 >[!NOTE]
 >When Windows 10 first shipped, it included Microsoft Passport and Windows Hello, which worked together to provide multi-factor authentication. To simplify deployment and improve supportability, Microsoft has combined these technologies into a single solution under the Windows Hello name. Customers who have already deployed these technologies will not experience any change in functionality. Customers who have yet to evaluate Windows Hello will find it easier to deploy due to simplified policies, documentation, and semantics.

+Because we realize your employees are going to want to use this new technology in your enterprise, we've been actively working with the device manufacturers to create strict design and performance recommendations that help to ensure that you can more confidently introduce Windows Hello biometrics into your organization.
 
 ## How does Windows Hello work?
 Windows Hello lets your employees use fingerprint or facial recognition as an alternative method to unlocking a device. With Windows Hello, authentication happens when the employee provides his or her unique biometric identifier while accessing the device-specific Windows Hello credentials.
 
-The Windows Hello authenticator works to authenticate and allow employees onto your enterprise network. Authentication doesn’t roam among devices, isn’t shared with a server, and can’t easily be extracted from a device. If multiple employees share a device, each employee will use his or her own biometric data on the device.

Authentication doesn't roam among devices, isn't shared with a server, and can't easily be extracted from a device. If multiple employees share a device, each employee will use his or her own biometric data on the device.
 
 ## Why should I let my employees use Windows Hello?
 Windows Hello provides many benefits, including:
 
--   It helps to strengthen your protections against credential theft. Because an attacker must have both the device and the biometric info or PIN, it’s much more difficult to gain access without the employee’s knowledge.

+-   Employees get a simple authentication method (backed up with a PIN) that's always with them, so there's nothing to lose. No more forgetting passwords!
 
 -   Support for Windows Hello is built into the operating system so you can add additional biometric devices and polices as part of a coordinated rollout or to individual employees or groups using Group Policy or Mobile Device Management (MDM) configurations service provider (CSP) policies.<br>For more info about the available Group Policies and MDM CSPs, see the [Implement Windows Hello for Business in your organization](hello-manage-in-organization.md) topic.
 
 ## Where is Windows Hello data stored?
-The biometric data used to support Windows Hello is stored on the local device only. It doesn’t roam and is never sent to external devices or servers. This separation helps to stop potential attackers by providing no single collection point that an attacker could potentially compromise to steal biometric data. Additionally, even if an attacker was actually able to get the biometric data, it still can’t be easily converted to a form that could be recognized by the biometric sensor.
+The biometric data used to support Windows Hello is stored on the local device only. It doesn't roam and is never sent to external devices or servers. This separation helps to stop potential attackers by providing no single collection point that an attacker could potentially compromise to steal biometric data. Additionally, even if an attacker was actually able to get the biometric data from a device, it cannot be converted back into a raw biometric sample that could be recognized by the biometric sensor.
+
+Each sensor on a device will have its own biometric database file where template data is stored. Each database has a unique, randomly generated key that is encrypted to the system. The template data for the sensor will be encrypted with this per-database key using AES with CBC chaining mode. The hash is SHA256. Some fingerprint sensors have the capability to complete matching on the fingerprint sensor module instead of in the OS. These sensors will store biometric data on the fingerprint module instead of in the database file.

+We've been working with the device manufacturers to help ensure a high-level of performance and protection is met by each sensor and device, based on these requirements:
 
 -   **False Accept Rate (FAR).** Represents the instance a biometric identification solution verifies an unauthorized person. This is normally represented as a ratio of number of instances in a given population size, for example 1 in 100 000. This can also be represented as a percentage of occurrence, for example, 0.001%. This measurement is heavily considered the most important with regards to the security of the biometric algorithm.
 
 -   **False Reject Rate (FRR).** Represents the instances a biometric identification solution fails to verify an authorized person correctly. Usually represented as a percentage, the sum of the True Accept Rate and False Reject Rate is 1. Can be with or without anti-spoofing or liveness detection.
 
 ### Fingerprint sensor requirements
-To allow fingerprint matching, you must have devices with fingerprint sensors and software. Fingerprint sensors, or sensors that use an employee’s unique fingerprint as an alternative log on option, can be touch sensors (large area or small area) or swipe sensors. Each type of sensor has its own set of detailed requirements that must be implemented by the manufacturer, but all of the sensors must include anti-spoofing measures (required).

On devices that support Windows Hello, an easy biometric gesture unlocks users' credentials.
  
 - **Facial recognition**. This type of biometric recognition uses special cameras that see in IR light, which allows them to reliably tell the difference between a photograph or scan and a living person. Several vendors are shipping external cameras that incorporate this technology, and major laptop manufacturers are incorporating it into their devices, as well. 
 - **Fingerprint recognition**. This type of biometric recognition uses a capacitive fingerprint sensor to scan your fingerprint. Fingerprint readers have been available for Windows computers for years, but the current generation of sensors is significantly more reliable and less error-prone. Most existing fingerprint readers (whether external or integrated into laptops or USB keyboards) work with Windows 10. 
 
-Windows stores biometric data that is used to implement Windows Hello securely on the local device only. The biometric data doesn’t roam and is never sent to external devices or servers. Because Windows Hello only stores biometric identification data on the device, there’s no single collection point an attacker can compromise to steal biometric data. 
-
-## From Windows 10 version 1803, the Windows Hello feature can be used as a safe and secure sign-in method.
-Fingerprint scan can be enabled on laptop computers using a built-in fingerprint reader or an external USB fingerprint reader, as follows:
-1. Go to **Settings** > **Accounts** > **Sign-in-options** > **Windows Hello Fingerprint** > **Add fingerprint**
-2. Users will need to add a PIN after adding their fingerprint(s) to the reader configuration.
-3. Windows Biometric data is located in the `C:\Windows\System32\WinBioDatabase\` folder (fingerprint data is stored with the .DAT file name extension).
-4. If you are unable to sign in with previously registered fingerprints, delete the entire content of this folder and register your fingerprints again.

-There are many options from which you can choose when deploying Windows Hello for Business. Providing multiple options ensures nearly every organization can deploy Windows Hello for Business. Providing many options makes the deployment appear complex, however, most organization will realize they’ve already implemented most of the infrastructure on which the Windows Hello for Business deployment depends. It is important to understand that Windows Hello for Business is a distributed system and does take proper planning across multiple teams within an organization.

+A deployment's trust type defines how each Windows Hello for Business client authenticates to the on-premises Active Directory.  There are two trust types: key trust and certificate trust.
 
-The key trust type does not require issuing authentication certificates to end users. Users authenticate using a hardware-bound key created during the built-in provisioning experience. This requires an adequate distribution of Windows Server 2016 domain controllers relative to your existing authentication and the number of users included in your Windows Hello for Business deployment. Read the [Planning an adequate number of Windows Server 2016 Domain Controllers for Windows Hello for Business deployments](hello-adequate-domain-controllers.md) to learn more.

-The built-in Windows Hello for Business provisioning experience creates a hardware bound asymmetric key pair as their user’s credentials. The private key is protected by the device’s security modules; however, the credential is a user key (not a device key).  The provisioning experience registers the user’s public key with the identity provider.  For cloud only and hybrid deployments, the identity provider is Azure Active Directory.  For on-premises deployments, the identity provider is the on-premises server running Windows Server 2016 Active Directory Federation Services (AD FS) role.

 #### Multifactor authentication
 
 > [!IMPORTANT]
 > As of July 1, 2019, Microsoft will no longer offer MFA Server for new deployments. New customers who require multi-factor authentication for their users should use cloud-based Azure Multi-Factor Authentication. Existing customers who have activated MFA Server prior to July 1, 2019 will be able to download the latest version, future updates and generate activation credentials as usual. See [Getting started with the Azure Multi-Factor Authentication Server](https://docs.microsoft.com/azure/active-directory/authentication/howto-mfaserver-deploy) for more details.
 
-The goal of Windows Hello for Business is to move organizations away from passwords by providing them a strong credential that provides easy two-factor authentication.  The built-in provisioning experience accepts the user’s weak credentials (username and password) as the first factor authentication; however, the user must provide a second factor of authentication before Windows provisions a strong credential.

 Cloud only and hybrid deployments provide many choices for multi-factor authentication.  On-premises deployments must use a multi-factor authentication that provides an AD FS multi-factor adapter to be used in conjunction with the on-premises Windows Server 2016 AD FS server role. Organizations can use the on-premises Azure Multi-factor Authentication server, or choose from several third parties (Read [Microsoft and third-party additional authentication methods](https://docs.microsoft.com/windows-server/identity/ad-fs/operations/configure-additional-authentication-methods-for-ad-fs#microsoft-and-third-party-additional-authentication-methods) for more information).

-Unfortunately, no organization has unlimited resources to monitor every resource and activity on a network. If you do not plan well, you will likely have gaps in your auditing strategy.

This could cause delays or even prevent auditors from identifying suspicious activity. Thus, too much monitoring can leave an organization as vulnerable as not enough monitoring.

+A security audit policy must support and be an integrated aspect of an organization's overall security framework.
 
-Every organization has a unique set of data and network assets (such as customer and financial data and trade secrets), physical resources (such as desktop computers, portable computers, and servers), and users (which can include various internal groups such as finance and marketing, and external groups such as partners, customers, and anonymous users on the website). Not all of these assets, resources, and users justify the cost of an audit. Your task is to identify which assets, resources, and users provide the strongest justification for the focus of a security audit.

 To create your Windows security audit plan, begin by identifying:
 
--   The overall network environment, including the domains, OUs, and security groups.
--   The resources on the network, the users of those resources, and how those resources are being used.
--   Regulatory requirements.

 ### Network environment
 
-An organization's domain and OU structure provide a fundamental starting point for thinking about how to apply a security audit policy because it likely provides a foundation of Group Policy Objects (GPOs) and logical grouping of resources and activities that you can use to apply the audit settings that you choose. It is also likely that certain portions of your domain and OU structure already provide logical groups of users, resources, and activities that justify the time and resources needed to audit them. For information about how to integrate a security audit policy with your domain and OU structure, see [Mapping security audit policy to groups of users, computers, and resources in your organization](#bkmk-2) later in this document.

-In addition to your domain model, you should also find out whether your organization creates and maintains a systematic threat model. A good threat model can help you identify threats to key components in your infrastructure, so you can define and apply audit settings that enhance the organization's ability to identify and counter those threats.

 ### Data and resources
 
-For data and resource auditing, you need to identify the most important types of data and resources (such as patient records, accounting data, or marketing plans) that can benefit from the closer monitoring that Windows auditing can provide. Some of these data resources might already be monitored through auditing features in products such as Microsoft SQL Server and Exchange Server. If so, you may want to consider how Windows auditing features can enhance the existing audit strategy. As with the domain and OU structure discussed previously, security auditing should focus on your most critical resources. You also must consider how much audit data you will be able to manage.

-You can record if these resources have high business impact, medium business impact, or low business impact, the cost to the organization if these data resources are accessed by unauthorized users, and the risk that this access can pose to the organization. The type of access by users (such as Read, Modify, or Copy) can also pose different levels of risk to an organization.

The type of access by users (such as *read*, *modify*, or *copy*) can also pose different levels of risk.
 
-Increasingly, data access and use is governed by regulations, and a breach can result in severe penalties and a loss in credibility for the organization. If regulatory compliance plays a role in how you manage your data, be sure to also document this information.

 ### Users
 
-Many organizations find it useful to classify the types of users they have and base permissions on this classification. This same classification can help you identify which user activities should be the subject of security auditing and the amount of audit data they will generate.
+Many organizations find it useful to classify the types of users they have and then base permissions on this classification. This classification can help you identify which user activities should be the subject of security auditing and the amount of audit data that they'll generate.
 
-Organizations can create distinctions based on the type of rights and permissions needed by users to perform their jobs. For example, under the classification Administrators, larger organizations might assign local administrator responsibilities for a single computer, for specific applications such as Exchange Server or SQL Server, or for an entire domain. Under Users, permissions and Group Policy settings can apply to as many as all users in an organization or as few as a subset of the employees in a given department.

 ### Computers
 
 Security and auditing requirements and audit event volume can vary considerably for different types of computers in an organization. These requirements can be based on:

 ### Regulatory requirements
 
-Many industries and locales have strict and specific requirements for network operations and how resources are protected. In the health care and financial industries, for example, there are strict guidelines for who has access to records and how they are used. Many countries have strict privacy rules. To identify regulatory requirements, work with your organization's legal department and other departments responsible for these requirements. Then consider the security configuration and auditing options that can be used to comply with and verify compliance with these regulations.

+By using Group Policy, you can apply your security audit policy to defined groups of users, computers, and resources. To map a security auditing policy to these defined groups in your organization, you should understand the following considerations for using Group Policy to apply security audit policy settings:
 
 -   The policy settings you identify can be applied by using one or more GPOs. To create and edit a GPO, use the Group Policy Management Console (GPMC). By using the GPMC to link a GPO to selected Active Directory sites, domains, and OUs, you apply the policy settings in the GPO to the users and computers in those Active Directory objects. An OU is the lowest-level Active Directory container to which you can assign Group Policy settings.
--   For every policy setting that you select, you need to decide whether it should be enforced across the organization, or whether it should apply only to selected users or computers. You can then combine these audit policy settings into GPOs and link them to the appropriate Active Directory containers.
--   By default, options set in GPOs that are linked to higher levels of Active Directory sites, domains, and OUs are inherited by all OUs at lower levels. However, a GPO that is linked at a lower level can overwrite inherited policies.

+-   By default, options set in GPOs that are linked to higher levels of Active Directory sites, domains, and OUs are inherited by all OUs at lower levels. However, a GPO that's linked at a lower level can overwrite inherited policies.
 
-    For example, you might use a domain GPO to assign an organization-wide group of audit settings, but want a certain OU to get a defined group of additional settings. To accomplish this, you can link a second GPO to that specific lower-level OU. Therefore, a logon audit setting that is applied at the OU level will override a conflicting logon audit setting that is applied at the domain level (unless you have taken special steps to apply Group Policy loopback processing).

Then, a logon audit setting that's applied at the OU level will override a conflicting logon audit setting that's applied at the domain level, unless you've taken special steps to apply Group Policy loopback processing.
 
--   Audit policies are computer policies. Therefore, they must be applied through GPOs that are applied to computer OUs, not to user OUs. However, in most cases you can apply audit settings for only specified resources and groups of users by configuring SACLs on the relevant objects. This enables auditing for a security group that contains only the users you specify.

But in most cases, you can apply audit settings for only specified resources and groups of users by configuring SACLs on the relevant objects. This functionality enables auditing for a security group that contains only the users you specify.
 
-    For example, you could configure a SACL for a folder called Payroll Data on Accounting Server 1. This can audit attempts by members of the Payroll Processors OU to delete objects from this folder. The **Object Access\\Audit File System** audit policy setting applies to Accounting Server 1, but because it requires a corresponding resource SACL, only actions by members of the Payroll Processors OU on the Payroll Data folder generates audit events.

+-   Advanced security audit policy settings were introduced in Windows Server 2008 R2 and Windows 7. These advanced audit policies can only be applied to those operating systems and later versions by using Group Policy.
 
-    >**Important:**  Whether you apply advanced audit policies by using Group Policy or by using logon scripts, do not use both the basic audit policy settings under **Local Policies\\Audit Policy** and the advanced settings under **Security Settings\\Advanced Audit Policy Configuration**. Using both basic and advanced audit policy settings can cause unexpected results in audit reporting.
 
-    If you use **Advanced Audit Policy Configuration** settings or use logon scripts to apply advanced audit policies, be sure to enable the **Audit: Force audit policy subcategory settings (Windows Vista or later) to override audit policy category settings** policy setting under **Local Policies\\Security Options**. This will prevent conflicts between similar settings by forcing basic security auditing to be ignored.

+The following examples show how you can apply audit policies to an organization's OU structure:
 
--   Apply data activity settings to an OU that contains file servers. If your organization has servers that contain particularly sensitive data, consider putting them in a separate OU so that you can configure and apply a more precise audit policy to these servers.
--   Apply user activity audit policies to an OU that contains all computers in the organization. If your organization places users in OUs based on the department they work in, consider configuring and applying more detailed security permissions on critical resources that are accessed by employees who work in more sensitive areas, such as network administrators or the legal department.

+Compromise to an organization's data resources can cause tremendous financial losses, lost prestige, and legal liability. If your organization has critical data resources that must be protected, the following settings can provide valuable monitoring and forensic data:
 
--   Object Access\\[Audit File Share](audit-file-share.md). This policy setting allows you to track what content was accessed, the source (IP address and port) of the request, and the user account that was used for the access. The volume of event data generated by this setting will vary depending on the number of client computers that attempt to access the file share. On a file server or domain controller, volume may be high due to SYSVOL access by client computers for policy processing. If you do not need to record routine access by client computers that have permissions on the file share, you may want to log audit events only for failed attempts to access the file share.
--   Object Access\\[Audit File System](audit-file-system.md). This policy setting determines whether the operating system audits user attempts to access file system objects. Audit events are only generated for objects (such as files and folders) that have configured SACLs, and only if the type of access requested (such as Write, Read, or Modify) and the account that is making the request match the settings in the SACL.
+-   **Object Access\\[Audit File Share](audit-file-share.md)**: This policy setting enables you to track what content was accessed, the source (IP address and port) of the request, and the user account that was used for the access. The volume of event data generated with this setting will vary depending on the number of client computers that try to access the file share. On a file server or domain controller, volume may be high because of SYSVOL access by client computers for policy processing.

-    If success auditing is enabled, an audit entry is generated each time any account successfully accesses a file system object that has a matching SACL. If failure auditing is enabled, an audit entry is generated each time any user unsuccessfully attempts to access a file system object that has a matching SACL. The amount of audit data generated by the **Audit File System** policy setting can vary considerably, depending on the number of objects that have been configured to be monitored.

-In the majority of cases, these attempts will be legitimate and a network needs to make vital data readily available to legitimate users. However in other cases, employees, partners, and others may attempt to access resources that they have no legitimate reason to access. Security auditing can be used to track a wide variety of user activities on a particular computer to diagnose and resolve problems for legitimate users and identify and address illegitimate activities. The following are a few important settings that you should evaluate to track user activity on your network:

But in other cases, employees, partners, and others may try to access resources that they have no legitimate reason to access. You can use security auditing to track a variety of user activities on a particular computer to diagnose and resolve problems for legitimate users and to identify and address illegitimate activities. The following are important settings that you should evaluate to track user activity on your network:
 
--   Account Logon\\[Audit Credential Validation](audit-credential-validation.md). This is an extremely important policy setting because it enables you to track every successful and unsuccessful attempt to present credentials for a user logon. In particular, a pattern of unsuccessful attempts may indicate that a user or application is using credentials that are no longer valid, or attempting to use a variety of credentials in succession in hope that one of these attempts will eventually be successful. These events occur on the computer that is authoritative for the credentials. For domain accounts, the domain controller is authoritative. For local accounts, the local computer is authoritative.
--   Detailed Tracking\\[Audit Process Creation](audit-process-creation.md) and Detailed Tracking\\[Audit Process Termination](audit-process-termination.md). These policy settings can enable you to monitor the applications that a user opens and closes on a computer.
--   DS Access\\[Audit Directory Service Access](audit-directory-service-access.md) and DS Access\\[Audit Directory Service Changes](audit-directory-service-changes.md). These policy settings provide a detailed audit trail of attempts to access create, modify, delete, move, or undelete objects in Active Directory Domain Services (AD DS). Only domain administrators have permissions to modify AD DS objects, so it is extremely important to identify malicious attempts to modify these objects. In addition, although domain administrators should be among an organization's most trusted employees, the use of **Audit Directory Service Access** and **Audit Directory Service Changes** settings allow you to monitor and verify that only approved changes are made to AD DS. These audit events are logged only on domain controllers.
--   Logon/Logoff\\[Audit Account Lockout](audit-account-lockout.md). Another common security scenario occurs when a user attempts to log on with an account that has been locked out. It is important to identify these events and to determine whether the attempt to use an account that has been locked out is malicious.
--   Logon/Logoff\\[Audit Logoff](audit-logoff.md) and Logon/Logoff\\[Audit Logon](audit-logon.md). Logon and logoff events are essential to tracking user activity and detecting potential attacks. Logon events are related to the creation of logon sessions, and they occur on the computer that was accessed. For an interactive logon, events are generated on the computer that was logged on to. For network logon, such as accessing a shared resource, events are generated on the computer that hosts the resource that was accessed. Logoff events are generated when logon sessions are terminated.
+-   **Account Logon\\[Audit Credential Validation](audit-credential-validation.md)**: This setting enables you to track all successful and unsuccessful logon attempts. A pattern of unsuccessful attempts may indicate that a user or application is using credentials that are no longer valid. Or the user or app is trying to use a variety of credentials in succession in hope that one of these attempts will eventually succeed. These events occur on the computer that's authoritative for the credentials. For domain accounts, the domain controller is authoritative. For local accounts, the local computer is authoritative.
+-   **Detailed Tracking\\[Audit Process Creation](audit-process-creation.md) and Detailed Tracking\\[Audit Process Termination](audit-process-termination.md)**: These policy settings enable you to monitor the applications that a user opens and close on a computer.

Logoff events are generated when logon sessions are terminated.
 
-    >**Note:**  There is no failure event for logoff activity because failed logoffs (such as when a system abruptly shuts down) do not generate an audit record. Logoff events are not 100 percent reliable. For example, the computer can be turned off without a proper logoff and shutdown, and a logoff event is not generated.

The Security Accounts Manager (SAM) is a database that is present on computers running Windows that stores user accounts and security descriptors for users on the local computer. Changes to user and group objects are tracked by the **Account Management** audit category. However, user accounts with the proper user rights could potentially alter the files where the account and password information is stored in the system, bypassing any **Account Management** events.
--   Privilege Use\\[Audit Sensitive Privilege Use](audit-sensitive-privilege-use.md). **Privilege Use** policy settings and audit events allow you to track the use of certain rights on one or more systems. If you configure this policy setting, an audit event is generated when sensitive rights requests are made.

Many networks support large numbers of external users, including remote employees and partners. Because these users are outside the organization's network boundaries, IPsec is often used to help protect communications over the Internet by enabling network-level peer authentication, data origin authentication, data integrity, data confidentiality (encryption), and protection against replay attacks. You can use these settings to ensure that IPsec services are functioning properly.

-Networks can contain hundreds of servers running critical services or storing critical data, all of which need to be monitored. The number of client computers on the network can easily range into the tens or even hundreds of thousands. This may not be an issue if the ratio of servers or client computers per administrator is low. Even if an administrator who is responsible for auditing security and performance issues has relatively few computers to monitor, you need to decide how an administrator will obtain event data to review.

And even if an administrator who is responsible for auditing security and performance issues has relatively few computers to monitor, you need to decide how the administrator will obtain event data to review. Following are some options for obtaining the event data.
 
--   Will you keep event data on a local computer until an administrator logs on to review this data? If so, then the administrator needs to have physical or remote access to the Event Viewer on each client computer or server, and the remote access and firewall settings on each client computer or server need to be configured to enable this access. In addition, you need to decide how often an administrator can visit each computer, and adjust the size of the audit log so that critical information is not deleted if the log reaches its maximum capacity.
--   Will you collect event data so that it can be reviewed from a central console? If so, there are a number of computer management products, such as the Audit Collection Services in Operations Manager 2007 and 2012, which can be used to collect and filter event data. Presumably this solution enables a single administrator to review larger amounts of data than using the local storage option. But in some cases, this can make it more difficult to detect clusters of related events that can occur on a single computer.

+## Unknown – Unrecognized software  
+
+No antivirus or protection technology is perfect. It takes time to identify and block malicious sites and applications, or trust newly released programs and certificates.  With almost 2 billion websites on the internet and software continuously being updated and released, it's impossible to have information about every single site and program.
+
+You can think of Unknown/Uncommonly downloaded warnings as an early warning system for potentially undetected malware, as there is generally a delay from the time new malware is released until it is identified. Not all uncommon programs are malicious, but the risk in the unknown category is significantly higher for the typical user. Warnings for unknown software are not blocks, and users can choose to download and run the application normally if they wish to.
+
+Once enough data is gathered, Microsoft's security solutions can make a determination. Either no threats are found, or an application or software is categorized as malware or potentially unwanted software.

 ## To what extent are tests representative of protection in the real world?
 
-Independent security industry tests aim to evaluate the best antivirus and security products in an unbiased manner. However, it is important to remember that Microsoft sees a wider and broader set of threats beyond what’s tested in the evaluations highlighted in this topic. For example, in an average month Microsoft's security products identify over 100 million new threats. Even if an independent tester can acquire and test 1% of those threats, that is a million tests across 20 or 30 products. In other words, the vastness of the malware landscape makes it extremely difficult to evaluate the quality of protection against real world threats.

 The capabilities within Microsoft Defender ATP provide [additional layers of protection](https://cloudblogs.microsoft.com/microsoftsecure/2017/12/11/detonating-a-bad-rabbit-windows-defender-antivirus-and-layered-machine-learning-defenses) that are not factored into industry antivirus tests, and address some of the latest and most sophisticated threats. Isolating AV from the rest of Microsoft Defender ATP creates a partial picture of how Microsoft's security stack operates in the real world. For example, attack surface reduction and endpoint detection & response capabilities can help prevent malware from getting onto devices in the first place. We have proven that [Microsoft Defender ATP components catch samples](https://query.prod.cms.rt.microsoft.com/cms/api/am/binary/RE2ouJA) that Windows Defender Antivirus missed in these industry tests, which is more representative of how effectively Microsoft's security suite protects customers in the real world.

+> [!NOTE]
+> In alignment with macOS evolution, we are preparing a Microsoft Defender ATP for Mac update that leverages system extensions instead of kernel extensions.
+> 
+> In the meantime, starting with macOS Catalina update 10.15.4, Apple introduced a user facing *Legacy System Extension* warning to signal applications that rely on kernel extensions.
+> 
+> If you have previously whitelisted the kernel extension as part of your remote deployment, that warning should not be presented to the end user. If you have not previously deployed a policy to whitelist the kernel extension, your users will be presented with the warning. To proactively silence the warning, you can still deploy a configuration to whitelist the kernel extension. Refer to the instructions in the [JAMF-based deployment](mac-install-with-jamf.md#approved-kernel-extension) and [Microsoft Intune-based deployment](mac-install-with-intune.md#create-system-configuration-profiles) topics.

 ## Reference
 
-The **Interactive logon: Prompt user to change password before expiration** policy setting determines how many days in advance users are warned that their passwords are about to expire. With this advance warning, the user has time to construct a password that is sufficiently strong.
+This policy setting determines when users are warned that their passwords are about to expire. This warning gives users time to select a strong password before their current password expires to avoid losing system access.
 
 ### Possible values
 
--   A user-defined number of days from 0 through 999.
--   Not defined.
+-   A user-defined number of days from 0 through 999
+-   Not defined
 
 ### Best practices
 
-1.  Configure user passwords to expire periodically. Users will need warning that their passwords are going to expire, or they might inadvertently get locked out of the system. This could lead to confusion for users who access the network locally, or make it impossible for users who access the network through dial-up or virtual private network (VPN) connections to log on.
-2.  Set **Interactive logon: Prompt user to change password before expiration** to 5 days. When their password expiration date is 5 or fewer days away, users will see a dialog box each time they log on to the domain.
-3.  Do not set the value to 0, which results in displaying the password expiration warning every time the user logs on.

 ### Vulnerability
 
-Session hijacking uses tools that allow attackers who have access to the same network as the client device or server to interrupt, end, or steal a session in progress. Attackers can potentially intercept and modify unsigned SMB packets and then modify the traffic and forward it so that the server might perform objectionable actions. Alternatively, the attacker could pose as the server or client computer after legitimate authentication, and gain unauthorized access to data.

Alternatively, the attacker could pose as the server or client computer after legitimate authentication and gain unauthorized access to data.
 
-SMB is the resource-sharing protocol that is supported by many Windows operating systems. It is the basis of many modern features like Storage Spaces Direct, Storage Replica, and SMB Direct, as well as many legacy protocols and tools. SMB signatures authenticate users and the servers that host the data. If either side fails the authentication process, data transmission does not take place.

 ### Countermeasure
 
 Enable **Microsoft network client: Digitally sign communications (always)**.
 
->[!NOTE]
->An alternative countermeasure that could protect all network traffic is to implement digital signatures with IPsec. There are hardware-based accelerators for IPsec encryption and signing that could be used to minimize the performance impact on the servers' CPUs. No such accelerators are available for SMB signing.

 ### Potential impact
 
-Storage speeds impact performance. A faster drive on the source and destination allows more throughput, which causes more CPU usage of signing. If you are using a 1 Gb Ethernet network or slower storage speed with a modern CPU, there is limited degradation in performance. If you are using a faster network (such as 10 Gb), the performance impact of signing may be greater.

-Enabling this policy setting allows a user’s account on one computer to be associated with an online identity, such as Microsoft Account, so that account can log on to a peer device (if the peer device is likewise configured) without the use of a Windows logon account (domain or local). Although this is beneficial for workgroups or home groups, using this feature in a domain-joined environment might circumvent your established security policies.

+Set this policy to *Disabled* or don't configure this security policy for domain-joined devices.
 
 ### Potential impact
 
-If you do not set or disable this policy, the PKU2U protocol will not be used to authenticate between peer devices, which forces users to follow domain defined access control policies. If you enable this policy, you will allow your users to authenticate by using local certificates between systems that are not part of a domain that uses PKU2U. This will allow users to share resources between devices

 ## Opt out of automatic exclusions
 
-In Windows Server 2016, the predefined exclusions delivered by Security intelligence updates only exclude the default paths for a role or feature. If you installed a role or feature in a custom path, or you want to manually control the set of exclusions, you need to opt out of the automatic exclusions delivered in Security intelligence updates.

If you installed a role or feature in a custom path, or you want to manually control the set of exclusions, make sure to opt out of the automatic exclusions delivered in Security intelligence updates. But keep in mind that the exclusions that are delivered automatically are optimized for Windows Server 2016 and 2019 roles. 
 
 > [!WARNING]
-> Opting out of automatic exclusions may adversely impact performance, or result in data corruption. The exclusions that are delivered automatically are optimized for Windows Server 2016 roles.

-> This setting is only supported on Windows Server 2016. While this setting exists in Windows 10, it doesn't have an effect on exclusions.

-> Since the predefined exclusions only exclude **default paths**, if you move NTDS and SYSVOL to another drive or path *different than the original one*, you would have to manually add the exclusions using the information [here](configure-extension-file-exclusions-windows-defender-antivirus.md#configure-the-list-of-exclusions-based-on-folder-name-or-file-extension) .

+# Better together: Windows Defender Antivirus and Office 365
+
+**Applies to:**
+
+- Windows Defender Antivirus
+- Office 365
+
+You might already know that:
+
+- **Windows Defender Antivirus protects your Windows 10 device from software threats, such as viruses, malware, and spyware**. Windows Defender Antivirus is your complete, ongoing protection, built into Windows 10 and ready to go. [Windows Defender Antivirus is your next-generation protection](https://docs.microsoft.com/windows/security/threat-protection/windows-defender-antivirus/windows-defender-antivirus-in-windows-10). 
+
+- **Office 365 includes antiphishing, antispam, and antimalware protection**. With your Office 365 subscription, you get premium email and calendars, Office apps, 1 TB of cloud storage (via OneDrive), and advanced security across all your devices. This is true for home and business users. And if you're a business user, and your organization is using Office 365 E5, you get even more protection through Office 365 Advanced Threat Protection. [Protect against threats with Office 365](https://docs.microsoft.com/microsoft-365/security/office-365-security/protect-against-threats).
+
+- **OneDrive, included in Office 365, enables you to store your files and folders online, and share them as you see fit**. You can work together with people (for work or fun), and coauthor files that are stored in OneDrive. You can also access your files across all your devices (your PC, phone, and tablet). [Manage sharing in OneDrive](https://docs.microsoft.com/OneDrive/manage-sharing).
+
+**But did you know there are good security reasons to use Windows Defender Antivirus together with Office 365**? Here are two:
+
+ 1. [You get ransomware protection and recovery](#ransomware-protection-and-recovery).
+
+ 2. [Integration means better protection](#integration-means-better-protection).
+
+Read the following sections to learn more.
+
+## Ransomware protection and recovery
+
+When you save your files to [OneDrive](https://docs.microsoft.com/onedrive), and [Windows Defender Antivirus](https://docs.microsoft.com/windows/security/threat-protection/windows-defender-antivirus/windows-defender-antivirus-in-windows-10) detects a ransomware threat on your device, the following things occur:
+
+1. **You are told about the threat**. (If your organization is using [Microsoft Defender Advanced Threat Protection](https://docs.microsoft.com/windows/security/threat-protection) (ATP), your security operations team is notified, too.)
+
+2. **Windows Defender Antivirus helps you (and your organization's security team) remove the ransomware** from your device(s). (If your organization is using Microsoft Defender ATP, your security operations team can determine whether other devices are infected and take appropriate action, too.)
+
+3. **You get the option to recover your files in OneDrive**. With the OneDrive Files Restore feature, you can recover your files in OneDrive to the state they were in before the ransomware attack occurred. See [Ransomware detection and recovering your files](https://support.office.com/article/0d90ec50-6bfd-40f4-acc7-b8c12c73637f).
+
+Think of the time and hassle this can save. 
+
+## Integration means better protection
+
+Office 365 Advanced Threat Protection integrated with Microsoft Defender Advanced Threat Protection means better protection for your organization. Here's how:
+
+- [Office 365 Advanced Threat Protection](https://docs.microsoft.com/microsoft-365/security/office-365-security/office-365-atp) safeguards your organization against malicious threats posed in email messages, email attachments, and links (URLs) in Office documents.
+
+    AND
+
+- [Microsoft Defender Advanced Threat Protection](https://docs.microsoft.com/windows/security/threat-protection) protects your devices from cyber threats, detects advanced attacks and data breaches, automates security incidents, and improves your security posture.
+
+    SO
+
+- Once integration is enabled, your security operations team can see a list of devices that are used by the recipients of any detected URLs or email messages, along with recent alerts for those devices, in the Microsoft Defender Security Center ([https://securitycenter.windows.com](https://securitycenter.windows.com)).
+
+If you haven't already done so, [integrate Office 365 Advanced Threat Protection with Microsoft Defender ATP](https://docs.microsoft.com/microsoft-365/security/office-365-security/integrate-office-365-ti-with-wdatp).
+
+## More good reasons to use OneDrive
+
+Protection from ransomware is one great reason to put your files in OneDrive. And there are several more good reasons, summarized in this video: <br/><br/>

-If the interface is not installed, you can add it in the **Add Roles and Features Wizard** at the **Features** step, under **Windows Defender Features** by selecting the **GUI for Windows Defender** option.
+6. (Only if necessary) [Uninstall Windows Defender Antivirus](#need-to-uninstall-windows-defender-antivirus)
+
+## Enable the user interface on Windows Server 2016 or 2019
+
+By default, Windows Defender Antivirus is installed and functional on Windows Server 2016 and Windows Server 2019. The user interface (GUI) is installed by default on some SKUs, but is not required because you can use PowerShell or other methods to manage Windows Defender Antivirus. And if the GUI is not installed on your server, you can add it by using the Add Roles and Features Wizard or PowerShell.
+
+### Turn on the GUI using the Add Roles and Features Wizard
+
+1. Refer to [this article](https://docs.microsoft.com/windows-server/administration/server-manager/install-or-uninstall-roles-role-services-or-features#install-roles-role-services-and-features-by-using-the-add-roles-and-features-wizard), and use the **Add Roles and Features Wizard**.
+
+2. When you get to the **Features** step of the wizard, under **Windows Defender Features**, select the **GUI for Windows Defender** option.
+
+In Windows Server 2016, the **Add Roles and Features Wizard** looks like this:
 
 ![Add roles and feature wizard showing the GUI for Windows Defender option](images/server-add-gui.png)
 
-See the [Install or uninstall roles, role services, or features](https://docs.microsoft.com/windows-server/administration/server-manager/install-or-uninstall-roles-role-services-or-features) topic for information on using the wizard.

+
+### Turn on the GUI using PowerShell
+
+The following PowerShell cmdlet will enable the interface: 
 
 ```PowerShell
 Install-WindowsFeature -Name Windows-Defender-GUI
 ```
 
-To hide the interface, use the **Remove Roles and Features Wizard** and deselect the **GUI for Windows Defender** option at the **Features** step, or use the following PowerShell cmdlet:
+## Install Windows Defender Antivirus on Windows Server 2016 or 2019
 
+You can use either the **Add Roles and Features Wizard** or PowerShell to install Windows Defender Antivirus.
 
-```PowerShell
