Write property access to another process to increase the execution priority assigned to the other process. A user with this privilege can change the scheduling priority of a process through the Task Manager user interface. | +| SeIncreaseQuotaPrivilege | Adjust memory quotas for a process | Required to increase the quota assigned to a process.
With this privilege, the user can change the maximum memory that can be consumed by a process. | +| SeIncreaseWorkingSetPrivilege | Increase a process working set | Required to allocate more memory for applications that run in the context of users. | +| SeLoadDriverPrivilege | Load and unload device drivers | Required to load or unload a device driver.
With this privilege, the user can dynamically load and unload device drivers or other code in to kernel mode. This user right does not apply to Plug and Play device drivers. | +| SeLockMemoryPrivilege | Lock pages in memory | Required to lock physical pages in memory.
With this privilege, the user can use a process to keep data in physical memory, which prevents the system from paging the data to virtual memory on disk. Exercising this privilege could significantly affect system performance by decreasing the amount of available random access memory (RAM). | +| SeMachineAccountPrivilege | Add workstations to domain | With this privilege, the user can create a computer account.
This privilege is valid only on domain controllers. | +| SeManageVolumePrivilege | Perform volume maintenance tasks | Required to run maintenance tasks on a volume, such as remote defragmentation. | +| SeProfileSingleProcessPrivilege | Profile single process | Required to gather profiling information for a single process.
With this privilege, the user can use performance monitoring tools to monitor the performance of non-system processes. | +| SeRelabelPrivilege | Modify an object label | Required to modify the mandatory integrity level of an object. | +| SeRemoteShutdownPrivilege | Force shutdown from a remote system | Required to shut down a system using a network request. | +| SeRestorePrivilege | Restore files and directories | Required to perform restore operations. This privilege causes the system to grant all write access control to any file, regardless of the ACL specified for the file. Any access request other than write is still evaluated with the ACL. Additionally, this privilege enables you to set any valid user or group SID as the owner of a file. The following access rights are granted if this privilege is held:
WRITE\_DAC
WRITE\_OWNER
ACCESS\_SYSTEM\_SECURITY
FILE\_GENERIC\_WRITE
FILE\_ADD\_FILE
FILE\_ADD\_SUBDIRECTORY
DELETE
With this privilege, the user can bypass file, directory, registry, and other persistent objects permissions when restoring backed up files and directories and determines which users can set any valid security principal as the owner of an object. | +| SeSecurityPrivilege | Manage auditing and security log | Required to perform a number of security-related functions, such as controlling and viewing audit events in security event log.
With this privilege, the user can specify object access auditing options for individual resources, such as files, Active Directory objects, and registry keys.
A user with this privilege can also view and clear the security log. | +| SeShutdownPrivilege | Shut down the system | Required to shut down a local system. | +| SeSyncAgentPrivilege | Synchronize directory service data | This privilege enables the holder to read all objects and properties in the directory, regardless of the protection on the objects and properties. By default, it is assigned to the Administrator and LocalSystem accounts on domain controllers.
With this privilege, the user can synchronize all directory service data. This is also known as Active Directory synchronization. | +| SeSystemEnvironmentPrivilege | Modify firmware environment values | Required to modify the nonvolatile RAM of systems that use this type of memory to store configuration information. | +| SeSystemProfilePrivilege | Profile system performance | Required to gather profiling information for the entire system.
With this privilege, the user can use performance monitoring tools to monitor the performance of system processes. | +| SeSystemtimePrivilege | Change the system time | Required to modify the system time.
With this privilege, the user can change the time and date on the internal clock of the computer. Users that are assigned this user right can affect the appearance of event logs. If the system time is changed, events that are logged will reflect this new time, not the actual time that the events occurred. | +| SeTakeOwnershipPrivilege | Take ownership of files or other objects | Required to take ownership of an object without being granted discretionary access. This privilege allows the owner value to be set only to those values that the holder may legitimately assign as the owner of an object.
With this privilege, the user can take ownership of any securable object in the system, including Active Directory objects, files and folders, printers, registry keys, processes, and threads. | +| SeTcbPrivilege | Act as part of the operating system | This privilege identifies its holder as part of the trusted computer base.
This user right allows a process to impersonate any user without authentication. The process can therefore gain access to the same local resources as that user. | +| SeTimeZonePrivilege | Change the time zone | Required to adjust the time zone associated with the computer's internal clock. | +| SeTrustedCredManAccessPrivilege | Access Credential Manager as a trusted caller | Required to access Credential Manager as a trusted caller. | +| SeUndockPrivilege | Remove computer from docking station | Required to undock a laptop.
With this privilege, the user can undock a portable computer from its docking station without logging on. | +| SeUnsolicitedInputPrivilege | Not applicable | Required to read unsolicited input from a [*terminal*](https://msdn.microsoft.com/en-us/library/windows/desktop/ms721627(v=vs.85).aspx#_security_terminal_gly) device. | + +**Disabled Privileges** \[Type = UnicodeString\]**:** the list of disabled user rights.

Any access request other than read is still evaluated with the ACL. The following access rights are granted if this privilege is held:
READ\_CONTROL
ACCESS\_SYSTEM\_SECURITY
FILE\_GENERIC\_READ
FILE\_TRAVERSE | +| SeChangeNotifyPrivilege | Bypass traverse checking | Required to receive notifications of changes to files or directories. This privilege also causes the system to skip all traversal access checks.
With this privilege, the user can traverse directory trees even though the user may not have permissions on the traversed directory. This privilege does not allow the user to list the contents of a directory, only to traverse directories. | +| SeCreateGlobalPrivilege | Create global objects | Required to create named file mapping objects in the global namespace during Terminal Services sessions. | +| SeCreatePagefilePrivilege | Create a pagefile | With this privilege, the user can create and change the size of a pagefile. | +| SeCreatePermanentPrivilege | Create permanent shared objects | Required to create a permanent object.
This privilege is useful to kernel-mode components that extend the object namespace. Components that are running in kernel mode already have this privilege inherently; it is not necessary to assign them the privilege. | +| SeCreateSymbolicLinkPrivilege | Create symbolic links | Required to create a symbolic link. | +| SeCreateTokenPrivilege | Create a token object | Allows a process to create a token which it can then use to get access to any local resources when the process uses NtCreateToken() or other token-creation APIs.
When a process requires this privilege, we recommend using the LocalSystem account (which already includes the privilege), rather than creating a separate user account and assigning this privilege to it. | +| SeDebugPrivilege | Debug programs | Required to debug and adjust the memory of a process owned by another account.
With this privilege, the user can attach a debugger to any process or to the kernel. Developers who are debugging their own applications do not need this user right. Developers who are debugging new system components need this user right. This user right provides complete access to sensitive and critical operating system components. | +| SeEnableDelegationPrivilege | Enable computer and user accounts to be trusted for delegation | Required to mark user and computer accounts as trusted for delegation.
With this privilege, the user can set the **Trusted for Deleg**ation setting on a user or computer object.
The user or object that is granted this privilege must have write access to the account control flags on the user or computer object. A server process running on a computer (or under a user context) that is trusted for delegation can access resources on another computer using the delegated credentials of a client, as long as the account of the client does not have the **Account cannot be delegated** account control flag set. | +| SeImpersonatePrivilege | Impersonate a client after authentication | With this privilege, the user can impersonate other accounts. | +| SeIncreaseBasePriorityPrivilege | Increase scheduling priority | Required to increase the base priority of a process.
With this privilege, the user can use a process with Write property access to another process to increase the execution priority assigned to the other process. A user with this privilege can change the scheduling priority of a process through the Task Manager user interface. | +| SeIncreaseQuotaPrivilege | Adjust memory quotas for a process | Required to increase the quota assigned to a process.
With this privilege, the user can change the maximum memory that can be consumed by a process. | +| SeIncreaseWorkingSetPrivilege | Increase a process working set | Required to allocate more memory for applications that run in the context of users. | +| SeLoadDriverPrivilege | Load and unload device drivers | Required to load or unload a device driver.
With this privilege, the user can dynamically load and unload device drivers or other code in to kernel mode. This user right does not apply to Plug and Play device drivers. | +| SeLockMemoryPrivilege | Lock pages in memory | Required to lock physical pages in memory.
With this privilege, the user can use a process to keep data in physical memory, which prevents the system from paging the data to virtual memory on disk. Exercising this privilege could significantly affect system performance by decreasing the amount of available random access memory (RAM). | +| SeMachineAccountPrivilege | Add workstations to domain | With this privilege, the user can create a computer account.
This privilege is valid only on domain controllers. | +| SeManageVolumePrivilege | Perform volume maintenance tasks | Required to run maintenance tasks on a volume, such as remote defragmentation. | +| SeProfileSingleProcessPrivilege | Profile single process | Required to gather profiling information for a single process.
With this privilege, the user can use performance monitoring tools to monitor the performance of non-system processes. | +| SeRelabelPrivilege | Modify an object label | Required to modify the mandatory integrity level of an object. | +| SeRemoteShutdownPrivilege | Force shutdown from a remote system | Required to shut down a system using a network request. | +| SeRestorePrivilege | Restore files and directories | Required to perform restore operations. This privilege causes the system to grant all write access control to any file, regardless of the ACL specified for the file. Any access request other than write is still evaluated with the ACL. Additionally, this privilege enables you to set any valid user or group SID as the owner of a file. The following access rights are granted if this privilege is held:
WRITE\_DAC
WRITE\_OWNER
ACCESS\_SYSTEM\_SECURITY
FILE\_GENERIC\_WRITE
FILE\_ADD\_FILE
FILE\_ADD\_SUBDIRECTORY
DELETE
With this privilege, the user can bypass file, directory, registry, and other persistent objects permissions when restoring backed up files and directories and determines which users can set any valid security principal as the owner of an object. | +| SeSecurityPrivilege | Manage auditing and security log | Required to perform a number of security-related functions, such as controlling and viewing audit events in security event log.
With this privilege, the user can specify object access auditing options for individual resources, such as files, Active Directory objects, and registry keys.
A user with this privilege can also view and clear the security log. | +| SeShutdownPrivilege | Shut down the system | Required to shut down a local system. | +| SeSyncAgentPrivilege | Synchronize directory service data | This privilege enables the holder to read all objects and properties in the directory, regardless of the protection on the objects and properties. By default, it is assigned to the Administrator and LocalSystem accounts on domain controllers.
With this privilege, the user can synchronize all directory service data. This is also known as Active Directory synchronization. | +| SeSystemEnvironmentPrivilege | Modify firmware environment values | Required to modify the nonvolatile RAM of systems that use this type of memory to store configuration information. | +| SeSystemProfilePrivilege | Profile system performance | Required to gather profiling information for the entire system.
With this privilege, the user can use performance monitoring tools to monitor the performance of system processes. | +| SeSystemtimePrivilege | Change the system time | Required to modify the system time.
With this privilege, the user can change the time and date on the internal clock of the computer. Users that are assigned this user right can affect the appearance of event logs. If the system time is changed, events that are logged will reflect this new time, not the actual time that the events occurred. | +| SeTakeOwnershipPrivilege | Take ownership of files or other objects | Required to take ownership of an object without being granted discretionary access. This privilege allows the owner value to be set only to those values that the holder may legitimately assign as the owner of an object.
With this privilege, the user can take ownership of any securable object in the system, including Active Directory objects, files and folders, printers, registry keys, processes, and threads. | +| SeTcbPrivilege | Act as part of the operating system | This privilege identifies its holder as part of the trusted computer base.
This user right allows a process to impersonate any user without authentication. The process can therefore gain access to the same local resources as that user. | +| SeTimeZonePrivilege | Change the time zone | Required to adjust the time zone associated with the computer's internal clock. | +| SeTrustedCredManAccessPrivilege | Access Credential Manager as a trusted caller | Required to access Credential Manager as a trusted caller. | +| SeUndockPrivilege | Remove computer from docking station | Required to undock a laptop.
With this privilege, the user can undock a portable computer from its docking station without logging on. | +| SeUnsolicitedInputPrivilege | Not applicable | Required to read unsolicited input from a [*terminal*](https://msdn.microsoft.com/en-us/library/windows/desktop/ms721627(v=vs.85).aspx#_security_terminal_gly) device. | + + +## Security Monitoring Recommendations + +For 4704(S): A user right was assigned. + +| **Type of monitoring required** | **Recommendation** | +|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| +| **Actions typically performed by the SYSTEM account**: This event and certain other events should be monitored to see if they are triggered by any account other than SYSTEM. | Because this event is typically triggered by the SYSTEM account, we recommend that you report it whenever **“Subject\\Security ID”** is not SYSTEM. | +| **High-value accounts**: You might have high-value domain or local accounts for which you need to monitor each action.

This parameter contains the value of **accountExpires** attribute of new user object. You can change this attribute by using Active Directory Users and Computers, or through a script, for example. This parameter might not be captured in the event, and in that case appears as “-”. For manually created local and domain user accounts this field typically has value “**<never>**”. + +- **Primary Group ID** \[Type = UnicodeString\]: Relative Identifier (RID) of user’s object primary group. + +> **Note**  **Relative identifier (RID)** is a variable length number that is assigned to objects at creation and becomes part of the object's Security Identifier (SID) that uniquely identifies an account or group within a domain. + +Typically, **Primary Group** field for new user accounts has the following values: + +- 513 (Domain Users. For local accounts this RID means Users) – for domain and local users. + + See this article for more information. This parameter contains the value of **primaryGroupID** attribute of new user object. + + + +- **Allowed To Delegate To** \[Type = UnicodeString\]: the list of SPNs to which this account can present delegated credentials. Can be changed using Active Directory Users and Computers management console in **Delegation** tab of user account, if this account has at least one SPN registered. This parameter contains the value of **AllowedToDelegateTo** attribute of new user object. For local user accounts this field is not applicable and typically has value “**-**“. For new domain user accounts it is typically has value “**-**“. See description of **AllowedToDelegateTo** field for “[4738](event-4738.md)(S): A user account was changed.” event for more details. + +> **Note**  **Service Principal Name (SPN)** is the name by which a client uniquely identifies an instance of a service. If you install multiple instances of a service on computers throughout a forest, each instance must have its own SPN. A given service instance can have multiple SPNs if there are multiple names that clients might use for authentication. For example, an SPN always includes the name of the host computer on which the service instance is running, so a service instance might register an SPN for each name or alias of its host. + +- **Old UAC Value** \[Type = UnicodeString\]: specifies flags that control password, lockout, disable/enable, script, and other behavior for the user account. **Old UAC value** always **“0x0”** for new user accounts. This parameter contains the previous value of **userAccountControl** attribute of user object. + +- **New UAC Value** \[Type = UnicodeString\]: specifies flags that control password, lockout, disable/enable, script, and other behavior for the user account. This parameter contains the value of **userAccountControl** attribute of new user object. + +To decode this value, you can go through the property value definitions in the “Table 7. User’s or Computer’s account UAC flags.” from largest to smallest. Compare each property value to the flags value in the event. If the flags value in the event is greater than or equal to the property value, then the property is "set" and applies to that event. Subtract the property value from the flags value in the event and note that the flag applies and then go on to the next flag. + +Here's an example: Flags value from event: 0x15 + +Decoding: + +• PASSWD\_NOTREQD 0x0020 + +• LOCKOUT 0x0010 + +• HOMEDIR\_REQUIRED 0x0008 + +• (undeclared) 0x0004 + +• ACCOUNTDISABLE 0x0002 + +• SCRIPT 0x0001 + +0x0020 > 0x15, so PASSWD\_NOTREQD does not apply to this event + +0x10 < 0x15, so LOCKOUT applies to this event. 0x15 - 0x10 = 0x5 + +0x4 < 0x5, so the undeclared value is set. We'll pretend it doesn't mean anything. 0x5 - 0x4 = 0x1 + +0x2 > 0x1, so ACCOUNTDISABLE does not apply to this event + +0x1 = 0x1, so SCRIPT applies to this event. 0x1 - 0x1 = 0x0, we're done. + +So this UAC flags value decodes to: LOCKOUT and SCRIPT + +- **User Account Control** \[Type = UnicodeString\]**:** shows the list of changes in **userAccountControl** attribute. You will see a line of text for each change. For new user accounts, when the object for this account was created, the **userAccountControl** value was considered to be **“0x0”**, and then it was changed from **“0x0”** to the real value for the account's **userAccountControl** attribute.

You can change user’s primary group using Active Directory Users and Computers management console in the **Member Of** tab of user object properties. You will see a RID of new primary group as a field value. For example, RID 513 (Domain Users) is a default primary group for users. + +Typical **Primary Group** values for user accounts: + +- 513 (Domain Users. For local accounts this RID means Users) – for domain and local users. + + See this article for more information.

If the SPNs list on **Delegation** tab of a user account was changed, you will see the new SPNs list in **AllowedToDelegateTo** field (note that you will see the new list instead of changes) of this event. This is an example of **AllowedToDelegateTo**: + + - dcom/WIN2012 + + - dcom/WIN2012.contoso.local + + If the value of **msDS-AllowedToDelegateTo** attribute of user object was changed, you will see the new value here. + + The value can be “**<value not set>**”, for example, if delegation was disabled. + + For local accounts, this field is not applicable and always has “-“ value. + +> **Note**  **Service Principal Name (SPN)** is the name by which a client uniquely identifies an instance of a service. If you install multiple instances of a service on computers throughout a forest, each instance must have its own SPN. A given service instance can have multiple SPNs if there are multiple names that clients might use for authentication. For example, an SPN always includes the name of the host computer on which the service instance is running, so a service instance might register an SPN for each name or alias of its host. + +- **Old UAC Value** \[Type = UnicodeString\]: specifies flags that control password, lockout, disable/enable, script, and other behavior for the user account. This parameter contains the previous value of **userAccountControl** attribute of user object. + +- **New UAC Value** \[Type = UnicodeString\]: specifies flags that control password, lockout, disable/enable, script, and other behavior for the user account. If the value of **userAccountControl** attribute of user object was changed, you will see the new value here. + +To decode this value, you can go through the property value definitions in the “Table 7. User’s or Computer’s account UAC flags.” from largest to smallest. Compare each property value to the flags value in the event. If the flags value in the event is greater than or equal to the property value, then the property is "set" and applies to that event. Subtract the property value from the flags value in the event and note that the flag applies and then go on to the next flag. + +Here's an example: Flags value from event: 0x15 + +Decoding: + +• PASSWD\_NOTREQD 0x0020 + +• LOCKOUT 0x0010 + +• HOMEDIR\_REQUIRED 0x0008 + +• (undeclared) 0x0004 + +• ACCOUNTDISABLE 0x0002 + +• SCRIPT 0x0001 + +0x0020 > 0x15, so PASSWD\_NOTREQD does not apply to this event + +0x10 < 0x15, so LOCKOUT applies to this event. 0x15 - 0x10 = 0x5 + +0x4 < 0x5, so the undeclared value is set. We'll pretend it doesn't mean anything. 0x5 - 0x4 = 0x1 + +0x2 > 0x1, so ACCOUNTDISABLE does not apply to this event + +0x1 = 0x1, so SCRIPT applies to this event. 0x1 - 0x1 = 0x0, we're done. + +So this UAC flags value decodes to: LOCKOUT and SCRIPT + +- **User Account Control** \[Type = UnicodeString\]**:** shows the list of changes in **userAccountControl** attribute. You will see a line of text for each change. See possible values in here: “Table 7. User’s or Computer’s account UAC flags.”. In the “User Account Control field text” column, you can see the text that will be displayed in the **User Account Control** field in 4738 event. + +- **User Parameters** \[Type = UnicodeString\]: if you change any setting using Active Directory Users and Computers management console in Dial-in tab of user’s account properties, then you will see **<value changed, but not displayed>** in this field. For local accounts, this field is not applicable and always has “<value not set>“ value. + +- **SID History** \[Type = UnicodeString\]: contains previous SIDs used for the object if the object was moved from another domain. Whenever an object is moved from one domain to another, a new SID is created and becomes the objectSID. The previous SID is added to the **sIDHistory** property. If the value of **sIDHistory** attribute of user object was changed, you will see the new value here. + +- **Logon Hours** \[Type = UnicodeString\]: hours that the account is allowed to logon to the domain. If the value of **logonHours** attribute of user object was changed, you will see the new value here. You can change this attribute by using Active Directory Users and Computers, or through a script, for example. Here is an example of this field: + + Sunday 12:00 AM - 7:00 PM + + Sunday 9:00 PM -Monday 1:00 PM + + Monday 2:00 PM -Tuesday 6:00 PM + + Tuesday 8:00 PM -Wednesday 10:00 AM + + For local accounts this field is not applicable and typically has value “**All**”. + +**Additional Information:** + +- **Privileges** \[Type = UnicodeString\]: the list of user privileges which were used during the operation, for example, SeBackupPrivilege.

With this privilege, the user can initiate a process to replace the default token associated with a started subprocess. | +| SeAuditPrivilege | Generate security audits | With this privilege, the user can add entries to the security log. | +| SeBackupPrivilege | Back up files and directories | - Required to perform backup operations.
With this privilege, the user can bypass file and directory, registry, and other persistent object permissions for the purposes of backing up the system.
This privilege causes the system to grant all read access control to any file, regardless of the [*access control list*](https://msdn.microsoft.com/en-us/library/windows/desktop/ms721532(v=vs.85).aspx#_security_access_control_list_gly) (ACL) specified for the file. Any access request other than read is still evaluated with the ACL. The following access rights are granted if this privilege is held:
READ\_CONTROL
ACCESS\_SYSTEM\_SECURITY
FILE\_GENERIC\_READ
FILE\_TRAVERSE | +| SeChangeNotifyPrivilege | Bypass traverse checking | Required to receive notifications of changes to files or directories. This privilege also causes the system to skip all traversal access checks.
With this privilege, the user can traverse directory trees even though the user may not have permissions on the traversed directory. This privilege does not allow the user to list the contents of a directory, only to traverse directories. | +| SeCreateGlobalPrivilege | Create global objects | Required to create named file mapping objects in the global namespace during Terminal Services sessions. | +| SeCreatePagefilePrivilege | Create a pagefile | With this privilege, the user can create and change the size of a pagefile. | +| SeCreatePermanentPrivilege | Create permanent shared objects | Required to create a permanent object.
This privilege is useful to kernel-mode components that extend the object namespace. Components that are running in kernel mode already have this privilege inherently; it is not necessary to assign them the privilege. | +| SeCreateSymbolicLinkPrivilege | Create symbolic links | Required to create a symbolic link. | +| SeCreateTokenPrivilege | Create a token object | Allows a process to create a token which it can then use to get access to any local resources when the process uses NtCreateToken() or other token-creation APIs.
When a process requires this privilege, we recommend using the LocalSystem account (which already includes the privilege), rather than creating a separate user account and assigning this privilege to it. | +| SeDebugPrivilege | Debug programs | Required to debug and adjust the memory of a process owned by another account.
With this privilege, the user can attach a debugger to any process or to the kernel. Developers who are debugging their own applications do not need this user right. Developers who are debugging new system components need this user right. This user right provides complete access to sensitive and critical operating system components. | +| SeEnableDelegationPrivilege | Enable computer and user accounts to be trusted for delegation | Required to mark user and computer accounts as trusted for delegation.
With this privilege, the user can set the **Trusted for Deleg**ation setting on a user or computer object.
The user or object that is granted this privilege must have write access to the account control flags on the user or computer object. A server process running on a computer (or under a user context) that is trusted for delegation can access resources on another computer using the delegated credentials of a client, as long as the account of the client does not have the **Account cannot be delegated** account control flag set. | +| SeImpersonatePrivilege | Impersonate a client after authentication | With this privilege, the user can impersonate other accounts. | +| SeIncreaseBasePriorityPrivilege | Increase scheduling priority | Required to increase the base priority of a process.
With this privilege, the user can use a process with Write property access to another process to increase the execution priority assigned to the other process. A user with this privilege can change the scheduling priority of a process through the Task Manager user interface. | +| SeIncreaseQuotaPrivilege | Adjust memory quotas for a process | Required to increase the quota assigned to a process.
With this privilege, the user can change the maximum memory that can be consumed by a process. | +| SeIncreaseWorkingSetPrivilege | Increase a process working set | Required to allocate more memory for applications that run in the context of users. | +| SeLoadDriverPrivilege | Load and unload device drivers | Required to load or unload a device driver.
With this privilege, the user can dynamically load and unload device drivers or other code in to kernel mode. This user right does not apply to Plug and Play device drivers. | +| SeLockMemoryPrivilege | Lock pages in memory | Required to lock physical pages in memory.
With this privilege, the user can use a process to keep data in physical memory, which prevents the system from paging the data to virtual memory on disk. Exercising this privilege could significantly affect system performance by decreasing the amount of available random access memory (RAM). | +| SeMachineAccountPrivilege | Add workstations to domain | With this privilege, the user can create a computer account.
This privilege is valid only on domain controllers. | +| SeManageVolumePrivilege | Perform volume maintenance tasks | Required to run maintenance tasks on a volume, such as remote defragmentation. | +| SeProfileSingleProcessPrivilege | Profile single process | Required to gather profiling information for a single process.
With this privilege, the user can use performance monitoring tools to monitor the performance of non-system processes. | +| SeRelabelPrivilege | Modify an object label | Required to modify the mandatory integrity level of an object. | +| SeRemoteShutdownPrivilege | Force shutdown from a remote system | Required to shut down a system using a network request. | +| SeRestorePrivilege | Restore files and directories | Required to perform restore operations. This privilege causes the system to grant all write access control to any file, regardless of the ACL specified for the file. Any access request other than write is still evaluated with the ACL. Additionally, this privilege enables you to set any valid user or group SID as the owner of a file. The following access rights are granted if this privilege is held:
WRITE\_DAC
WRITE\_OWNER
ACCESS\_SYSTEM\_SECURITY
FILE\_GENERIC\_WRITE
FILE\_ADD\_FILE
FILE\_ADD\_SUBDIRECTORY
DELETE
With this privilege, the user can bypass file, directory, registry, and other persistent objects permissions when restoring backed up files and directories and determines which users can set any valid security principal as the owner of an object. | +| SeSecurityPrivilege | Manage auditing and security log | Required to perform a number of security-related functions, such as controlling and viewing audit events in security event log.
With this privilege, the user can specify object access auditing options for individual resources, such as files, Active Directory objects, and registry keys.
A user with this privilege can also view and clear the security log. | +| SeShutdownPrivilege | Shut down the system | Required to shut down a local system. | +| SeSyncAgentPrivilege | Synchronize directory service data | This privilege enables the holder to read all objects and properties in the directory, regardless of the protection on the objects and properties. By default, it is assigned to the Administrator and LocalSystem accounts on domain controllers.
With this privilege, the user can synchronize all directory service data. This is also known as Active Directory synchronization. | +| SeSystemEnvironmentPrivilege | Modify firmware environment values | Required to modify the nonvolatile RAM of systems that use this type of memory to store configuration information. | +| SeSystemProfilePrivilege | Profile system performance | Required to gather profiling information for the entire system.
With this privilege, the user can use performance monitoring tools to monitor the performance of system processes. | +| SeSystemtimePrivilege | Change the system time | Required to modify the system time.
With this privilege, the user can change the time and date on the internal clock of the computer. Users that are assigned this user right can affect the appearance of event logs. If the system time is changed, events that are logged will reflect this new time, not the actual time that the events occurred. | +| SeTakeOwnershipPrivilege | Take ownership of files or other objects | Required to take ownership of an object without being granted discretionary access. This privilege allows the owner value to be set only to those values that the holder may legitimately assign as the owner of an object.
With this privilege, the user can take ownership of any securable object in the system, including Active Directory objects, files and folders, printers, registry keys, processes, and threads. | +| SeTcbPrivilege | Act as part of the operating system | This privilege identifies its holder as part of the trusted computer base.
This user right allows a process to impersonate any user without authentication. The process can therefore gain access to the same local resources as that user. | +| SeTimeZonePrivilege | Change the time zone | Required to adjust the time zone associated with the computer's internal clock. | +| SeTrustedCredManAccessPrivilege | Access Credential Manager as a trusted caller | Required to access Credential Manager as a trusted caller. | +| SeUndockPrivilege | Remove computer from docking station | Required to undock a laptop.
With this privilege, the user can undock a portable computer from its docking station without logging on. | +| SeUnsolicitedInputPrivilege | Not applicable | Required to read unsolicited input from a [*terminal*](https://msdn.microsoft.com/en-us/library/windows/desktop/ms721627(v=vs.85).aspx#_security_terminal_gly) device. | + +## Security Monitoring Recommendations + +For 4739(S): Domain Policy was changed. + +- Any settings changes to “**Account Lockout Policy**”, “**Password Policy**”, or “**Network security: Force logoff when logon hours expire**”, plus any **domain functional level and attributes** changes that are reported by this event, must be monitored and an alert should be triggered.

This privilege does not allow the user to list the contents of a directory, only to traverse directories. | +| SeCreateGlobalPrivilege | Create global objects | Required to create named file mapping objects in the global namespace during Terminal Services sessions. | +| SeCreatePagefilePrivilege | Create a pagefile | With this privilege, the user can create and change the size of a pagefile. | +| SeCreatePermanentPrivilege | Create permanent shared objects | Required to create a permanent object.
This privilege is useful to kernel-mode components that extend the object namespace. Components that are running in kernel mode already have this privilege inherently; it is not necessary to assign them the privilege. | +| SeCreateSymbolicLinkPrivilege | Create symbolic links | Required to create a symbolic link. | +| SeCreateTokenPrivilege | Create a token object | Allows a process to create a token which it can then use to get access to any local resources when the process uses NtCreateToken() or other token-creation APIs.
When a process requires this privilege, we recommend using the LocalSystem account (which already includes the privilege), rather than creating a separate user account and assigning this privilege to it. | +| SeDebugPrivilege | Debug programs | Required to debug and adjust the memory of a process owned by another account.
With this privilege, the user can attach a debugger to any process or to the kernel. Developers who are debugging their own applications do not need this user right. Developers who are debugging new system components need this user right. This user right provides complete access to sensitive and critical operating system components. | +| SeEnableDelegationPrivilege | Enable computer and user accounts to be trusted for delegation | Required to mark user and computer accounts as trusted for delegation.
With this privilege, the user can set the **Trusted for Delegation** setting on a user or computer object.
The user or object that is granted this privilege must have write access to the account control flags on the user or computer object. A server process running on a computer (or under a user context) that is trusted for delegation can access resources on another computer using the delegated credentials of a client, as long as the account of the client does not have the **Account cannot be delegated** account control flag set. | +| SeImpersonatePrivilege | Impersonate a client after authentication | With this privilege, the user can impersonate other accounts. | +| SeIncreaseBasePriorityPrivilege | Increase scheduling priority | Required to increase the base priority of a process.

This privilege causes the system to grant all write access control to any file, regardless of the ACL specified for the file. Any access request other than write is still evaluated with the ACL. Additionally, this privilege enables you to set any valid user or group SID as the owner of a file. The following access rights are granted if this privilege is held:
WRITE\_DAC
WRITE\_OWNER
ACCESS\_SYSTEM\_SECURITY
FILE\_GENERIC\_WRITE
FILE\_ADD\_FILE
FILE\_ADD\_SUBDIRECTORY
DELETE
With this privilege, the user can bypass file, directory, registry, and other persistent objects permissions when restoring backed up files and directories and determines which users can set any valid security principal as the owner of an object. | +| SeSecurityPrivilege | Manage auditing and security log | Required to perform a number of security-related functions, such as controlling and viewing audit events in security event log.
With this privilege, the user can specify object access auditing options for individual resources, such as files, Active Directory objects, and registry keys.
A user with this privilege can also view and clear the security log. | +| SeShutdownPrivilege | Shut down the system | Required to shut down a local system. | +| SeSyncAgentPrivilege | Synchronize directory service data | This privilege enables the holder to read all objects and properties in the directory, regardless of the protection on the objects and properties. By default, it is assigned to the Administrator and LocalSystem accounts on domain controllers.
With this privilege, the user can synchronize all directory service data. This is also known as Active Directory synchronization. | +| SeSystemEnvironmentPrivilege | Modify firmware environment values | Required to modify the nonvolatile RAM of systems that use this type of memory to store configuration information. | +| SeSystemProfilePrivilege | Profile system performance | Required to gather profiling information for the entire system.
With this privilege, the user can use performance monitoring tools to monitor the performance of system processes. | +| SeSystemtimePrivilege | Change the system time | Required to modify the system time.
With this privilege, the user can change the time and date on the internal clock of the computer. Users that are assigned this user right can affect the appearance of event logs. If the system time is changed, events that are logged will reflect this new time, not the actual time that the events occurred. | +| SeTakeOwnershipPrivilege | Take ownership of files or other objects | Required to take ownership of an object without being granted discretionary access. This privilege allows the owner value to be set only to those values that the holder may legitimately assign as the owner of an object.
With this privilege, the user can take ownership of any securable object in the system, including Active Directory objects, files and folders, printers, registry keys, processes, and threads. | +| SeTcbPrivilege | Act as part of the operating system | This privilege identifies its holder as part of the trusted computer base.
This user right allows a process to impersonate any user without authentication. The process can therefore gain access to the same local resources as that user. | +| SeTimeZonePrivilege | Change the time zone | Required to adjust the time zone associated with the computer's internal clock. | +| SeTrustedCredManAccessPrivilege | Access Credential Manager as a trusted caller | Required to access Credential Manager as a trusted caller. | +| SeUndockPrivilege | Remove computer from docking station | Required to undock a laptop.

Also, if the [discretionary access control list](https://msdn.microsoft.com/en-us/library/windows/desktop/aa374872(v=vs.85).aspx) (DACL) is changed, a 4742 event will generate, but all attributes will be “-“. + +***Important*:** If you manually change any user-related setting or attribute, for example if you set the SMARTCARD\_REQUIRED flag in **userAccountControl** for the computer account, then the **sAMAccountType** of the computer account will be changed to NORMAL\_USER\_ACCOUNT and you will get “[4738](event-4738.md): A user account was changed” instead of 4742 for this computer account. Essentially, the computer account will “become” a user account.

Each account has a unique SID that is issued by an authority, such as an Active Directory domain controller, and stored in a security database. Each time a user logs on, the system retrieves the SID for that user from the database and places it in the access token for that user. The system uses the SID in the access token to identify the user in all subsequent interactions with Windows security. When a SID has been used as the unique identifier for a user or group, it cannot ever be used again to identify another user or group.

You can change this attribute by using Active Directory Users and Computers, or through a script, for example. + +- **Home Drive** \[Type = UnicodeString\]**:** specifies the drive letter to which to map the UNC path specified by **homeDirectory** account’s attribute. The drive letter must be specified in the form “DRIVE\_LETTER:”. For example – “H:”. If the value of **homeDrive** attribute of computer object was changed, you will see the new value here. For computer objects, it is optional, and typically is not set. You can change this attribute by using Active Directory Users and Computers, or through a script, for example. + +- **Script Path** \[Type = UnicodeString\]**:** specifies the path of the account’s logon script. If the value of **scriptPath** attribute of computer object was changed, you will see the new value here. For computer objects, it is optional, and typically is not set. You can change this attribute by using Active Directory Users and Computers, or through a script, for example. + +- **Profile Path** \[Type = UnicodeString\]: specifies a path to the account's profile. This value can be a null string, a local absolute path, or a UNC path. If the value of **profilePath** attribute of computer object was changed, you will see the new value here. For computer objects, it is optional, and typically is not set. You can change this attribute by using Active Directory Users and Computers, or through a script, for example. + +- **User Workstations** \[Type = UnicodeString\]: contains the list of NetBIOS or DNS names of the computers from which the user can logon. Each computer name is separated by a comma. The name of a computer is the **sAMAccountName** property of a computer object. If the value of **userWorkstations** attribute of computer object was changed, you will see the new value here. For computer objects, it is optional, and typically is not set. You can change this attribute by using Active Directory Users and Computers, or through a script, for example. + +- **Password Last Set** \[Type = UnicodeString\]**:** last time the account’s password was modified. If the value of **pwdLastSet** attribute of computer object was changed, you will see the new value here. For example: 8/12/2015 11:41:39 AM. This value will be changed, for example, after manual computer account reset action or automatically every 30 days by default for computer objects. + +- **Account Expires** \[Type = UnicodeString\]: the date when the account expires. If the value of **accountExpires** attribute of computer object was changed, you will see the new value here. For computer objects, it is optional, and typically is not set.

You can change computer’s primary group using Active Directory Users and Computers management console in the **Member Of** tab of computer object properties. You will see a RID of new primary group as a field value. For example, 515 (Domain Computers) for workstations, is a default primary group. + +Typical **Primary Group** values for computer accounts: + +- 516 (Domain Controllers) – for domain controllers. + +- 521 (Read-only Domain Controllers) – read-only domain controllers (RODC). + +- 515 (Domain Computers) – servers and workstations. + + See this article for more information. If the value of **primaryGroupID** attribute of computer object was changed, you will see the new value here. + + + +- **AllowedToDelegateTo** \[Type = UnicodeString\]: the list of SPNs to which this account can present delegated credentials. Can be changed using Active Directory Users and Computers management console in **Delegation** tab of computer account. If the SPNs list on **Delegation** tab of a computer account was changed, you will see the new SPNs list in **AllowedToDelegateTo** field (note that you will see the new list instead of changes) of this event. This is an example of **AllowedToDelegateTo**: + + - dcom/WIN2012 + + - dcom/WIN2012.contoso.local + + If the value of **msDS-AllowedToDelegateTo** attribute of computer object was changed, you will see the new value here. + + The value can be **<value not set>**, for example, if delegation was disabled. + +> **Note**  **Service Principal Name (SPN)** is the name by which a client uniquely identifies an instance of a service. If you install multiple instances of a service on computers throughout a forest, each instance must have its own SPN. A given service instance can have multiple SPNs if there are multiple names that clients might use for authentication. For example, an SPN always includes the name of the host computer on which the service instance is running, so a service instance might register an SPN for each name or alias of its host. + +- **Old UAC Value** \[Type = UnicodeString\]: specifies flags that control password, lockout, disable/enable, script, and other behavior for the user or computer account. This parameter contains the previous value of **userAccountControl** attribute of computer object. + +- **New UAC Value** \[Type = UnicodeString\]: specifies flags that control password, lockout, disable/enable, script, and other behavior for the user or computer account. If the value of **userAccountControl** attribute of computer object was changed, you will see the new value here. + +To decode this value, you can go through the property value definitions in the “Table 7. User’s or Computer’s account UAC flags.” from largest to smallest. Compare each property value to the flags value in the event. If the flags value in the event is greater than or equal to the property value, then the property is "set" and applies to that event. Subtract the property value from the flags value in the event and note that the flag applies and then go on to the next flag. + +Here's an example: Flags value from event: 0x15 + +Decoding: + +• PASSWD\_NOTREQD 0x0020 + +• LOCKOUT 0x0010 + +• HOMEDIR\_REQUIRED 0x0008 + +• (undeclared) 0x0004 + +• ACCOUNTDISABLE 0x0002 + +• SCRIPT 0x0001 + +0x0020 > 0x15, so PASSWD\_NOTREQD does not apply to this event + +0x10 < 0x15, so LOCKOUT applies to this event. 0x15 - 0x10 = 0x5 + +0x4 < 0x5, so the undeclared value is set. We'll pretend it doesn't mean anything. 0x5 - 0x4 = 0x1 + +0x2 > 0x1, so ACCOUNTDISABLE does not apply to this event + +0x1 = 0x1, so SCRIPT applies to this event. 0x1 - 0x1 = 0x0, we're done. + +So this UAC flags value decodes to: LOCKOUT and SCRIPT + +- **User Account Control** \[Type = UnicodeString\]**:** shows the list of changes in **userAccountControl** attribute. You will see a line of text for each change. See possible values in here: “Table 7. User’s or Computer’s account UAC flags.”. In the “User Account Control field text” column, you can see text that will be displayed in the **User Account Control** field in 4742 event. + + + +- **User Parameters** \[Type = UnicodeString\]: if you change any setting using Active Directory Users and Computers management console in Dial-in tab of computer’s account properties, then you will see **<value changed, but not displayed>** in this field. + +- **SID History** \[Type = UnicodeString\]: contains previous SIDs used for the object if the object was moved from another domain. Whenever an object is moved from one domain to another, a new SID is created and becomes the objectSID. The previous SID is added to the **sIDHistory** property. If the value of **sIDHistory** attribute of computer object was changed, you will see the new value here. + +- **Logon Hours** \[Type = UnicodeString\]: hours that the account is allowed to logon to the domain. If the value of **logonHours** attribute of computer object was changed, you will see the new value here. For computer objects, it is optional, and typically is not set. You can change this attribute by using Active Directory Users and Computers, or through a script, for example. + +- **DNS Host Name** \[Type = UnicodeString\]: name of computer account as registered in DNS. If the value of **dNSHostName** attribute of computer object was changed, you will see the new value here. + + + +- **Service Principal Names** \[Type = UnicodeString\]**:** The list of SPNs, registered for computer account. If the SPN list of a computer account changed, you will see the new SPN list in **Service Principal Names** field (note that you will see the new list instead of changes).

Application servers must reject tickets which have this flag set. | +| 8 | Renewable | Used in combination with the End Time and Renew Till fields to cause tickets with long life spans to be renewed at the KDC periodically. | +| 9 | Initial | Indicates that a ticket was issued using the authentication service (AS) exchange and not issued based on a TGT. | +| 10 | Pre-authent | Indicates that the client was authenticated by the KDC before a ticket was issued. This flag usually indicates the presence of an authenticator in the ticket. It can also flag the presence of credentials taken from a smart card logon. | +| 11 | Opt-hardware-auth | This flag was originally intended to indicate that hardware-supported authentication was used during pre-authentication.

The ticket provided is encrypted in the secret key for the server on which it is valid. This option will only be honored if the ticket to be renewed has its RENEWABLE flag set and if the time in it’s renew-till field has not passed. The ticket to be renewed is passed in the padata field as part of the authentication header. | +| 31 | Validate | This option is used only by the ticket-granting service.

Usually it means that administrator should reset the password on the account. | +| 0xA | KDC\_ERR\_CANNOT\_POSTDATE | Ticket (TGT) not eligible for postdating | This error can occur if a client requests postdating of a Kerberos ticket. Postdating is the act of requesting that a ticket’s start time be set into the future.
It also can occur if there is a time difference between the client and the KDC. | +| 0xB | KDC\_ERR\_NEVER\_VALID | Requested start time is later than end time | There is a time difference between the KDC and the client. | +| 0xC | KDC\_ERR\_POLICY | Requested start time is later than end time | This error is usually the result of logon restrictions in place on a user’s account. For example workstation restriction, smart card authentication requirement or logon time restriction. | +| 0xD | KDC\_ERR\_BADOPTION | KDC cannot accommodate requested option | Impending expiration of a TGT.
The SPN to which the client is attempting to delegate credentials is not in its Allowed-to-delegate-to list | +| 0xE | KDC\_ERR\_ETYPE\_NOTSUPP | KDC has no support for encryption type | In general, this error occurs when the KDC or a client receives a packet that it cannot decrypt. | +| 0xF | KDC\_ERR\_SUMTYPE\_NOSUPP | KDC has no support for checksum type | The KDC, server, or client receives a packet for which it does not have a key of the appropriate encryption type. The result is that the computer is unable to decrypt the ticket. | +| 0x10 | KDC\_ERR\_PADATA\_TYPE\_NOSUPP | KDC has no support for PADATA type (pre-authentication data) | Smart card logon is being attempted and the proper certificate cannot be located. This can happen because the wrong certification authority (CA) is being queried or the proper CA cannot be contacted.
It can also happen when a domain controller doesn’t have a certificate installed for smart cards (Domain Controller or Domain Controller Authentication templates).
This error code cannot occur in event “[4768](event-4768.md). A Kerberos authentication ticket (TGT) was requested”. It occurs in “[4771](event-4771.md). Kerberos pre-authentication failed” event. | +| 0x11 | KDC\_ERR\_TRTYPE\_NO\_SUPP | KDC has no support for transited type | No information. | +| 0x12 | KDC\_ERR\_CLIENT\_REVOKED | Client’s credentials have been revoked | This might be because of an explicit disabling or because of other restrictions in place on the account. For example: account disabled, expired, or locked out. | +| 0x13 | KDC\_ERR\_SERVICE\_REVOKED | Credentials for server have been revoked | No information. | +| 0x14 | KDC\_ERR\_TGT\_REVOKED | TGT has been revoked | Since the remote KDC may change its PKCROSS key while there are PKCROSS tickets still active, it SHOULD cache the old PKCROSS keys until the last issued PKCROSS ticket expires. Otherwise, the remote KDC will respond to a client with a KRB-ERROR message of type KDC\_ERR\_TGT\_REVOKED. See [RFC1510](https://www.ietf.org/proceedings/49/I-D/draft-ietf-cat-kerberos-pk-cross-07.txt) for more details. | +| 0x15 | KDC\_ERR\_CLIENT\_NOTYET | Client not yet valid—try again later | No information. | +| 0x16 | KDC\_ERR\_SERVICE\_NOTYET | Server not yet valid—try again later | No information. | +| 0x17 | KDC\_ERR\_KEY\_EXPIRED | Password has expired—change password to reset | The user’s password has expired.
This error code cannot occur in event “[4768](event-4768.md). A Kerberos authentication ticket (TGT) was requested”. It occurs in “[4771](event-4771.md). Kerberos pre-authentication failed” event. | +| 0x18 | KDC\_ERR\_PREAUTH\_FAILED | Pre-authentication information was invalid | The wrong password was provided.
This error code cannot occur in event “[4768](event-4768.md). A Kerberos authentication ticket (TGT) was requested”. It occurs in “[4771](event-4771.md). Kerberos pre-authentication failed” event. | +| 0x19 | KDC\_ERR\_PREAUTH\_REQUIRED | Additional pre-authentication required | This error often occurs in UNIX interoperability scenarios. MIT-Kerberos clients do not request pre-authentication when they send a KRB\_AS\_REQ message. If pre-authentication is required (the default), Windows systems will send this error. Most MIT-Kerberos clients will respond to this error by giving the pre-authentication, in which case the error can be ignored, but some clients might not respond in this way. | +| 0x1A | KDC\_ERR\_SERVER\_NOMATCH | KDC does not know about the requested server | No information. | +| 0x1B | KDC\_ERR\_SVC\_UNAVAILABLE | KDC is unavailable | No information. | +| 0x1F | KRB\_AP\_ERR\_BAD\_INTEGRITY | Integrity check on decrypted field failed | The authenticator was encrypted with something other than the session key. The result is that the client cannot decrypt the resulting message. The modification of the message could be the result of an attack or it could be because of network noise. | +| 0x20 | KRB\_AP\_ERR\_TKT\_EXPIRED | The ticket has expired | The smaller the value for the “Maximum lifetime for user ticket” Kerberos policy setting, the more likely it is that this error will occur. Because ticket renewal is automatic, you should not have to do anything if you get this message. | +| 0x21 | KRB\_AP\_ERR\_TKT\_NYV | The ticket is not yet valid | The ticket presented to the server is not yet valid (in relationship to the server time). The most probable cause is that the clocks on the KDC and the client are not synchronized.
If cross-realm Kerberos authentication is being attempted, then you should verify time synchronization between the KDC in the target realm and the KDC in the client realm, as well. | +| 0x22 | KRB\_AP\_ERR\_REPEAT | The request is a replay | This error indicates that a specific authenticator showed up twice — the KDC has detected that this session ticket duplicates one that it has already received. | +| 0x23 | KRB\_AP\_ERR\_NOT\_US | The ticket is not for us | The server has received a ticket that was meant for a different realm. | +| 0x24 | KRB\_AP\_ERR\_BADMATCH | The ticket and authenticator do not match | The KRB\_TGS\_REQ is being sent to the wrong KDC.
There is an account mismatch during protocol transition. | +| 0x25 | KRB\_AP\_ERR\_SKEW | The clock skew is too great | This error is logged if a client computer sends a timestamp whose value differs from that of the server’s timestamp by more than the number of minutes found in the “Maximum tolerance for computer clock synchronization” setting in Kerberos policy. | +| 0x26 | KRB\_AP\_ERR\_BADADDR | Network address in network layer header doesn't match address inside ticket | Session tickets MAY include the addresses from which they are valid. This error can occur if the address of the computer sending the ticket is different from the valid address in the ticket. A possible cause of this could be an Internet Protocol (IP) address change. Another possible cause is when a ticket is passed through a proxy server or NAT. The client is unaware of the address scheme used by the proxy server, so unless the program caused the client to request a proxy server ticket with the proxy server's source address, the ticket could be invalid. | +| 0x27 | KRB\_AP\_ERR\_BADVERSION | Protocol version numbers don't match (PVNO) | When an application receives a KRB\_SAFE message, it verifies it. If any error occurs, an error code is reported for use by the application.
The message is first checked by verifying that the protocol version and type fields match the current version and KRB\_SAFE, respectively. A mismatch generates a KRB\_AP\_ERR\_BADVERSION.
See [RFC4120](http://www.ietf.org/rfc/rfc4120.txt) for more details. | +| 0x28 | KRB\_AP\_ERR\_MSG\_TYPE | Message type is unsupported | This message is generated when target server finds that message format is wrong. This applies to KRB\_AP\_REQ, KRB\_SAFE, KRB\_PRIV and KRB\_CRED messages.
This error also generated if use of UDP protocol is being attempted with User-to-User authentication. | +| 0x29 | KRB\_AP\_ERR\_MODIFIED | Message stream modified and checksum didn't match | The authentication data was encrypted with the wrong key for the intended server.
The authentication data was modified in transit by a hardware or software error, or by an attacker.
The client sent the authentication data to the wrong server because incorrect DNS data caused the client to send the request to the wrong server.
The client sent the authentication data to the wrong server because DNS data was out-of-date on the client. | +| 0x2A | KRB\_AP\_ERR\_BADORDER | Message out of order (possible tampering) | This event generates for KRB\_SAFE and KRB\_PRIV messages if an incorrect sequence number is included, or if a sequence number is expected but not present. See [RFC4120](http://www.ietf.org/rfc/rfc4120.txt) for more details. | +| 0x2C | KRB\_AP\_ERR\_BADKEYVER | Specified version of key is not available | This error might be generated on server side during receipt of invalid KRB\_AP\_REQ message. If the key version indicated by the Ticket in the KRB\_AP\_REQ is not one the server can use (e.g., it indicates an old key, and the server no longer possesses a copy of the old key), the KRB\_AP\_ERR\_BADKEYVER error is returned. | +| 0x2D | KRB\_AP\_ERR\_NOKEY | Service key not available | This error might be generated on server side during receipt of invalid KRB\_AP\_REQ message. Because it is possible for the server to be registered in multiple realms, with different keys in each, the realm field in the unencrypted portion of the ticket in the KRB\_AP\_REQ is used to specify which secret key the server should use to decrypt that ticket. The KRB\_AP\_ERR\_NOKEY error code is returned if the server doesn't have the proper key to decipher the ticket. | +| 0x2E | KRB\_AP\_ERR\_MUT\_FAIL | Mutual authentication failed | No information. | +| 0x2F | KRB\_AP\_ERR\_BADDIRECTION | Incorrect message direction | No information. | +| 0x30 | KRB\_AP\_ERR\_METHOD | Alternative authentication method required | According [RFC4120](http://www.ietf.org/rfc/rfc4120.txt) this error message is obsolete. | +| 0x31 | KRB\_AP\_ERR\_BADSEQ | Incorrect sequence number in message | No information. | +| 0x32 | KRB\_AP\_ERR\_INAPP\_CKSUM | Inappropriate type of checksum in message (checksum may be unsupported) | When KDC receives KRB\_TGS\_REQ message it decrypts it, and after that, the user-supplied checksum in the Authenticator MUST be verified against the contents of the request. The message MUST be rejected either if the checksums do not match (with an error code of KRB\_AP\_ERR\_MODIFIED) or if the checksum is not collision-proof (with an error code of KRB\_AP\_ERR\_INAPP\_CKSUM). | +| 0x33 | KRB\_AP\_PATH\_NOT\_ACCEPTED | Desired path is unreachable | No information. | +| 0x34 | KRB\_ERR\_RESPONSE\_TOO\_BIG | Too much data | The size of a ticket is too large to be transmitted reliably via UDP. In a Windows environment, this message is purely informational. A computer running a Windows operating system will automatically try TCP if UDP fails. | +| 0x3C | KRB\_ERR\_GENERIC | Generic error | Group membership has overloaded the PAC.
Multiple recent password changes have not propagated.
Crypto subsystem error caused by running out of memory.
SPN too long.
SPN has too many parts. | +| 0x3D | KRB\_ERR\_FIELD\_TOOLONG | Field is too long for this implementation | Each request (KRB\_KDC\_REQ) and response (KRB\_KDC\_REP or KRB\_ERROR) sent over the TCP stream is preceded by the length of the request as 4 octets in network byte order. The high bit of the length is reserved for future expansion and MUST currently be set to zero. If a KDC that does not understand how to interpret a set high bit of the length encoding receives a request with the high order bit of the length set, it MUST return a KRB-ERROR message with the error KRB\_ERR\_FIELD\_TOOLONG and MUST close the TCP stream. | +| 0x3E | KDC\_ERR\_CLIENT\_NOT\_TRUSTED | The client trust failed or is not implemented | This typically happens when user’s smart-card certificate is revoked or the root Certification Authority that issued the smart card certificate (in a chain) is not trusted by the domain controller. | +| 0x3F | KDC\_ERR\_KDC\_NOT\_TRUSTED | The KDC server trust failed or could not be verified | The trustedCertifiers field contains a list of certification authorities trusted by the client, in the case that the client does not possess the KDC's public key certificate. If the KDC has no certificate signed by any of the trustedCertifiers, then it returns an error of type KDC\_ERR\_KDC\_NOT\_TRUSTED. See [RFC1510](https://www.ietf.org/proceedings/50/I-D/cat-kerberos-pk-init-13.txt) for more details. | +| 0x40 | KDC\_ERR\_INVALID\_SIG | The signature is invalid | This error is related to PKINIT. If a PKI trust relationship exists, the KDC then verifies the client's signature on AuthPack (TGT request signature). If that fails, the KDC returns an error message of type KDC\_ERR\_INVALID\_SIG. | +| 0x41 | KDC\_ERR\_KEY\_TOO\_WEAK | A higher encryption level is needed | If the clientPublicValue field is filled in, indicating that the client wishes to use Diffie-Hellman key agreement, then the KDC checks to see that the parameters satisfy its policy. If they do not (e.g., the prime size is insufficient for the expected encryption type), then the KDC sends back an error message of type KDC\_ERR\_KEY\_TOO\_WEAK. | +| 0x42 | KRB\_AP\_ERR\_USER\_TO\_USER\_REQUIRED | User-to-user authorization is required | In the case that the client application doesn't know that a service requires user-to-user authentication, and requests and receives a conventional KRB\_AP\_REP, the client will send the KRB\_AP\_REP request, and the server will respond with a KRB\_ERROR token as described in [RFC1964](https://tools.ietf.org/html/rfc1964), with a msg-type of KRB\_AP\_ERR\_USER\_TO\_USER\_REQUIRED. | +| 0x43 | KRB\_AP\_ERR\_NO\_TGT | No TGT was presented or available | In user-to-user authentication if the service does not possess a ticket granting ticket, it should return the error KRB\_AP\_ERR\_NO\_TGT. | +| 0x44 | KDC\_ERR\_WRONG\_REALM | Incorrect domain or principal | Although this error rarely occurs, it occurs when a client presents a cross-realm TGT to a realm other than the one specified in the TGT. Typically, this results from incorrectly configured DNS. | + +> Table 3.

If the SID cannot be resolved, you will see the source data in the event. + + - **NULL SID** – this value shows in Failure events. + +> **Note**  A **security identifier (SID)** is a unique value of variable length used to identify a trustee (security principal). Each account has a unique SID that is issued by an authority, such as an Active Directory domain controller, and stored in a security database. Each time a user logs on, the system retrieves the SID for that user from the database and places it in the access token for that user. The system uses the SID in the access token to identify the user in all subsequent interactions with Windows security. When a SID has been used as the unique identifier for a user or group, it cannot ever be used again to identify another user or group. For more information about SIDs, see [Security Identifiers](https://msdn.microsoft.com/en-us/library/windows/desktop/aa379571(v=vs.85).aspx). + +**Network Information:** + +- **Client Address** \[Type = UnicodeString\]**:** IP address of the computer from which the TGS request was received.

Tells the ticket-granting service that it can issue a new TGT—based on the presented TGT—with a different network address based on the presented TGT. | +| 2 | Forwarded | Indicates either that a TGT has been forwarded or that a ticket was issued from a forwarded TGT. | +| 3 | Proxiable | (TGT only). Tells the ticket-granting service that it can issue tickets with a network address that differs from the one in the TGT. | +| 4 | Proxy | Indicates that the network address in the ticket is different from the one in the TGT used to obtain the ticket. | +| 5 | Allow-postdate | Postdated tickets SHOULD NOT be supported in [KILE](https://msdn.microsoft.com/en-us/library/cc233855.aspx) (Microsoft Kerberos Protocol Extension). | +| 6 | Postdated | Postdated tickets SHOULD NOT be supported in [KILE](https://msdn.microsoft.com/en-us/library/cc233855.aspx) (Microsoft Kerberos Protocol Extension). | +| 7 | Invalid | This flag indicates that a ticket is invalid, and it must be validated by the KDC before use. Application servers must reject tickets which have this flag set. | +| 8 | Renewable | Used in combination with the End Time and Renew Till fields to cause tickets with long life spans to be renewed at the KDC periodically. | +| 9 | Initial | Indicates that a ticket was issued using the authentication service (AS) exchange and not issued based on a TGT. | +| 10 | Pre-authent | Indicates that the client was authenticated by the KDC before a ticket was issued. This flag usually indicates the presence of an authenticator in the ticket. It can also flag the presence of credentials taken from a smart card logon. | +| 11 | Opt-hardware-auth | This flag was originally intended to indicate that hardware-supported authentication was used during pre-authentication. This flag is no longer recommended in the Kerberos V5 protocol. KDCs MUST NOT issue a ticket with this flag set. KDCs SHOULD NOT preserve this flag if it is set by another KDC. | +| 12 | Transited-policy-checked | KILE MUST NOT check for transited domains on servers or a KDC. Application servers MUST ignore the TRANSITED-POLICY-CHECKED flag. | +| 13 | Ok-as-delegate | The KDC MUST set the OK-AS-DELEGATE flag if the service account is trusted for delegation. | +| 14 | Request-anonymous | KILE not use this flag. | +| 15 | Name-canonicalize | In order to request referrals the Kerberos client MUST explicitly request the "canonicalize" KDC option for the AS-REQ or TGS-REQ. | +| 16-25 | Unused | - | +| 26 | Disable-transited-check | By default the KDC will check the transited field of a TGT against the policy of the local realm before it will issue derivative tickets based on the TGT. If this flag is set in the request, checking of the transited field is disabled. Tickets issued without the performance of this check will be noted by the reset (0) value of the TRANSITED-POLICY-CHECKED flag, indicating to the application server that the transited field must be checked locally. KDCs are encouraged but not required to honor
the DISABLE-TRANSITED-CHECK option.
Should not be in use, because Transited-policy-checked flag is not supported by KILE. | +| 27 | Renewable-ok | The RENEWABLE-OK option indicates that a renewable ticket will be acceptable if a ticket with the requested life cannot otherwise be provided, in which case a renewable ticket may be issued with a renew-till equal to the requested end time. The value of the renew-till field may still be limited by local limits, or limits selected by the individual principal or server. | +| 28 | Enc-tkt-in-skey | No information. | +| 29 | Unused | - | +| 30 | Renew | The RENEW option indicates that the present request is for a renewal. The ticket provided is encrypted in the secret key for the server on which it is valid. This option will only be honored if the ticket to be renewed has its RENEWABLE flag set and if the time in its renew-till field has not passed. The ticket to be renewed is passed in the padata field as part of the authentication header. | +| 31 | Validate | This option is used only by the ticket-granting service. The VALIDATE option indicates that the request is to validate a postdated ticket. Should not be in use, because postdated tickets are not supported by KILE. +## Table 4.

This error is similar to KDC\_ERR\_C\_PRINCIPAL\_UNKNOWN except that it occurs when the server name cannot be found. | +| 0x8 | KDC\_ERR\_PRINCIPAL\_NOT\_UNIQUE | Multiple principal entries in KDC database | This error occurs if duplicate principal names exist. Unique principal names are crucial for ensuring mutual authentication. Thus, duplicate principal names are strictly forbidden, even across multiple realms. Without unique principal names, the client has no way of ensuring that the server it is communicating with is the correct one. | +| 0x9 | KDC\_ERR\_NULL\_KEY | The client or server has a null key (master key) | No master key was found for client or server. Usually it means that administrator should reset the password on the account. | +| 0xA | KDC\_ERR\_CANNOT\_POSTDATE | Ticket (TGT) not eligible for postdating | This error can occur if a client requests postdating of a Kerberos ticket. Postdating is the act of requesting that a ticket’s start time be set into the future.
It also can occur if there is a time difference between the client and the KDC. | +| 0xB | KDC\_ERR\_NEVER\_VALID | Requested start time is later than end time | There is a time difference between the KDC and the client. | +| 0xC | KDC\_ERR\_POLICY | Requested start time is later than end time | This error is usually the result of logon restrictions in place on a user’s account. For example workstation restriction, smart card authentication requirement or logon time restriction. | +| 0xD | KDC\_ERR\_BADOPTION | KDC cannot accommodate requested option | Impending expiration of a TGT.
The SPN to which the client is attempting to delegate credentials is not in its Allowed-to-delegate-to list | +| 0xE | KDC\_ERR\_ETYPE\_NOTSUPP | KDC has no support for encryption type | In general, this error occurs when the KDC or a client receives a packet that it cannot decrypt. | +| 0xF | KDC\_ERR\_SUMTYPE\_NOSUPP | KDC has no support for checksum type | The KDC, server, or client receives a packet for which it does not have a key of the appropriate encryption type. The result is that the computer is unable to decrypt the ticket. | +| 0x10 | KDC\_ERR\_PADATA\_TYPE\_NOSUPP | KDC has no support for PADATA type (pre-authentication data) | Smart card logon is being attempted and the proper certificate cannot be located. This can happen because the wrong certification authority (CA) is being queried or the proper CA cannot be contacted.
It can also happen when a domain controller doesn’t have a certificate installed for smart cards (Domain Controller or Domain Controller Authentication templates).
This error code cannot occur in event “[4768](event-4768.md). A Kerberos authentication ticket (TGT) was requested”. It occurs in “[4771](event-4771.md). Kerberos pre-authentication failed” event. | +| 0x11 | KDC\_ERR\_TRTYPE\_NO\_SUPP | KDC has no support for transited type | No information. | +| 0x12 | KDC\_ERR\_CLIENT\_REVOKED | Client’s credentials have been revoked | This might be because of an explicit disabling or because of other restrictions in place on the account. For example: account disabled, expired, or locked out. | +| 0x13 | KDC\_ERR\_SERVICE\_REVOKED | Credentials for server have been revoked | No information. | +| 0x14 | KDC\_ERR\_TGT\_REVOKED | TGT has been revoked | Since the remote KDC may change its PKCROSS key while there are PKCROSS tickets still active, it SHOULD cache the old PKCROSS keys until the last issued PKCROSS ticket expires. Otherwise, the remote KDC will respond to a client with a KRB-ERROR message of type KDC\_ERR\_TGT\_REVOKED. See [RFC1510](https://www.ietf.org/proceedings/49/I-D/draft-ietf-cat-kerberos-pk-cross-07.txt) for more details. | +| 0x15 | KDC\_ERR\_CLIENT\_NOTYET | Client not yet valid—try again later | No information. | +| 0x16 | KDC\_ERR\_SERVICE\_NOTYET | Server not yet valid—try again later | No information. | +| 0x17 | KDC\_ERR\_KEY\_EXPIRED | Password has expired—change password to reset | The user’s password has expired.
This error code cannot occur in event “[4768](event-4768.md). A Kerberos authentication ticket (TGT) was requested”. It occurs in “[4771](event-4771.md). Kerberos pre-authentication failed” event. | +| 0x18 | KDC\_ERR\_PREAUTH\_FAILED | Pre-authentication information was invalid | The wrong password was provided.
This error code cannot occur in event “[4768](event-4768.md). A Kerberos authentication ticket (TGT) was requested”. It occurs in “[4771](event-4771.md). Kerberos pre-authentication failed” event. | +| 0x19 | KDC\_ERR\_PREAUTH\_REQUIRED | Additional pre-authentication required | This error often occurs in UNIX interoperability scenarios. MIT-Kerberos clients do not request pre-authentication when they send a KRB\_AS\_REQ message. If pre-authentication is required (the default), Windows systems will send this error. Most MIT-Kerberos clients will respond to this error by giving the pre-authentication, in which case the error can be ignored, but some clients might not respond in this way. | +| 0x1A | KDC\_ERR\_SERVER\_NOMATCH | KDC does not know about the requested server | No information. | +| 0x1B | KDC\_ERR\_SVC\_UNAVAILABLE | KDC is unavailable | No information. | +| 0x1F | KRB\_AP\_ERR\_BAD\_INTEGRITY | Integrity check on decrypted field failed | The authenticator was encrypted with something other than the session key. The result is that the client cannot decrypt the resulting message. The modification of the message could be the result of an attack or it could be because of network noise. | +| 0x20 | KRB\_AP\_ERR\_TKT\_EXPIRED | The ticket has expired | The smaller the value for the “Maximum lifetime for user ticket” Kerberos policy setting, the more likely it is that this error will occur. Because ticket renewal is automatic, you should not have to do anything if you get this message. | +| 0x21 | KRB\_AP\_ERR\_TKT\_NYV | The ticket is not yet valid | The ticket presented to the server is not yet valid (in relationship to the server time). The most probable cause is that the clocks on the KDC and the client are not synchronized.
If cross-realm Kerberos authentication is being attempted, then you should verify time synchronization between the KDC in the target realm and the KDC in the client realm, as well. | +| 0x22 | KRB\_AP\_ERR\_REPEAT | The request is a replay | This error indicates that a specific authenticator showed up twice — the KDC has detected that this session ticket duplicates one that it has already received. | +| 0x23 | KRB\_AP\_ERR\_NOT\_US | The ticket is not for us | The server has received a ticket that was meant for a different realm. | +| 0x24 | KRB\_AP\_ERR\_BADMATCH | The ticket and authenticator do not match | The KRB\_TGS\_REQ is being sent to the wrong KDC.
There is an account mismatch during protocol transition. | +| 0x25 | KRB\_AP\_ERR\_SKEW | The clock skew is too great | This error is logged if a client computer sends a timestamp whose value differs from that of the server’s timestamp by more than the number of minutes found in the “Maximum tolerance for computer clock synchronization” setting in Kerberos policy. | +| 0x26 | KRB\_AP\_ERR\_BADADDR | Network address in network layer header doesn't match address inside ticket | Session tickets MAY include the addresses from which they are valid. This error can occur if the address of the computer sending the ticket is different from the valid address in the ticket. A possible cause of this could be an Internet Protocol (IP) address change. Another possible cause is when a ticket is passed through a proxy server or NAT. The client is unaware of the address scheme used by the proxy server, so unless the program caused the client to request a proxy server ticket with the proxy server's source address, the ticket could be invalid. | +| 0x27 | KRB\_AP\_ERR\_BADVERSION | Protocol version numbers don't match (PVNO) | When an application receives a KRB\_SAFE message, it verifies it. If any error occurs, an error code is reported for use by the application.
The message is first checked by verifying that the protocol version and type fields match the current version and KRB\_SAFE, respectively. A mismatch generates a KRB\_AP\_ERR\_BADVERSION.
See [RFC4120](http://www.ietf.org/rfc/rfc4120.txt) for more details. | +| 0x28 | KRB\_AP\_ERR\_MSG\_TYPE | Message type is unsupported | This message is generated when target server finds that message format is wrong. This applies to KRB\_AP\_REQ, KRB\_SAFE, KRB\_PRIV and KRB\_CRED messages.
This error also generated if use of UDP protocol is being attempted with User-to-User authentication. | +| 0x29 | KRB\_AP\_ERR\_MODIFIED | Message stream modified and checksum didn't match | The authentication data was encrypted with the wrong key for the intended server.
The authentication data was modified in transit by a hardware or software error, or by an attacker.
The client sent the authentication data to the wrong server because incorrect DNS data caused the client to send the request to the wrong server.
The client sent the authentication data to the wrong server because DNS data was out-of-date on the client. | +| 0x2A | KRB\_AP\_ERR\_BADORDER | Message out of order (possible tampering) | This event generates for KRB\_SAFE and KRB\_PRIV messages if an incorrect sequence number is included, or if a sequence number is expected but not present. See [RFC4120](http://www.ietf.org/rfc/rfc4120.txt) for more details. | +| 0x2C | KRB\_AP\_ERR\_BADKEYVER | Specified version of key is not available | This error might be generated on server side during receipt of invalid KRB\_AP\_REQ message. If the key version indicated by the Ticket in the KRB\_AP\_REQ is not one the server can use (e.g., it indicates an old key, and the server no longer possesses a copy of the old key), the KRB\_AP\_ERR\_BADKEYVER error is returned. | +| 0x2D | KRB\_AP\_ERR\_NOKEY | Service key not available | This error might be generated on server side during receipt of invalid KRB\_AP\_REQ message. Because it is possible for the server to be registered in multiple realms, with different keys in each, the realm field in the unencrypted portion of the ticket in the KRB\_AP\_REQ is used to specify which secret key the server should use to decrypt that ticket. The KRB\_AP\_ERR\_NOKEY error code is returned if the server doesn't have the proper key to decipher the ticket. | +| 0x2E | KRB\_AP\_ERR\_MUT\_FAIL | Mutual authentication failed | No information. | +| 0x2F | KRB\_AP\_ERR\_BADDIRECTION | Incorrect message direction | No information. | +| 0x30 | KRB\_AP\_ERR\_METHOD | Alternative authentication method required | According [RFC4120](http://www.ietf.org/rfc/rfc4120.txt) this error message is obsolete. | +| 0x31 | KRB\_AP\_ERR\_BADSEQ | Incorrect sequence number in message | No information. | +| 0x32 | KRB\_AP\_ERR\_INAPP\_CKSUM | Inappropriate type of checksum in message (checksum may be unsupported) | When KDC receives KRB\_TGS\_REQ message it decrypts it, and after the user-supplied checksum in the Authenticator MUST be verified against the contents of the request, and the message MUST be rejected if the checksums do not match (with an error code of KRB\_AP\_ERR\_MODIFIED) or if the checksum is not collision-proof (with an error code of KRB\_AP\_ERR\_INAPP\_CKSUM). | +| 0x33 | KRB\_AP\_PATH\_NOT\_ACCEPTED | Desired path is unreachable | No information. | +| 0x34 | KRB\_ERR\_RESPONSE\_TOO\_BIG | Too much data | The size of a ticket is too large to be transmitted reliably via UDP. In a Windows environment, this message is purely informational. A computer running a Windows operating system will automatically try TCP if UDP fails. | +| 0x3C | KRB\_ERR\_GENERIC | Generic error | Group membership has overloaded the PAC.
Multiple recent password changes have not propagated.
Crypto subsystem error caused by running out of memory.
SPN too long.
SPN has too many parts. | +| 0x3D | KRB\_ERR\_FIELD\_TOOLONG | Field is too long for this implementation | Each request (KRB\_KDC\_REQ) and response (KRB\_KDC\_REP or KRB\_ERROR) sent over the TCP stream is preceded by the length of the request as 4 octets in network byte order. The high bit of the length is reserved for future expansion and MUST currently be set to zero. If a KDC that does not understand how to interpret a set high bit of the length encoding receives a request with the high order bit of the length set, it MUST return a KRB-ERROR message with the error KRB\_ERR\_FIELD\_TOOLONG and MUST close the TCP stream. | +| 0x3E | KDC\_ERR\_CLIENT\_NOT\_TRUSTED | The client trust failed or is not implemented | This typically happens when user’s smart-card certificate is revoked or the root Certification Authority that issued the smart card certificate (in a chain) is not trusted by the domain controller. | +| 0x3F | KDC\_ERR\_KDC\_NOT\_TRUSTED | The KDC server trust failed or could not be verified | The trustedCertifiers field contains a list of certification authorities trusted by the client, in the case that the client does not possess the KDC's public key certificate. If the KDC has no certificate signed by any of the trustedCertifiers, then it returns an error of type KDC\_ERR\_KDC\_NOT\_TRUSTED. See [RFC1510](https://www.ietf.org/proceedings/50/I-D/cat-kerberos-pk-init-13.txt) for more details. | +| 0x40 | KDC\_ERR\_INVALID\_SIG | The signature is invalid | This error is related to PKINIT. If a PKI trust relationship exists, the KDC then verifies the client's signature on AuthPack (TGT request signature). If that fails, the KDC returns an error message of type KDC\_ERR\_INVALID\_SIG. | +| 0x41 | KDC\_ERR\_KEY\_TOO\_WEAK | A higher encryption level is needed | If the clientPublicValue field is filled in, indicating that the client wishes to use Diffie-Hellman key agreement, then the KDC checks to see that the parameters satisfy its policy. If they do not (e.g., the prime size is insufficient for the expected encryption type), then the KDC sends back an error message of type KDC\_ERR\_KEY\_TOO\_WEAK. | +| 0x42 | KRB\_AP\_ERR\_USER\_TO\_USER\_REQUIRED | User-to-user authorization is required | In the case that the client application doesn't know that a service requires user-to-user authentication, and requests and receives a conventional KRB\_AP\_REP, the client will send the KRB\_AP\_REP request, and the server will respond with a KRB\_ERROR token as described in [RFC1964](https://tools.ietf.org/html/rfc1964), with a msg-type of KRB\_AP\_ERR\_USER\_TO\_USER\_REQUIRED. | +| 0x43 | KRB\_AP\_ERR\_NO\_TGT | No TGT was presented or available | In user-to-user authentication if the service does not possess a ticket granting ticket, it should return the error KRB\_AP\_ERR\_NO\_TGT. | +| 0x44 | KDC\_ERR\_WRONG\_REALM | Incorrect domain or principal | Although this error rarely occurs, it occurs when a client presents a cross-realm TGT to a realm other than the one specified in the TGT. Typically, this results from incorrectly configured DNS. | + +- **Transited Services** \[Type = UnicodeString\]: this field contains list of SPNs which were requested if Kerberos delegation was used. + +> **Note**  **Service Principal Name (SPN)** is the name by which a client uniquely identifies an instance of a service. If you install multiple instances of a service on computers throughout a forest, each instance must have its own SPN. A given service instance can have multiple SPNs if there are multiple names that clients might use for authentication. For example, an SPN always includes the name of the host computer on which the service instance is running, so a service instance might register an SPN for each name or alias of its host. + +## Security Monitoring Recommendations + +For 4769(S, F): A Kerberos service ticket was requested. + +| **Type of monitoring required** | **Recommendation** | +|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| +| **High-value accounts**: You might have high-value domain or local accounts for which you need to monitor each action.

Key infrastructure servers such as DNS servers and DHCP servers typically must be available to all devicess on the internal network, yet secured from network attacks. However, if they must remain available to all devicess on the network, not just to isolated domain members, then these servers cannot require IPsec for inbound access, nor can they use IPsec transport mode for outbound traffic. + +In addition to the infrastructure servers mentioned earlier, there might also be other servers on the network that trusted devices cannot use IPsec to access, which would be added to the exemption list. + +Generally, the following conditions are reasons to consider adding a device to the exemption list: + +- If the device must be accessed by trusted devices but it does not have a compatible IPsec implementation. + +- If the device must provide services to both trusted and untrusted devices, but does not meet the criteria for membership in the boundary zone. + +- If the device must be accessed by trusted devices from different isolated domains that do not have an Active Directory trust relationship established with each other. + +- If the device is a domain controller running version of Windows earlier than Windows Server 2008, or if any of its clients are running a version of Windows earlier than Windows Vista. + +- If the device must support trusted and untrusted devices, but cannot use IPsec to help secure communications to trusted devices. + +For large organizations, the list of exemptions might grow very large if all the exemptions are implemented by one connection security rule for the whole domain or for all trusted forests. If you can require all devices in your isolated domain to run at least Windows Vista or Windows Server 2008, you can greatly reduce the size of this list. A large exemption list has several unwanted effects on every device that receives the GPO, including the following: + +- Reduces the overall effectiveness of isolation. + +- Creates a larger management burden (because of frequent updates). + +- Increases the size of the IPsec policy, which means that it consumes more memory and CPU resources, slows down network throughput, and increases the time required to download and apply the GPO containing the IPsec policy. + +To keep the number of exemptions as small as possible, you have several options: + +- Carefully consider the communications requirements of each isolation zone, especially server-only zones. They might not be required to communicate with every exemption in the domain-level policy for clients. + +- Consolidate server functions. If several exempt services can be hosted at one IP address, the number of exemptions is reduced. + +- Consolidate exempted hosts on the same subnet. Where network traffic volume allows, you might be able to locate the servers on a subnet that is exempted, instead of using exemptions for each IP address. + +As with defining the boundary zone, create a formal process to approve hosts being added to the exemption list.

A significant number of the devices at Woodgrove Bank continue to run Windows Vista and Windows Server 2008. Interoperability between the previous and newer operating systems must be maintained. Wherever possible, security features applied to the newer operating systems must also be applied to the previous operating systems. + +A key line-of-business program called WGBank consists of a client program running on most of the desktop devices in the organization.

The network infrastructure servers that are running services, such as Active Directory, DNS, DHCP, or WINS, can receive unsolicited inbound requests from network clients.

The WGBank front-end servers can receive unsolicited inbound traffic from the client devices and the WGBank partner servers.

The WGBank front-end servers can receive the corresponding responses. + +5. There is no direct communications between the client devices and the WGBank back-end devices. + +6. There is no unsolicited traffic from the WGBank back-end devices to the WGBank front-end servers. + +7. Company policy prohibits the use of peer-to-peer file transfer software. A recent review by the IT staff found that although the perimeter firewall does prevent most of the programs in this category from working, two programs are being used by staff members that do not require an outside server.

Therefore the firewall GPOs will not be linked directly to OUs that hold the relevant devices. Instead, the GPOs are linked to the domain container in Active Directory, and then WMI and group filters are attached to the GPO to ensure that it is applied to the correct devices. + +Setting up groups as described here ensures that you do not have to know what operating system a computer is running before assigning it to a group. A combination of WMI filters and security group filters are used to ensure that members of the group receive the GPO appropriate for the version of Windows running on that computer. For some groups, you might have four or even five GPOs. + +The following groups were created by using the Active Directory Users and Computers Microsoft Management Console (MMC) snap-in, and all devices that run Windows were added to the correct groups: + +- **CG\_FIREWALL\_ALLCOMPUTERS**. Add the predefined and system managed **Domain computers** group as a member of this group. All members of the FIREWALL\_ALLCOMPUTERS group receive an operating system-specific GPO with the common firewall rules applied to all devices. + + The two device types (client and server) are distinguished by using a WMI filters to ensure that only the policy intended for devices that are running a client version of Windows can be applied to that computer. A similar WMI filter on the server GPO ensures that only devices that are running server versions of Windows can apply that GPO. Each of the GPOs also have security group filters to prevent members of the group FIREWALL\_NO\_DEFAULT from receiving either of these two GPOs. + + - Client devices receive a GPO that configures Windows Firewall with Advanced Security to enforce the default Windows Firewall behavior (allow outbound, block unsolicited inbound). The client default GPO also includes the built-in firewall rule groups Core Networking and File and Printer Sharing. The Core Networking group is enabled for all profiles, whereas the File and Printer Sharing group is enabled for only the Domain and Private profiles. The GPO also includes inbound firewall rules to allow the WGBank front-end server dashboard update traffic, and rules to prevent company-prohibited programs from sending or receiving network traffic, both inbound and outbound. + + - Server devices receive a GPO that includes similar firewall configuration to the client computer GPO. The primary difference is that the rules are enabled for all profiles (not just domain and private). Also, the rules for WGBank dashboard update are not included, because it is not needed on server devices. + + All rules are scoped to allow network traffic only from devices on Woodgrove Bank's corporate network. + +- **CG\_FIREWALL\_NO\_DEFAULT**. Members of this group do not receive the default firewall GPO. Devices are added to this group if there is a business requirement for it to be exempted from the default firewall behavior. The use of a group to represent the exceptions instead of the group members directly makes it easier to support the dynamic nature of the client computer population. A new computer joined to the domain is automatically given the appropriate default firewall GPO, unless it is a member of this group. + +- **CG\_FIREWALL\_WGB\_FE**. This group contains the computer accounts for all the WGBank front-end server devices.

Members of this group receive a GPO that configures Windows Firewall with Advanced Security with inbound firewall rules to allow the SQL Server program to receive unsolicited queries only from the WGBank front-end servers. Devices in this group also receive the default firewall GPO. + +- **CG\_FIREWALL\_BOUNDARY\_WGBANKFE**. This group contains the computer accounts for the servers that host Web services that can be accessed from the Internet. Members of this group receive a GPO that adds an inbound firewall rule to allow inbound HTTP and HTTPS network traffic from any address, including the Internet. Devices in this group also receive the default firewall GPO. + +- **CG\_FIREWALL\_WINS**. This group contains the computer accounts for all the WINS server devices.

You must understand the current Active Directory architecture to determine the most effective strategy for deploying your firewall and connection security rules using Group Policy. It also enables you to understand which devices can be isolated and how best to accomplish the required degree of isolation. + +- **Names and number of domains**. Authentication in server and domain isolation uses the IKE negotiation process with the Kerberos V5 protocol. This protocol assumes that devices are domain members. + +- **Number and types of trusts**. Trusts affect the logical boundaries of domain isolation and define whether IKE negotiation can occur between devices in different Active Directory domains. + +- **Names and number of sites**. Site architecture is usually aligned with the network topology. Understanding how sites are defined in Active Directory will help provide insight into replication and other details. Site architecture can provide a better understanding of the current Active Directory deployment. + +- **OU structure**. OUs are logical constructs and can therefore be molded to fit many different requirements and goals. The OU structure is an ideal place to examine how Group Policy is currently used and how the OUs are laid out. You do not have to redesign an already implemented OU structure in order to effectively deploy firewall and connection security policy, but an understanding of the structure helps you know what WMI or group filtering is required to apply each GPO to the correct devices. + +- **Existing IPsec policy**. Because this project culminates in the implementation of IPsec policy, you must understand how the network currently uses IPsec (if at all). Windows Firewall with Advanced Security connection security rules for versions of Windows prior to Windows Vista and Windows Server 2008 are not compatible with earlier versions of Windows.

An incomplete or inaccurate understanding of the network can prevent any Windows Firewall with Advanced Security solution from being successful. Understanding subnet layout, IP addressing schemes, and traffic patterns are part of this effort, but accurately documenting the following components are important to completing the planning phase of this project: + +- **Network segmentation**. This includes IP addressing maps, showing how your routers separate each network segment. It includes information about how the routers are configured, and what security filters they impose on network traffic flowing through them. + +- Network address translation (NAT). NAT is a means of separating network segments by using a device that maps all of the IP addresses on one side of the device to a single IP address accessible on the other side. + +- Network infrastructure devices. This includes the routers, switches, hubs, and other network equipment that makes communications between the devices on the network possible. + +- **Current network traffic model.** This includes the quantity and the characteristics of the network traffic flowing through your network. + +- Intrusion Detection System (IDS) devices. You will need to identify if you have any IDS devices on your network that might be negatively impacted by any encryption introduced in an Encryption Zone. + +The goal is to have enough information to be able to identify an asset by its network location, in addition to its physical location. + +Do not use a complex and poorly documented network as a starting point for the design, because it can leave too many unidentified areas that are likely to cause problems during implementation. + +This guidance helps obtain the most relevant information for planning Windows Firewall with Advanced Security implementation, but it does not try to address other issues, such as TCP/IP addressing or virtual local area network (VLAN) segmentation. + +## Network segmentation + + +If your organization does not have its current network architecture documented and available for reference, such documentation should be obtained as soon as possible before you continue with the design and deployment. If the documented information is not current or has not been validated recently, you have two options: + +- Accept that the lack of accurate information can cause risk to the project. + +- Undertake a discovery project, either through manual processes or with network analysis tools that can provide the information you need to document the current network topology. + +Although the required information can be presented in many different ways, a series of schematic diagrams is often the most effective method of illustrating and understanding the current network configuration. When creating network diagrams, do not include too much information. If necessary, use multiple diagrams that show different layers of detail. Use a top-level diagram that illustrates the major sites that make up your organization's network, and then break out each site into a more detailed diagram that captures a deeper level of detail. Continue until you reach the individual IP subnet level, and so have the means to identify the network location of every device in your organization. + +During this process, you might discover some network applications and services that are not compatible with IPsec. For example, IPsec breaks network-based prioritization and port/protocol-based traffic management. If traffic management or prioritization must be based on ports or protocol, the host itself must be able to perform any traffic management or prioritization. + +Other examples of incompatibility include: + +- Cisco NetFlow on routers cannot analyze packets between IPsec members based on protocol or port. + +- Router-based Quality of Service (QoS) cannot use ports or protocols to prioritize traffic. However, using firewall rules that specify IP addresses to prioritize traffic are not affected by this limitation of QoS. For example, a rule that says "From anyone to anyone using port 80 prioritize" does not work, but a rule that says "From anyone to 10.0.1.10 prioritize" works. + +- Weighted Fair Queuing and other flow-based router traffic priority methods might fail. + +- Devices that do not support or allow IP protocol 50, the port that is used by Encapsulating Security Payload (ESP). + +- Router access control lists (ACLs) cannot examine protocol and port fields in ESP-encrypted packets, and therefore the packets are dropped. ACLs based only on IP address are forwarded as usual. If the device cannot parse ESP, any ACLs that specify port or protocol rules will not be processed on the ESP packets. If the device has an ESP parser and uses encryption, ACLs that specify port or protocol rules will not be processed on the ESP packets. + +- Network monitoring tools might be unable to parse ESP packets that are not encrypted (ESP-Null). + + >**Note:**  Microsoft Message Analyzer can help in troubleshooting of unencrypted IPsec packets. The latest version of Message Analyzer is available on the [Microsoft Download Center](http://www.microsoft.com/download/details.aspx?id=44226). +   +## Network address translation (NAT) + +IPsec NAT traversal (NAT-T) enables IPsec peers that are behind NATs to detect the presence of NATs, negotiate IPsec security associations (SAs), and send ESP-protected data even though the addresses in the IPsec-protected IPv4 packets change. IPsec NAT-T does not support the use of AH across NAT devices. + +## Network infrastructure devices + +The devices that make up the network infrastructure (routers, switches, load balancers, and firewalls) must be able communicate using IPsec after the solution is implemented. For this reason, you have to examine the following characteristics of these network devices to ensure that they can handle the technical and physical requirements of the design: + +- **Make/model**. You can use this information to determine the features that the device supports. In addition, check the BIOS version or software running on the device to ensure that IPsec is supported. + +- **Amount of RAM**. This information is useful when you are analyzing capacity or the impact of IPsec on the device. + +- **Traffic analysis**. Information, such as peak usage and daily orweekly trends, is helpful to have. The information helps provide a baseline snapshot of the device and how it is used over time. If problems occur after IPsec is implemented, the information can help determine whether the root cause is related to greater usage of the device. + +- **Router ACLs that affect IPsec directly**. ACLs directly affect the ability of specific protocols to function. For example, blocking the Kerberos V5 protocol (UDP and TCP port 88) or IP protocol 50 or 51 prevents IPsec from working. Devices must also be configured to allow IKE traffic (UDP port 500) if using NAT-T (UDP port 4500). + +- **Networks/subnets connected to device interfaces**. This information provides the best picture of what the internal network looks like. Defining the boundary of subnets based on an address range is straightforward and helps identify whether other addresses are either unmanaged or foreign to the internal network (such as IP addresses on the Internet). + +- **VLAN segmentation**. Determining how VLANs are implemented on the network can help you understand traffic patterns and security requirements, and then help to determine how IPsec might augment or interfere with these requirements. + +- **The maximum transmission unit (MTU) size on device interface(s)**. The MTU defines the largest datagram that can be transmitted on a particular interface without being divided into smaller pieces for transmission (a process also known as *fragmentation*). In IPsec communications, the MTU is necessary to anticipate when fragmentation occurs. Packet fragmentation must be tracked for Internet Security Association and Key Management Protocol (ISAKMP) by the router. IPsec configures the MTU size on the session to the minimum-discovered MTU size along the communication path being used, and then set the Don't Fragment bit (DF bit) to 1. + + >**Note:**  If Path MTU (PMTU) discovery is enabled and functioning correctly, you do not have to gather the MTU size on device interfaces. Although sources, such as the Windows Server 2003 Hardening Guide, recommend disabling PMTU discovery, it must be enabled for IPsec to function correctly. + +- **Intrusion detection system (IDS) in use**. Your IDS must have an IPsec-compatible parser to detect ESP packets. If the IDS does not have such a parser, it cannot determine if data in those packets is encrypted. + +After you obtain this information, you can quickly determine whether you must upgrade the devices to support the requirements of the project, change the ACLs, or take other measures to ensure that the devices can handle the loads needed. + +## Current network traffic model + +After gathering the addressing and network infrastructure information, the next step is to examine the communications flow. For example, if a department such as Human Resources (HR) spans several buildings, and you want to use server isolation with encryption to help protect information in that department, you must know how those buildings are connected to determine the level of "trust" to place in the connection. A highly secured building that is connected by an unprotected cable to another building that is not secured can be compromised by an eavesdropping or information replay attack. If such an attack is considered a threat, IPsec can help by providing strong mutual authentication and traffic encryption for trusted hosts. IPsec allows you to more securely communicate across untrusted links such as the Internet. + +When you examine traffic flow, look closely at how all managed and unmanaged devices interact. This includes non-Windows-based devices running Linux, UNIX, and Macintosh. Ask yourself such questions as: + +- Do specific communications occur at the port and protocol level, or are there many sessions between the same hosts across many protocols? + +- How do servers and clients communicate with each other? + +- Are there security devices or projects currently implemented or planned that could affect an isolation deployment? For example, if you use Windows Firewall on your devices to "lock down" specific ports, such as UDP 500, IKE negotiations fail. + +Some of the more common applications and protocols are as follows: + +- **NetBIOS over TCP/IP (NetBT) and server message block (SMB)**. On a LAN, it is common to have ports 137, 138, and 139 enabled for NetBT and port 445 enabled for SMB. These ports provide NetBIOS name resolution services and other features. Unfortunately, they also allow the creation of *null sessions*. A null session is a session that is established on a host that does not use the security context of a known user or entity. Frequently, these sessions are anonymous. + +- **Remote procedure call (RPC)**. RPC operates by listening on a port known as the *endpoint mapper*, TCP port 135. The response to a query on this port is an instruction to begin communication on another port in the ephemeral range (ports numbered over 1024). In a network that is segmented by firewalls, RPC communication presents a configuration challenge because it means opening the RPC listener port and all ports greater than 1024. Opening so many ports increases the attack surface of the whole network and reduces the effectiveness of the firewalls. Because many applications depend on RPC for basic functionality, any firewall and connection security policy must take RPC requirements into account. + +- **Other traffic**. Windows Firewall with Advanced Security can help secure transmissions between devices by providing authentication of the packets in addition to encrypting the data that they contain. The important thing to do is to identify what must be protected, and the threats that must be mitigated. Examine and model other traffic or traffic types that must be secured. + +**Next: **[Gathering Information about Your Active Directory Deployment](gathering-information-about-your-active-directory-deployment.md) diff --git a/windows/keep-secure/gathering-information-about-your-devices.md b/windows/keep-secure/gathering-information-about-your-devices.md new file mode 100644 index 0000000000..1f3b73fa21 --- /dev/null +++ b/windows/keep-secure/gathering-information-about-your-devices.md @@ -0,0 +1,54 @@ +--- +title: Gathering Information about Your Devices (Windows 10) +description: Gathering Information about Your Devices +ms.assetid: 7f7cd3b9-de8e-4fbf-89c6-3d1a47bc2beb +ms.prod: w10 +ms.mktglfcycl: deploy +ms.sitesec: library +ms.pagetype: security +author: brianlic-msft +--- + +# Gathering Information about Your Devices + +**Applies to** +- Windows 10 +- Windows Server 2016 Technical Preview + +One of the most valuable benefits of conducting an asset discovery project is the large amount of data that is obtained about the client and server devices on the network.

This name is the device's NetBIOS or DNS name that identifies the device on the network.

It is also important to track the current state of service packs and updates that might be installed, because these are often used to determine that minimum security standards have been met. + +- **Domain membership**. This information is used to determine whether a device can obtain IPsec policy from Active Directory or whether it must use a local IPsec policy. + +- **Physical location**. This information is just the location of the device in your organization. It can be used to determine whether a device can participate in a specific isolation group based on its location or the location of the devices that it communicates with regularly. + +- **Hardware type or role**.

Areas to watch: + +- **Encryption.** You might use 256-bit Advanced Encryption Standard (AES-256) and 384-bit Secure Hash Algorithm (SHA-384) to check integrity in situations that require the strongest available encryption and key exchange protection. If you have NICs that support IPsec Task Offload, you can reduce the effect that encryption has on network throughput. For more information, see [IPsec Task Offload](http://technet.microsoft.com/network/dd277647.aspx). + +- **Security association (SA) negotiation.** You can use a shorter lifetime for the main mode SA, such as three hours, but then you might need to make tradeoffs. Because each main mode SA occupies approximately 5  KB of RAM, situations in which a server brokers tens of thousands of concurrent connections can lead to overutilization. + +- **NAT devices.** As discussed earlier, NAT does not allow Authentication Header (AH) conversations between hosts. If NAT devices exist on the internal network, ESP must be selected instead of AH. + +- **Switches and routers.** Proper capacity planning for the implementation of IPsec is more about thorough testing and expected traffic loads than exact calculations. You might have to upgrade or reconfigure switches or routers that currently exceed 75 percent usage to allow for increased traffic on the device and still provide some extra usage for bursts of traffic. + +- **Other factors.** These include CPU usage on network infrastructure servers, increased overhead on servers and workstations running IPsec (especially servers, because they usually contain more main mode SAs than clients), and increased network latency because of IPsec negotiation. + + >**Note:**  When Microsoft deployed its own domain isolation solution, it found a one to three percent increase in usage on the network as a direct result of IPsec. + +## Group Policy deployment groups and WMI filters + +You do not have to rearrange the organization unit (OU) hierarchy of your Active Directory domains to effectively deploy Windows Firewall with Advanced Security GPOs. Instead, you can link your GPOs at the domain level (or another high level container), and then use security group filtering or WMI filtering to ensure that only the appropriate devices or users can apply the GPO settings. We recommend that you use WMI filtering to dynamically ensure that GPOs apply only to devices that are running the correct operating system. It is not necessary to use this technique if your network consists of devices. + +## Different Active Directory trust environments + +When you design a domain isolation policy, consider any logical boundaries that might affect IPsec-secured communications. For example, the trust relationships between your domains and forests are critical in determining an appropriate IKE authentication method. + +Kerberos V5 authentication is recommended for use in a two-way (mutual) domain and forest trust environment. You can use Kerberos V5 for IKE authentication across domains that have two-way trusts established, if the domains are in the same forest or different forests. If the two domains are in different forests, you must configure two external trusts, one for each direction, between the domains. The external trusts must use the fully qualified domain name (FQDN) of the domains, and IPsec policy must allow an IKE initiator in one domain to communicate with any domain controller in the forest domain hierarchy, so that the initiator can obtain a Kerberos V5 ticket from a domain controller in the responder’s domain. If firewalls separate the domains then you must configure the firewall to allow Kerberos V5 traffic over UDP destination port 88, TCP destination port 88, and UDP destination port 389. + +If the use of Kerberos V5 authentication is not possible because two-way trusts across forests cannot be established as in some large enterprise environments, you can use a public key infrastructure (PKI) and digital certificates to establish IPsec-trusted communication. + +## Creating firewall rules to permit IKE, AH, and ESP traffic + + +In some cases, IPsec-secured traffic might have to pass through a router, perimeter firewall, or other filtering device. In the case of a router, unless the router filters TCP and UDP traffic or other upper-level protocol headers, no special configuration is required to allow the IPsec traffic to be forwarded. + +In the case of a filtering router or a firewall, you must configure these devices to allow IPsec traffic to be forwarded. Configure the firewall to allow IPsec traffic on UDP source and destination port 500 (IKE), UDP source and destination port 4500 (IPsec NAT-T), and IP Protocol 50 (ESP). You might also have to configure the firewall to allow IPsec traffic on IP protocol 51 (AH) to allow troubleshooting by IPsec administrators and to allow the IPsec traffic to be inspected. + +For more info, see [How to Enable IPsec Traffic Through a Firewall](http://go.microsoft.com/fwlink/?LinkId=45085). + +## Network load balancing and server clusters + +There are challenges implementing connection security for network traffic going to and from network load balancing (NLB) clusters and server clusters. NLB enables multiple servers to be clustered together to provide high availability for a service by providing automatic failover to other nodes in the cluster. Because IPsec matches a security association to a specific device, it prevents different devices from handling the same client connection. If a different node in the cluster responds to an IPsec connection that was originally established by another node, the traffic will be dropped by the client device as untrusted. + +This means that NLB in "no affinity" mode is not supported by IPsec at all. If you must use "no affinity" mode in the cluster then consider including the servers that make up the cluster in your IPsec exemption group, and allowing clients to communicate with the servers without IPsec. + +When a TCP connection is dropped because of a cluster node failover, IPsec detects the TCP connection failure and removes the IPsec SAs for that connection. When the new TCP connection is established to another node, IPsec can negotiate new SAs immediately without having to wait for the obsolete SAs to time out. + +## Network inspection technologies + +Within a TCP/IP packet, IPsec without encryption changes the offsets for the destination ports and protocols. These changes can adversely affect applications that are running on network devices such as routers that monitor and manage traffic on the network. While some network applications have been updated to support IPsec, some are not yet compatible. Check with the vendor of your device to see whether the changes in the protocol and port fields caused by IPsec are compatible with the device. + +Any device designed to view network traffic, such as hardware protocol analyzers or Microsoft Network Monitor, cannot parse ESP-encrypted traffic. Only the destination device, with which the originating device negotiated the connection, can decrypt the traffic. + +In general, IPsec defeats network-based prioritization and port- or protocol-based traffic management. For encrypted packets, there is no workaround; the host itself must handle any traffic management functions. For unencrypted, authenticated-only packets, the devices and applications must be aware of how IPsec changes packets to be able to do anything with them other than route them to the correct host. If you cannot upgrade monitoring or management devices to support IPsec, it is important that you record this information and figure it into your domain or server isolation design. + +Network Monitor includes parsers for the ISAKMP (IKE), AH, and ESP protocols. Network Monitor parsers for ESP can parse inside the ESP packet only if ESP null-encryption is being used. Network Monitor cannot parse the encrypted parts of IPsec ESP traffic when encryption is performed in software. However, if encryption is performed by an IPsec hardware offload network adapter, the ESP packets can be decrypted when Network Monitor captures them on either the source or the destination and, therefore, they can be parsed.

Preview + +The following are important factors in the implementation of your Windows Firewall with Advanced Security design plan: + +- **Group Policy**. The Windows Firewall with Advanced Security designs make extensive use of Group Policy deployed by Active Directory Domain Services (AD DS). A sound Group Policy infrastructure is required to successfully deploy the firewall and IPsec settings and rules to the devices on your network. + +- **Perimeter firewall**. Most organizations use a perimeter firewall to help protect the devices on the network from potentially malicious network traffic from outside of the organization's network boundaries. If you plan a deployment that includes a boundary zone to enable external devices to connect to devices in that zone, then you must allow that traffic through the perimeter firewall to the devices in the boundary zone. + +- **Devices running operating systems other than Windows**. If your network includes devices that are not running the Windows operating system, then you must make sure that required communication with those devices is not blocked by the restrictions put in place by your design. You must do one of the following: + + - Include those devices in the isolated domain or zone by adding certificate-based authentication to your design. Many other operating systems can participate in an isolated domain or isolated server scenario, as long as certificate-based authentication is used. + + - Include the device in the authentication exemption list included in your design. You can choose this option if for any reason the device cannot participate in the isolated domain design. + +## How to implement your Windows Firewall with Advanced Security design using this guide + + +The next step in implementing your design is to determine in what order each of the deployment steps must be performed. This guide uses checklists to help you accomplish the various deployment tasks that are required to implement your design plan. As the following diagram shows, checklists and subchecklists are used as necessary to provide the end-to-end procedure for deploying a design. + +![wfas implementation](images/wfas-implement.gif) + +Use the following parent checklists in this section of the guide to become familiar with the deployment tasks for implementing your organization's Windows Firewall with Advanced Security design. + +- [Checklist: Implementing a Basic Firewall Policy Design](checklist-implementing-a-basic-firewall-policy-design.md) + +- [Checklist: Implementing a Domain Isolation Policy Design](checklist-implementing-a-domain-isolation-policy-design.md) + +- [Checklist: Implementing a Domain Isolation Policy Design](checklist-implementing-a-domain-isolation-policy-design.md) + +- [Checklist: Implementing a Certificate-based Isolation Policy Design](checklist-implementing-a-certificate-based-isolation-policy-design.md) + +The procedures in these checklists use the Group Policy MMC snap-in interfaces to configure firewall and connection security rules in GPOs, but you can also use Windows PowerShell. For more information, see [Windows Firewall with Advanced Security Administration with Windows PowerShell](windows-firewall-with-advanced-security-administration-with-windows-powershell.md). This guide recommends using GPOs in a specific way to deploy the rules and settings for your design.

The devices in this zone use connection security and firewall rules to control the communications that can be sent between devices in the zone. + +The term *domain* in this context means a boundary of communications trust instead of an Active Directory domain. In this solution the two constructs are very similar because Active Directory domain authentication (Kerberos V5) is required for accepting inbound connections from trusted devices. However, many Active Directory domains (or forests) can be linked with trust relationships to provide a single, logical, isolated domain. In addition, devices that authenticate by using certificates can also be included in an isolated domain without joining the Active Directory domain. + +For most implementations, an isolated domain will contain the largest number of devices. Other isolation zones can be created for the solution if their communication requirements differ from those of the isolated domain. Examples of these differences are what result in the boundary and encryption zones described in this guide. Conceptually, the isolated domain is just the largest isolation zone, and a superset to the other zones. + +You must create a group in Active Directory to contain members of the isolated domain.

We recommend that you do not include DES, or MD5 in any setting. They are included only for compatibility with previous versions of Windows. Use the strongest algorithm combinations that are common to all your supported operating systems. + + If any NAT devices are present on your networks, use ESP encapsulation. If isolated domain members must communicate with hosts in the encryption zone, ensure that you include algorithms that are compatible with the requirements of the encryption mode policies. + + 4. Authentication methods. Include at least device-based Kerberos V5 authentication. If you want to use user-based access to isolated servers, then also include user-based Kerberos V5 as an optional authentication method.

Developers who build Windows Store apps can declare certain app capabilities that enable different classes of network access. A developer can decide what kind of network access the app requires and configure this capability for the app. When the app is installed on a device, appropriate firewall rules are automatically created to enable access. You can then customize the firewall configuration to further fine-tune this access if they desire more control over the network access for the app. + +For example, a developer can decide that their app should only connect to trusted local networks (such as at home or work), and not to the Internet. In this way, developers can define the scope of network access for their app. This network isolation prevents an app from accessing a network and a connection type (inbound or outbound) if the connection has not been configured for the app. Then the network administrator can customize the firewall to further restrict the resources that the app can access. + +The ability to set and enforce these network boundaries ensures that apps that get compromised can only access networks where they have been explicitly granted access. This significantly reduces the scope of their impact on other apps, the device, and the network. In addition, apps can be isolated and protected from malicious access from the network. + +When creating new Windows Store apps, a developer can define the following network capabilities for their app: + +- **Home\\Work Networking** + + Provides inbound and outbound access to intranet networks that the user has designated as a home or a work network, or if the network has an authenticated domain controller. + +- **Internet (Client)** + + Provides outbound access to the Internet and untrusted networks, such as airports and coffee shops (for example, intranet networks where the user has designated the network as Public).

The firewall rules can be configured for any of the network location profiles that you see in the Network and Sharing Center: **Domain**, **Public**, and **Private**. Most settings are enforced in the Domain profile, without an option for the user to change them. However, you might want to leave the profile settings configurable by the user on devices that can be taken from the organization's physical network and joined to a public or home network. If you lock down the public and private profiles, you might prevent a user from accessing a required network program or service. Because they are not on the organization's network, you cannot fix a connectivity problem by deploying rule changes in a GPO. For each section that follows, consider each profile and apply the rules to those profiles that make sense for your organization. + + >**Important:**  We recommend that on server devices that you set all rules for all profiles to prevent any unexpected profile switch from disrupting network connectivity. You might consider a similar practice for your desktop devices, and only support different profiles on portable devices. + +- **Firewall state: On**. We recommend that you prevent the user from turning it off. + +- **Default behavior for Inbound connections: Block**. We recommend that you enforce the default behavior of blocking unsolicited inbound connections. To allow network traffic for a specific program, create an inbound rule that serves as an exception to this default behavior. + +- **Default behavior for Outbound connections: Allow**. We recommend that you enforce the default behavior of allowing outbound connections. + +- **Allow unicast response: Yes**. We recommend that you use the default setting of **Yes** unless you have specific requirements to do otherwise. + +- **Apply local firewall rules: Yes**. We recommend that you allow users to create and use local firewall rules. If you set this to **No**, then when a user clicks **Allow** on the notification message to allow traffic for a new program, Windows does not create a new firewall rule and the traffic remains blocked. + + If you and the IT staff can create and maintain the list of firewall rules for all permitted applications and deploy them by using GPOs then you can set this value to **No**. + +- **Apply local connection security rules: No**. We recommend that you prevent users from creating and using their own connection security rules. Connection failures caused by conflicting rules can be difficult to troubleshoot. + +- **Logging**. We recommend that you enable logging to a file on the local hard disk. Be sure to limit the size, such as 4096 KB, to avoid causing performance problems by filling the user's hard disk. Be sure to specify a folder to which the Windows Firewall service account has write permissions. + +- **Inbound rules**. Create inbound rules for programs that must be able to receive unsolicited inbound network packets from another device on the network. Make the rules as specific as possible to reduce the risk of malicious programs exploiting the rules. For example, specify both program and port numbers. Specifying a program ensures that the rule is only active when the program is actually running, and specifying the port number ensures that the program cannot receive unexpected traffic on a different port. + + Inbound rules are common on servers, because they host services to which client devices connect. When you install programs and services on a server, the installation program typically creates and enables the rules for you. Examine the rules to ensure that they do not open up more ports than are required. + + >**Important:**  If you create inbound rules that permit RPC network traffic by using the **RPC Endpoint Mapper** and **Dynamic RPC** rule options, then all inbound RPC network traffic is permitted because the firewall cannot filter network traffic based on the UUID of the destination application. + +- **Outbound rules**. Only create outbound rules to block network traffic that must be prevented in all cases. If your organization prohibits the use of certain network programs, you can support that policy by blocking the known network traffic used by the program. Be sure to test the restrictions before you deploy them to avoid interfering with traffic for needed and authorized programs. + +**Next: **[Planning Domain Isolation Zones](planning-domain-isolation-zones.md) diff --git a/windows/keep-secure/planning-the-gpos.md b/windows/keep-secure/planning-the-gpos.md new file mode 100644 index 0000000000..b22f0497cd --- /dev/null +++ b/windows/keep-secure/planning-the-gpos.md @@ -0,0 +1,55 @@ +--- +title: Planning the GPOs (Windows 10) +description: Planning the GPOs +ms.assetid: 11949ca3-a11c-4a16-b297-0862432eb5b4 +ms.prod: w10 +ms.mktglfcycl: deploy +ms.sitesec: library +ms.pagetype: security +author: brianlic-msft +--- + +# Planning the GPOs + +**Applies to** +- Windows 10 +- Windows Server 2016 Technical Preview + +When you plan the GPOs for your different isolation zones, you must complete the layout of the required zones and their mappings to the groups that link the devices to the zones. + +## General considerations + +A few things to consider as you plan the GPOs: + +- Do not allow a device to be a member of more than one isolation zone. A device in more than one zone receives multiple and possibly contradictory GPOs. This can result in unexpected, and difficult to troubleshoot behavior. + + The examples in this guide show GPOs that are designed to prevent the requirement to belong to multiple zones. + +- Ensure that the IPsec algorithms you specify in your GPOs are compatible across all the versions of Windows. The same principle applies to the data integrity and encryption algorithms. We recommend that you include the more advanced algorithms when you have the option of selecting several in an ordered list. The devices will negotiate down from the top of their lists, selecting one that is configured on both devices. + +- The primary difference in your domain isolation GPOs is whether the rules request or require authentication. + + >**Caution:**  It is **critical** that you begin with all your GPOs set to request authentication instead of requiring it. Since the GPOs are delivered to the devices over time, applying a require policy to one device breaks its ability to communicate with another device that has not yet received its policy. Using request mode at the beginning enables devices to continue communicating by using plaintext connections if required. After you confirm that your devices are using IPsec where expected, you can schedule a conversion of the rules in the GPOs from requesting to requiring authentication, as required by each zone. + +- Windows Firewall with Advanced Security in Windows Vista and Windows Server 2008 only support one network location profile at a time. If you add a second network adapter that is connected to a different network, or not connected at all, you could unintentionally change the profile that is currently active on the device. If your GPO specifies different firewall and connection security rules based on the current network location profile, the behavior of how the device handles network traffic will change accordingly. We recommend for stationary devices, such as desktops and servers, that you assign any rule for the device to all profiles. Apply GPOs that change rules per network location to devices that must move between networks, such as your portable devices. Consider creating a separate domain isolation GPO for your servers that uses the same settings as the GPO for the clients, except that the server GPO specifies the same rules for all network location profiles. + + >**Note:**  Devices running Windows 7, Windows Server 2008 R2, and later support different network location types, and therefore profiles, for each network adapter at the same time. Each network adapter is assigned the network location appropriate for the network to which it is connected. Windows Firewall then enforces only those rules that apply to that network type’s profile. So certain types of traffic are blocked when coming from a network adapter connected to a public network, but those same types might be permitted when coming from a private or domain network. + +After considering these issues, document each GPO that you require, and the details about the connection security and firewall rules that it needs. + +## Woodgrove Bank example GPOs + + +The Woodgrove Bank example uses the following set of GPOs to support its domain isolation requirements.

The mathematically intensive cryptographic algorithms require a significant amount of computing power, which can prevent your device from making use of all of the available bandwidth. For example, an IPsec-enabled device using the AES encryption protocols on a 10 gigabits per second (Gbps) network link might see a throughput of 4.5 Gbps. This is due to the demands placed on the CPU to perform the cryptographic functions required by the IPsec integrity and encryption algorithms. + +IPsec task offload is a Windows technology that supports network adapters equipped with dedicated cryptographic processors to perform the computationally intensive work required by IPsec.

For example, you can make the boundary group a member of the isolated domain group, so that it receives the firewall and basic isolated domain settings through that nested membership, with only the changes supplied by the boundary zone GPO. However, devices that are running older versions of Windows can only support a single IPsec policy being active at a time. The policies for each GPO must be complete (and to a great extent redundant with each other), because you cannot layer them as you can in the newer versions of Windows. For simplicity, this guide describes the techniques used to create the independent, non-layered policies. We recommend that you create and periodically run a script that compares the memberships of the groups that must be mutually exclusive and reports any devices that are incorrectly assigned to more than one group. + +  +Network access groups (NAGs) are not used to determine which GPOs are applied to a computer.

For this design, you then create zones for servers that have additional security requirements. The zones can limit access to the server to only members of authorized groups, and can optionally require the encryption of all traffic in or out of these servers. This can be done on a per server basis, or for a group of servers that share common security requirements. + +You can implement a server isolation design without using domain isolation. To do this, you use the same principles as domain isolation, but instead of applying them to an Active Directory domain, you apply them only to the devices that must be able to access the isolated servers. The GPO contains connection security and firewall rules that require authentication when communicating with the isolated servers. In this case, the NAGs that determine which users and devices can access the isolated server are also used to determine which devices receive the GPO. + +The design is shown in the following illustration, with arrows that show the permitted communication paths. + +![isolated domain with isolated server](images/wfas-domainisohighsec.gif) + +Characteristics of this design include the following: + +- Isolated domain (area A) - The same isolated domain described in the [Domain Isolation Policy Design](domain-isolation-policy-design.md) section.

Encryption zones are most often implemented as rules that are part of a server isolation zone, instead of as a separate zone. The diagram illustrates the concept as a subset for conceptual purposes only. + +To add support for server isolation, you must ensure that the authentication methods are compatible with the requirements of the isolated server.

This firewall rule is scoped to the local subnet by using a keyword instead of an IP address. Just like in Netsh, the rule is created on the local device, and it becomes effective immediately. + +**Netsh** + +``` syntax +netsh advfirewall firewall add rule name="Allow Inbound Telnet" dir=in program= %SystemRoot%\System32\tlntsvr.exe remoteip=localsubnet action=allow +``` + +Windows PowerShell + +``` syntax +New-NetFirewallRule -DisplayName “Allow Inbound Telnet” -Direction Inbound -Program %SystemRoot%\System32\tlntsvr.exe -RemoteAddress LocalSubnet -Action Allow +``` + +The following scriptlet shows how to add a basic firewall rule that blocks outbound traffic from a specific application and local port to a Group Policy Object (GPO) in Active Directory. In Windows PowerShell, the policy store is specified as a parameter within the **New-NetFirewall** cmdlet. In Netsh, you must first specify the GPO that the commands in a Netsh session should modify. The commands you enter are run against the contents of the GPO, and this remains in effect until the Netsh session is ended or until another set store command is executed. + +Here, **domain.contoso.com** is the name of your Active Directory Domain Services (AD DS), and **gpo\_name** is the name of the GPO that you want to modify. Quotation marks are required if there are any spaces in the GPO name. + +**Netsh** + +``` syntax +netsh advfirewall set store gpo=domain.contoso.com\gpo_name +netsh advfirewall firewall add rule name="Block Outbound Telnet" dir=out program=%SystemRoot%\System32\telnet.exe protocol=tcp localport=23 action=block +``` + +Windows PowerShell + +``` syntax +New-NetFirewallRule -DisplayName “Block Outbound Telnet” -Direction Outbound -Program %SystemRoot%\System32\tlntsvr.exe –Protocol TCP –LocalPort 23 -Action Block –PolicyStore domain.contoso.com\gpo_name +``` + +### GPO Caching + +To reduce the burden on busy domain controllers, Windows PowerShell allows you to load a GPO to your local session, make all your changes in that session, and then save it back at all once. + +The following performs the same actions as the previous example (by adding a Telnet rule to a GPO), but we do so leveraging GPO caching in PowerShell. Changing the GPO by loading it onto your local session and using the *-GPOSession* parameter are not supported in Netsh + +Windows PowerShell + +``` syntax +$gpo = Open-NetGPO –PolicyStore domain.contoso.com\gpo_name +New-NetFirewallRule -DisplayName “Block Outbound Telnet” -Direction Outbound -Program %SystemRoot%\System32\telnet.exe –Protocol TCP –LocalPort 23 -Action Block –GPOSession $gpo +Save-NetGPO –GPOSession $gpo +``` + +Note that this does not batch your individual changes, it loads and saves the entire GPO at once. So if any other changes are made by other administrators, or in a different Windows PowerShell window, saving the GPO overwrites those changes. + +### Modify an existing firewall rule + +When a rule is created, Netsh and Windows PowerShell allow you to change rule properties and influence, but the rule maintains its unique identifier (in Windows PowerShell this is specified with the *-Name* parameter). + +For example, you could have a rule **Allow Web 80** that enables TCP port 80 for inbound unsolicited traffic. You can change the rule to match a different remote IP address of a Web server whose traffic will be allowed by specifying the human-readable, localized name of the rule. + +**Netsh** + +``` syntax +netsh advfirewall firewall set rule name="Allow Web 80" new remoteip=192.168.0.2 +``` + +Windows PowerShell + +``` syntax +Set-NetFirewallRule –DisplayName “Allow Web 80” -RemoteAddress 192.168.0.2 +``` + +Netsh requires you to provide the name of the rule for it to be changed and we do not have an alternate way of getting the firewall rule. In Windows PowerShell, you can query for the rule using its known properties. + +When you run `Get-NetFirewallRule`, you may notice that common conditions like addresses and ports do not appear. These conditions are represented in separate objects called Filters. As shown before, you can set all the conditions in New-NetFirewallRule and Set-NetFirewallRule. If you want to query for firewall rules based on these fields (ports, addresses, security, interfaces, services), you will need to get the filter objects themselves. + +You can change the remote endpoint of the **Allow Web 80** rule (as done previously) using filter objects. Using Windows PowerShell you query by port using the port filter, then assuming additional rules exist affecting the local port, you build with further queries until your desired rule is retrieved. + +In the following example, we assume the query returns a single firewall rule, which is then piped to the `Set-NetFirewallRule` cmdlet utilizing Windows PowerShell’s ability to pipeline inputs. + +Windows PowerShell + +``` syntax +Get-NetFirewallPortFilter | ?{$_.LocalPort -eq 80} | Get-NetFirewallRule | ?{ $_.Direction –eq “Inbound” -and $_.Action –eq “Allow”} | Set-NetFirewallRule -RemoteAddress 192.168.0.2 +``` + +You can also query for rules using the wildcard character. The following example returns an array of firewall rules associated with a particular program. The elements of the array can be modified in subsequent `Set-NetFirewallRule` cmdlets. + +Windows PowerShell + +``` syntax +Get-NetFirewallApplicationFilter -Program "*svchost*" | Get-NetFirewallRule +``` + +Multiple rules in a group can be simultaneously modified when the associated group name is specified in a Set command. You can add firewall rules to specified management groups in order to manage multiple rules that share the same influences. + +In the following example, we add both inbound and outbound Telnet firewall rules to the group **Telnet Management**. In Windows PowerShell, group membership is specified when the rules are first created so we re-create the previous example rules. Adding rules to a custom rule group is not possible in Netsh. + +Windows PowerShell + +``` syntax +New-NetFirewallRule -DisplayName “Allow Inbound Telnet” -Direction Inbound -Program %SystemRoot%\System32\tlntsvr.exe -RemoteAddress LocalSubnet -Action Allow –Group “Telnet Management” +New-NetFirewallRule -DisplayName “Block Outbound Telnet” -Direction Inbound -Program %SystemRoot%\System32\tlntsvr.exe -RemoteAddress LocalSubnet -Action Allow –Group “Telnet Management” +``` + +If the group is not specified at rule creation time, the rule can be added to the rule group using dot notation in Windows PowerShell. You cannot specify the group using `Set-NetFirewallRule` since the command allows querying by rule group. + +Windows PowerShell + +``` syntax +$rule = Get-NetFirewallRule -DisplayName “Allow Inbound Telnet” +$rule.Group = “Telnet Management” +$rule | Set-NetFirewallRule +``` + +Using the `Set` command, if the rule group name is specified, the group membership is not modified but rather all rules of the group receive the same modifications indicated by the given parameters. + +The following scriptlet enables all rules in a predefined group containing remote management influencing firewall rules. + +**Netsh** + +``` syntax +netsh advfirewall firewall set rule group="windows firewall remote management" new enable=yes +``` + +Windows PowerShell + +``` syntax +Set-NetFirewallRule -DisplayGroup “Windows Firewall Remote Management” –Enabled True +``` + +There is also a separate `Enable-NetFirewallRule` cmdlet for enabling rules by group or by other properties of the rule. + +Windows PowerShell + +``` syntax +Enable-NetFirewallRule -DisplayGroup “Windows Firewall Remote Management” -Verbose +``` + +### Delete a firewall rule + +Rule objects can be disabled so that they are no longer active. In Windows PowerShell, the **Disable-NetFirewallRule** cmdlet will leave the rule on the system, but put it in a disabled state so the rule no longer is applied and impacts traffic. A disabled firewall rule can be re-enabled by **Enable-NetFirewallRule**. This is different from the **Remove-NetFirewallRule**, which permanently removes the rule definition from the device. + +The following cmdlet deletes the specified existing firewall rule from the local policy store. + +**Netsh** + +``` syntax +netsh advfirewall firewall delete rule name=“Allow Web 80” +``` + +Windows PowerShell + +``` syntax +Remove-NetFirewallRule –DisplayName “Allow Web 80” +``` + +Like with other cmdlets, you can also query for rules to be removed. Here, all blocking firewall rules are deleted from the device. + +Windows PowerShell + +``` syntax +Remove-NetFirewallRule –Action Block +``` + +Note that it may be safer to query the rules with the **Get** command and save it in a variable, observe the rules to be affected, then pipe them to the **Remove** command, just as we did for the **Set** commands. The following example shows how you can view all the blocking firewall rules, and then delete the first four rules. + +Windows PowerShell + +``` syntax +$x = Get-NetFirewallRule –Action Block +$x +$x[0-3] | Remove-NetFirewallRule +``` + +## Manage remotely + +Remote management using WinRM is enabled by default. The cmdlets that support the *CimSession* parameter use WinRM and can be managed remotely by default. + +The following example returns all firewall rules of the persistent store on a device named **RemoteDevice**. + +Windows PowerShell + +``` syntax +Get-NetFirewallRule –CimSession RemoteDevice +``` + +We can perform any modifications or view rules on remote devices by simply using the *–CimSession* parameter. Here we remove a specific firewall rule from a remote device. + +Windows PowerShell + +``` syntax +$RemoteSession = New-CimSession –ComputerName RemoteDevice +Remove-NetFirewallRule –DisplayName “AllowWeb80” –CimSession $RemoteSession -Confirm +``` + +## Deploy basic IPsec rule settings + +An Internet Protocol security (IPsec) policy consists of rules that determine IPsec behavior. IPsec supports network-level peer authentication, data origin authentication, data integrity, data confidentiality (encryption), and replay protection. + +Windows PowerShell can create powerful, complex IPsec policies like in Netsh and the Windows Firewall with Advanced Security console. However, because Windows PowerShell is object-based rather than string token-based, configuration in Windows PowerShell offers greater control and flexibility. + +In Netsh, the authentication and cryptographic sets were specified as a list of comma-separated tokens in a specific format. In Windows PowerShell, rather than using default settings, you first create your desired authentication or cryptographic proposal objects and bundle them into lists in your preferred order. Then, you create one or more IPsec rules that reference these sets. The benefit of this model is that programmatic access to the information in the rules is much easier. See the following sections for clarifying examples. + +![object model for creating a single ipsec rule](images/createipsecrule.gif) + +### Create IPsec rules + +The following cmdlet creates basic IPsec transport mode rule in a Group Policy Object. An IPsec rule is simple to create; all that is required is the display name, and the remaining properties use default values.

Note that there is no need to copy associated firewall filters. You can query rules to be copied in the same way as other cmdlets. + +Copying individual rules is a task that is not possible through the Netsh interface. Here is how you can accomplish it with Windows PowerShell. + +Windows PowerShell + +``` syntax +$Rule = Get-NetIPsecRule –DisplayName “Require Inbound Authentication” +$Rule | Copy-NetIPsecRule –NewPolicyStore domain.costoso.com\new_gpo_name +$Rule | Copy-NetPhase1AuthSet –NewPolicyStore domain.costoso.com\new_gpo_name +``` + +### Handling Windows PowerShell errors + +To handle errors in your Windows PowerShell scripts, you can use the *–ErrorAction* parameter. This is especially useful with the **Remove** cmdlets. If you want to remove a particular rule, you will notice that it fails if the rule is not found. When removing rules, if the rule isn’t already there, it is generally acceptable to ignore that error. In this case, you can do the following to suppress any “rule not found” errors during the remove operation. + +Windows PowerShell + +``` syntax +Remove-NetFirewallRule –DisplayName “Contoso Messenger 98” –ErrorAction SilentlyContinue +``` + +Note that the use of wildcards can also suppress errors, but they could potentially match rules that you did not intend to remove. This can be a useful shortcut, but should only be used if you know there aren’t any extra rules that will be accidentally deleted. So the following cmdlet will also remove the rule, suppressing any “not found” errors. + +Windows PowerShell + +``` syntax +Remove-NetFirewallRule –DisplayName “Contoso Messenger 98*” +``` + +When using wildcards, if you want to double-check the set of rules that is matched, you can use the *–WhatIf* parameter. + +Windows PowerShell + +``` syntax +Remove-NetFirewallRule –DisplayName “Contoso Messenger 98*” –WhatIf +``` + +If you only want to delete some of the matched rules, you can use the *–Confirm* parameter to get a rule-by-rule confirmation prompt. + +Windows PowerShell + +``` syntax +Remove-NetFirewallRule –DisplayName “Contoso Messenger 98*” –Confirm +``` + +You can also just perform the whole operation, displaying the name of each rule as the operation is performed. + +Windows PowerShell + +``` syntax +Remove-NetFirewallRule –DisplayName “Contoso Messenger 98*” –Verbose +``` + +### Monitor + +The following Windows PowerShell commands are useful in the update cycle of a deployment phase. + +To allow you to view all the IPsec rules in a particular store, you can use the following commands. In Netsh, this command does not show rules where profile=domain,public or profile=domain,private. It only shows rules that have the single entry domain that is included in the rule. The following command examples will show the IPsec rules in all profiles. + +**Netsh** + +``` syntax +netsh advfirewall consec show rule name=all +``` + +Windows PowerShell + +``` syntax +Show-NetIPsecRule –PolicyStore ActiveStore +``` + +You can monitor main mode security associations for information such as which peers are currently connected to the device and which protection suite is used to form the security associations. + +Use the following cmdlet to view existing main mode rules and their security associations: + +**Netsh** + +``` syntax +netsh advfirewall monitor show mmsa all +``` + +Windows PowerShell + +``` syntax +Get-NetIPsecMainModeSA +``` + +### Find the source GPO of a rule + +To view the properties of a particular rule or group of rules, you query for the rule. When a query returns fields that are specified as **NotConfigured**, you can to determine which policy store a rule originates from. + +For objects that come from a GPO (the *–PolicyStoreSourceType* parameter is specified as **GroupPolicy** in the **Show** command), if *–TracePolicyStore* is passed, the name of the GPO is found and returned in the **PolicyStoreSource** field. + +Windows PowerShell + +``` syntax +Get-NetIPsecRule –DisplayName “Require Inbound Authentication” –TracePolicyStore +``` + +It is important to note that the revealed sources do not contain a domain name. + +### Deploy a basic domain isolation policy + +IPsec can be used to isolate domain members from non-domain members. Domain isolation uses IPsec authentication to require that the domain-joined devices positively establish the identities of the communicating devices to improve security of an organization. One or more features of IPsec can be used to secure traffic with an IPsec rule object. + +To implement domain isolation on your network, the devices in the domain receive IPsec rules that block unsolicited inbound network traffic that is not protected by IPsec. Here we create an IPsec rule that requires authentication by domain members. Through this, you can isolate domain-joined devices from devices that are not joined to a domain.

They require authentication when communicating among each other and reject non-authenticated inbound connections. To improve the security of servers with sensitive data, this data must be protected by allowing access only to a subset of devices within the enterprise domain. + +IPsec can provide this additional layer of protection by isolating the server. In server isolation, sensitive data access is restricted to users and devices with legitimate business need, and the data is additionally encrypted to prevent eavesdropping. + +### Create a firewall rule that requires group membership and encryption + +To deploy server isolation, we layer a firewall rule that restricts traffic to authorized users or devices on the IPsec rule that enforces authentication. + +The following firewall rule allows Telnet traffic from user accounts that are members of a custom group called “Authorized to Access Server.” This access can additionally be restricted based on the device, user, or both by specifying the restriction parameters. + +A Security Descriptor Definition Language (SDDL) string is created by extending a user or group’s security identifier (SID).

This application can send data, such as names and passwords, over the network. This data can be intercepted by malicious users. If an administrator would like to allow the use of Telnet, but protect the traffic, a firewall rule that requires IPsec encryption can be created. This is necessary so that the administrator can be certain that when this application is used, all of the traffic sent or received by this port is encrypted. If IPsec fails to authorize the connection, no traffic is allowed from this application. + +In this example, we allow only authenticated and encrypted inbound Telnet traffic from a specified secure user group through the creation of the following firewall rule. + +**Netsh** + +``` syntax +netsh advfirewall set store gpo=domain.contoso.com\Server_Isolation +netsh advfirewall firewall add rule name=“Allow Encrypted Inbound Telnet to Group Members Only” program=%SystemRoot%\System32\tlntsvr.exe protocol=TCP dir=in action=allow localport=23 security=authenc rmtusrgrp ="D:(A;;CC;;; S-1-5-21-2329867823-2610410949-1491576313-1735)" +``` + +Windows PowerShell + +``` syntax +New-NetFirewallRule -DisplayName "Allow Encrypted Inbound Telnet to Group Members Only" -Program %SystemRoot%\System32\tlntsvr.exe -Protocol TCP -Direction Inbound -Action Allow -LocalPort 23 -Authentication Required -Encryption Required –RemoteUser $secureUserGroup –PolicyStore domain.contoso.com\Server_Isolation +``` + +### Endpoint security enforcement + +The previous example showed end to end security for a particular application.

Windows Firewall with Advanced Security also supports Internet Protocol security (IPsec), which you can use to require authentication from any device that is attempting to communicate with your device. When authentication is required, devices that cannot be authenticated as a trusted device cannot communicate with your device. You can also use IPsec to require that certain network traffic is encrypted to prevent it from being read by network packet analyzers that could be attached to the network by a malicious user. + +The Windows Firewall with Advanced Security MMC snap-in is more flexible and provides much more functionality than the consumer-friendly Windows Firewall interface found in the Control Panel.

The guide describes some of the common goals for using Windows Firewall with Advanced Security, and then helps you map the goals that apply to your scenario to the designs that are presented in this guide. + +This guide is intended for the IT professional who has been assigned the task of deploying firewall and IPsec technologies on an organization's network to help meet the organization's security goals. + +Windows Firewall with Advanced Security should be part of a comprehensive security solution that implements a variety of security technologies, such as perimeter firewalls, intrusion detection systems, virtual private networking (VPN), IEEE 802.1X authentication for wireless and wired connections, and IPsec connection security rules. + +To successfully use this guide, you need a good understanding of both the capabilities provided by Windows Firewall with Advanced Security, and how to deliver configuration settings to your managed devices by using Group Policy in Active Directory. + +You can use the deployment goals to form one of these Windows Firewall with Advanced Security designs, or a custom design that combines elements from those presented here: + +- **Basic firewall policy design**. Restricts network traffic in and out of your devices to only that which is needed and authorized. + +- **Domain isolation policy design**. Prevents devices that are domain members from receiving unsolicited network traffic from devices that are not domain members. Additional "zones" can be established to support the special requirements of some devices, such as: + + - A "boundary zone" for devices that must be able to receive requests from non-isolated devices. + + - An "encryption zone" for devices that store sensitive data that must be protected during network transmission. + +- **Server isolation policy design**. Restricts access to a server to only a limited group of authorized users and devices. Commonly configured as a zone in a domain isolation design, but can also be configured as a stand-alone design, providing many of the benefits of domain isolation to a small set of devices. + +- **Certificate-based isolation policy design**. This design is a complement to either of the previous two designs, and supports any of their capabilities. It uses cryptographic certificates that are deployed to clients and servers for authentication, instead of the Kerberos V5 authentication used by default in Active Directory.

Devices in a domain share a common directory database and security policies. Multiple domains can co-exist in a "forest," with trust relationships that establish the forest as the security boundary. | +| Authentication | A process that enables the sender of a message to prove its identity to the receiver. For connection security in Windows, authentication is implemented by the IPsec protocol suite.| +| Boundary zone | A subset of the devices in an isolated domain that must be able to receive unsolicited and non-authenticated network traffic from devices that are not members of the isolated domain. Devices in the boundary zone request but do not require authentication. They use IPsec to communicate with other devices in the isolated domain.| +| Connection security rule | A rule in Windows Firewall with Advanced Security that contains a set of conditions and an action to be applied to network packets that match the conditions. The action can allow the packet, block the packet, or require the packet to be protected by IPsec. In previous versions of Windows, this was called an *IPsec rule*.| +| Certificate-based isolation | A way to add devices that cannot use Kerberos V5 authentication to an isolated domain, by using an alternate authentication technique. Every device in the isolated domain and the devices that cannot use Kerberos V5 are provided with a device certificate that can be used to authenticate with each other. Certificate-based isolation requires a way to create and distribute an appropriate certificate (if you choose not to purchase one from a commercial certificate provider).| +| Domain isolation | A technique for helping protect the devices in an organization by requiring that the devices authenticate each other's identity before exchanging information, and refusing connection requests from devices that cannot authenticate. Domain isolation takes advantage of Active Directory domain membership and the Kerberos V5 authentication protocol available to all members of the domain. Also see "Isolated domain" in this table.| +| Encryption zone | A subset of the devices in an isolated domain that process sensitive data. Devices that are part of the encryption zone have all network traffic encrypted to prevent viewing by non-authorized users. Devices that are part of the encryption zone also typically are subject to the access control restrictions of server isolation.| +| Firewall rule | A rule in Windows Firewall with Advanced Security that contains a set of conditions used to determine whether a network packet is allowed to pass through the firewall.
By default, the firewall rules in Windows Server 2012, Windows Server 2008 R2, Windows Server 2008, Windows 8, Windows 7, and Windows Vista block unsolicited inbound network traffic. Likewise, by default, all outbound network traffic is allowed. The firewall included in previous versions of Windows only filtered inbound network traffic. | +| Internet Protocol security (IPsec) | A set of industry-standard, cryptography-based protection services and protocols. IPsec protects all protocols in the TCP/IP protocol suite except Address Resolution Protocol (ARP).| +| IPsec policy | A collection of connection security rules that provide the required protection to network traffic entering and leaving the device. The protection includes authentication of both the sending and receiving device, integrity protection of the network traffic exchanged between them, and can include encryption.| +| Isolated domain | An Active Directory domain (or an Active Directory forest, or set of domains with two-way trust relationships) that has Group Policy settings applied to help protect its member devices by using IPsec connection security rules. Members of the isolated domain require authentication on all unsolicited inbound connections (with exceptions handled by the other zones).
In this guide, the term *isolated domain* refers to the IPsec concept of a group of devices that can share authentication. The term *Active Directory domain* refers to the group of devices that share a security database by using Active Directory.| +| Server isolation | A technique for using group membership to restrict access to a server that is typically already a member of an isolated domain. The additional protection comes from using the authentication credentials of the requesting device to determine its group membership, and then only allowing access if the computer account (and optionally the user account) is a member of an authorized group.| +| Solicited network traffic | Network traffic that is sent in response to a request. By default, Windows Firewall with Advanced Security allows all solicited network traffic through.| +| Unsolicited network traffic | Network traffic that is not a response to an earlier request, and that the receiving device cannot necessarily anticipate. By default, Windows Firewall with Advanced Security blocks all unsolicited network traffic. | +| Zone | A zone is a logical grouping of devices that share common IPsec policies because of their communications requirements. For example, the boundary zone permits inbound connections from non-trusted devices. The encryption zone requires that all connections be encrypted.
This is not related to the term zone as used by Domain Name System (DNS). | + +**Next:** [Understanding the Windows Firewall with Advanced Security Design Process](understanding-the-windows-firewall-with-advanced-security-design-process.md) + +  + +  + + + + + diff --git a/windows/keep-secure/windows-firewall-with-advanced-security.md b/windows/keep-secure/windows-firewall-with-advanced-security.md new file mode 100644 index 0000000000..51c6967315 --- /dev/null +++ b/windows/keep-secure/windows-firewall-with-advanced-security.md @@ -0,0 +1,42 @@ +--- +title: Windows Firewall with Advanced Security (Windows 10) +description: Windows Firewall with Advanced Security +ms.prod: w10 +ms.mktglfcycl: deploy +ms.sitesec: library +ms.pagetype: security +author: brianlic-msft +--- + +# Windows Firewall with Advanced Security + +**Applies to** +- Windows 10 +- Windows Server 2016 Technical Preview + +This is an overview of the Windows Firewall with Advanced Security (WFAS) and Internet Protocol security (IPsec) features. + +## Feature description + +Windows Firewall with Advanced Security is an important part of a layered security model. By providing host-based, two-way network traffic filtering for a device, Windows Firewall with Advanced Security blocks unauthorized network traffic flowing into or out of the local device. Windows Firewall with Advanced Security also works with Network Awareness so that it can apply security settings appropriate to the types of networks to which the device is connected. Windows Firewall and Internet Protocol Security (IPsec) configuration settings are integrated into a single Microsoft Management Console (MMC) named Windows Firewall with Advanced Security, so Windows Firewall is also an important part of your network’s isolation strategy. + +## Practical applications + + +To help address your organizational network security challenges, Windows Firewall with Advanced Security offers the following benefits: + +- **Reduces the risk of network security threats.**  Windows Firewall with Advanced Security reduces the attack surface of a device, providing an additional layer to the defense-in-depth model. Reducing the attack surface of a device increases manageability and decreases the likelihood of a successful attack. + +- **Safeguards sensitive data and intellectual property.**  With its integration with IPsec, Windows Firewall with Advanced Security provides a simple way to enforce authenticated, end-to-end network communications. It provides scalable, tiered access to trusted network resources, helping to enforce integrity of the data, and optionally helping to protect the confidentiality of the data. + +- **Extends the value of existing investments.**  Because Windows Firewall with Advanced Security is a host-based firewall that is included with the operating system, there is no additional hardware or software required. Windows Firewall with Advanced Security is also designed to complement existing non-Microsoft network security solutions through a documented application programming interface (API). + +## In this section + +| Topic | Description +| - | - | +| [Isolating Windows Store Apps on Your Network](isolating-apps-on-your-network.md) | You can customize your Windows Firewall configuration to isolate the network access of Windows Store apps that run on devices. | +| [Securing End-to-End IPsec Connections by Using IKEv2 in Windows Server 2012](securing-end-to-end-ipsec-connections-by-using-ikev2.md) | You can use IKEv2 to help secure your end-to-end IPSec connections. | +| [Windows Firewall with Advanced Security Administration with Windows PowerShell](windows-firewall-with-advanced-security-administration-with-windows-powershell.md) | Learn more about using Windows PowerShell to manage the Windows Firewall. | +| [Windows Firewall with Advanced Security Design Guide](windows-firewall-with-advanced-security-design-guide.md) | Learn how to create a design for deploying Windows Firewall with Advanced Security. | +| [Windows Firewall with Advanced Security Deployment Guide](windows-firewall-with-advanced-security-deployment-guide.md) | Learn how to deploy Windows Firewall with Advanced Security. | diff --git a/windows/manage/acquire-apps-windows-store-for-business.md b/windows/manage/acquire-apps-windows-store-for-business.md index 8e22322f1c..5f68e8e296 100644 --- a/windows/manage/acquire-apps-windows-store-for-business.md +++ b/windows/manage/acquire-apps-windows-store-for-business.md @@ -1,9 +1,11 @@ --- title: Acquire apps in Windows Store for Business (Windows 10) description: As an admin, you can acquire apps from the Windows Store for Business for your employees.
