# Windows application security
Cyber-criminals regularly gain access to valuable data by hacking applications. This can include “code injection” attacks, in which attackers insert malicious code that can tamper with data, or even destroy it. An application may have its security misconfigured, leaving open doors for hackers. Or vital customer and corporate information may leave sensitive data exposed. Windows protects your valuable data with layers of application security.

# Multi-factor Unlock
# Multi-factor unlock
Windows Hello for Business supports the use of a single credential (PIN and biometrics) for unlocking a device. Therefore, if any of those credentials are compromised (shoulder surfed), an attacker could gain access to the system.
Windows Hello for Business can be configured with multi-factor device unlock, by extending Windows Hello with trusted signals. Administrators can configure devices to request a combination of factors and trusted signals to unlock them.
Windows Hello for Business can be configured with *multi-factor unlock*, by extending Windows Hello with trusted signals. Administrators can configure devices to request a combination of factors and trusted signals to unlock them.
Which organizations can take advantage of Multi-factor unlock? Those who:
Multi-factor unlock is ideal for organizations that:
- Have expressed that PINs alone do not meet their security needs
- Have expressed that PINs alone don't meet their security needs
- Want to prevent Information Workers from sharing credentials
- Want their organizations to comply with regulatory two-factor authentication policy
- Want to retain the familiar Windows sign-in user experience and not settle for a custom solution
You enable multi-factor unlock using Group Policy. The **Configure device unlock factors** policy setting is located under **Computer Configuration\Administrative Templates\Windows Components\Windows Hello for Business**.
## The Basics: How it works
## How it works
First unlock factor credential provider and Second unlock credential provider are responsible for the bulk of the configuration. Each of these components contains a globally unique identifier (GUID) that represents a different Windows credential provider. With the policy setting enabled, users unlock the device using at least one credential provider from each category before Windows allows the user to proceed to their desktop.
**First unlock factor credential provider** and **Second unlock credential provider** are responsible for the bulk of the configuration. Each of these components contains a globally unique identifier (GUID) that represents a different Windows credential provider. With the policy setting enabled, users unlock the device using at least one credential provider from each category before Windows allows the user to proceed to their desktop.
The policy setting has three components:
* First unlock factor credential provider
* Second unlock factor credential provider
* Signal rules for device unlock
## Configuring Unlock Factors
- First unlock factor credential provider
- Second unlock factor credential provider
- Signal rules for device unlock
The **First unlock factor credential providers** and **Second unlock factor credential providers** portion of the policy setting each contain a comma separated list of credential providers.
## Configure unlock factors
Supported credential providers include:
The **First unlock factor credential providers** and **Second unlock factor credential providers** portion of the policy setting each contain a comma separated list of credential providers.
Supported credential providers include:
|Credential Provider| GUID|

>[!NOTE]
>Multifactor unlock does not support third-party credential providers or credential providers not listed in the above table.
The default credential providers for the **First unlock factor credential provider** include:
* PIN
* Fingerprint
* Facial Recognition
- PIN
- Fingerprint
- Facial Recognition
The default credential providers for the **Second unlock factor credential provider** include:
* Trusted Signal

Configure a comma separated list of credential provider GUIDs you want to use as first and second unlock factors. While a credential provider can appear in both lists, remember that a credential supported by that provider can only satisfy one of the unlock factors. Listed credential providers do not need to be in any specific order.
- Trusted Signal
- PIN
For example, if you include the PIN and fingerprint credential providers in both first and second factor lists, a user can use their fingerprint or PIN as the first unlock factor. However, whichever factor they used to satisfy the first unlock factor cannot be used to satisfy the second unlock factor. Each factor can therefore be used exactly once. The Trusted Signal provider can *only* be specified as part of the Second unlock factor credential provider list.

Whichever factor you use to satisfy the first unlock factor can't be used to satisfy the second unlock factor. Each factor can therefore be used exactly once. The Trusted Signal provider can *only* be specified as part of the Second unlock factor credential provider list.
## Configure Signal Rules for the Trusted Signal Credential Provider
The **Signal rules for device unlock** setting contains the rules the Trusted Signal credential provider uses to satisfy unlocking the device.
### Rule element
You represent signal rules in XML. Each signal rule has a starting and ending **rule** element that contains the **schemaVersion** attribute and value. The current supported schema version is 1.0.
**Example**
You represent signal rules in XML. Each signal rule has a starting and ending `rule` element that contains the `schemaVersion` attribute and value. The current supported schema version is `1.0`.
#### Example
```xml
<rule schemaVersion="1.0">
</rule>
```
### Signal element
Each rule element has a **signal** element. All signal elements have a **type** element and value. Windows 10, version 1709 or later supports the **ipConfig** and **bluetooth** type values.
Each rule element has a `signal` element. All signal elements have a `type` element and `value`. The values supported are:
|Attribute|Value|
|---------|-----|
| type| "bluetooth" or "ipConfig" (Windows 10, version 1709) or later|
| type| "wifi" (Windows 10, version 1803 or later)
- bluetooth
- ipConfig
- wifi
#### Bluetooth
You define the bluetooth signal with additional attributes in the signal element. The bluetooth configuration does not use any other elements. You can end the signal element with short ending tag "\/>".
You define the bluetooth signal with more attributes in the signal element. The bluetooth configuration doesn't use any other elements. You can end the signal element with short ending tag `/>`.
|Attribute|Value|Required|
|---------|-----|--------|
|type|"bluetooth"|yes|
|scenario|"Authentication"|yes|
|type|`bluetooth`|yes|
|scenario|`Authentication`|yes|
|classOfDevice|"*number*"|no|
|rssiMin|"*number*"|no|
|rssiMaxDelta|"*number*"|no|
**Example**
For example:
```xml
<rule schemaVersion="1.0">
<signal type="bluetooth" scenario="Authentication" classOfDevice="512" rssiMin="-10" rssiMaxDelta="-10"/>
</rule>

The **rssiMin** attribute value signal indicates the strength needed for the device to be considered "in-range". The default value of **-10** enables a user to move about an average size office or cubicle without triggering Windows to lock the device. The **rssiMaxDelta** has a default value of **-10**, which instruct Windows to lock the device once the signal strength weakens by more than measurement of 10.

The **rssiMaxDelta** has a default value of **-10**, which instruct Windows to lock the device once the signal strength weakens by more than measurement of 10.
RSSI measurements are relative and lower as the bluetooth signals between the two paired devices reduces. Therefore a measurement of 0 is stronger than -10, which is stronger than -60, which is an indicator the devices are moving further apart from each other.

## Deploying Multifactor Unlock
## Deploy Multifactor Unlock
>[!IMPORTANT]
>You need to remove all third party credential providers to ensure users cannot unlock their devices if they do not have the required factors. The fall back options are to use passwords or smart cards (both of which could be disabled as needed).
### How to configure Multifactor Unlock policy settings
You need at least a Windows 10, version 1709 or later workstation to run the Group Policy Management Console, which provides the latest Windows Hello for Business Group Policy settings, which includes multi-factor unlock. To run the Group Policy Management Console, you need to install the Remote Server Administration Tools for Windows. You can download these tools from the [Microsoft Download Center](https://www.microsoft.com/download/details.aspx?id=45520). Install the Remote Server Administration Tools for Windows on a computer running Windows 10, version 1709 or later.
Alternatively, you can create copy the .ADMX and .ADML files from a Windows 10, version 1703 to their respective language folder on a Windows Server or you can create a Group Policy Central Store and copy them their respective language folder. See [How to create and manage the Central Store for Group Policy Administrative Templates in Windows](/troubleshoot/windows-client/group-policy/create-and-manage-central-store) for more information.
### Create the Multifactor Unlock Group Policy object
The Group Policy object contains the policy settings needed to trigger Windows Hello for Business provisioning and to ensure Windows Hello for Business authentication certificates are automatically renewed.
>[!IMPORTANT]
> * PIN **must** be in at least one of the groups
> * Trusted signals **must** be combined with another credential provider
> * You cannot use the same unlock factor to satisfy both categories. Therefore, if you include any credential provider in both categories, it means it can satisfy either category, but not both.
> * The multifactor unlock feature is also supported via the Passport for Work CSP. See [Passport For Work CSP](/windows/client-management/mdm/passportforwork-csp) for more information.

# Secure the Windows boot process
*Applies to:*
- Windows 11
- Windows 10
- Windows 8.1
The Windows OS has many features to help protect you from malware, and it does an amazingly good job. Except for apps that businesses develop and use internally, all Microsoft Store apps must meet a series of requirements to be certified and included in the Microsoft Store. This certification process examines several criteria, including security, and is an effective means of preventing malware from entering the Microsoft Store. Even if a malicious app does get through, the Windows 10 OS includes a series of security features that can mitigate the effect. For instance, Microsoft Store apps are sandboxed and lack the privileges necessary to access user data or change system settings.

Windows 10 includes Group Policy-configurable “Process Mitigation Options” that add advanced protections against memory-based attacks, that is, attacks where malware manipulates memory to gain control of a system. For example, malware might attempt to use buffer overruns to inject malicious executable code into memory, but Process Mitigation Options can prevent the running of the malicious code.

This phenomenon is also known as the consumerization of IT.
Users want to have the best productivity experience when accessing corporate applications and working on organization data from their devices. That means they won't tolerate being prompted to enter their work credentials each time they access an application or a file server. From a security perspective, it also means that users will manipulate corporate credentials and corporate data on unmanaged devices.

Today's computing threat landscape is increasing at a speed never encountered before. The sophistication of criminal attacks is growing, and there's no doubt that malware now targets both consumers and professionals in all industries.
During recent years, one particular category of threat has become prevalent: advanced persistent threats (APTs). The term APT is commonly used to describe any attack that seems to target individual organizations on an on-going basis. In fact, this type of attack typically involves determined adversaries who may use any methods or techniques necessary.
With the BYOD phenomena, a poorly maintained device represents a target of choice. For an attacker, it’s an easy way to breach the security network perimeter, gain access to, and then steal high-value assets.
With the BYOD phenomena, a poorly maintained device represents a target of choice. For an attacker, it's an easy way to breach the security network perimeter, gain access to, and then steal high-value assets.
The attackers target individuals, not specifically because of who they are, but because of who they work for. An infected device will bring malware into an organization, even if the organization has hardened the perimeter of networks or has invested in its defensive posture. A defensive strategy isn't sufficient against these threats.
### A different approach
Rather than the traditional focus on the prevention of compromise, an effective security strategy assumes that determined adversaries will successfully breach any defenses. It means that it’s necessary to shift focus away from preventative security controls to detection of, and response to, security issues. The implementation of the risk management strategy, therefore, balances investment in prevention, detection, and response.

An MDM solution asks the device to send device health information and forward the health encrypted blob to the remote health attestation service. The remote health attestation service verifies device health data, checks that MDM is communicating to the same device, and then issues a device health report back to the MDM solution.
An MDM solution evaluates the health assertions and, depending on the health rules belonging to the organization, can decide if the device is healthy. If the device is healthy and compliant, MDM passes that information to the identity provider so the organization’s access control policy can be invoked to grant access.

Depending on the requirements and the sensitivity of the managed asset, device health status can be combined with user identity information when processing an access request. Access to content is then authorized to the appropriate level of trust. The Conditional Access engine may be structured to allow more verification as needed by the sensitivity of the managed asset. For example, if access to high-value data is requested, further security authentication may need to be established by querying the user to answer a phone call before access is granted.

The most basic protection is the Secure Boot feature, which is a standard part of the UEFI 2.2+ architecture. On a PC with conventional BIOS, anyone who can take control of the boot process can boot by using an alternative OS loader, and potentially gain access to system resources. When Secure Boot is enabled, you can boot using only an OS loader that’s signed using a certificate stored in the UEFI Secure Boot DB. Naturally, the Microsoft certificate used to digitally sign the Windows 10 OS loaders are in that store, which allows UEFI to validate the certificate as part of its security policy. Secure Boot must be enabled by default on all computers that are certified for Windows 10 under the Windows Hardware Compatibility Program.

Secure Boot is a UEFI firmware-based feature, which allows for the signing and verification of critical boot files and drivers at boot time. Secure Boot checks signature values of the Windows Boot Manager, BCD store, Windows OS loader file, and other boot critical DLLs at boot time before the system is allowed to fully boot into a usable operating system by using policies that are defined by the OEM at build time. Secure Boot prevents many types of boot-based rootkit, malware, and other security-related attacks against the Windows platform. Secure Boot protects the operating system boot process whether booting from local hard disk, USB, PXE, or DVD, or into full Windows or Windows Recovery Environment (RE).
Secure Boot protects the boot environment of a Windows 10 installation by verifying the signatures of the critical boot components to confirm malicious activity didn't compromise them. Secure Boot protection ends after the Windows kernel file (ntoskrnl.exe) has been loaded.

Because the operating system hasn’t started yet, and because Windows needs to boot as quickly as possible, ELAM has a simple task: Examine every boot driver and determine whether it is on the list of trusted drivers. If it’s not trusted, Windows won’t load it.

This attack-free state is accomplished by using Hyper-V and the new virtualization-based security feature to create a protected container where trusted code and secrets are isolated from the Windows kernel. This accomplishment means that even if the Windows kernel is compromised, an attacker has no way to read and extract the data required to initiate a PtH attack.

Similarly, on corporate fully managed workstations, where applications are installed by using a distribution tool like Microsoft Configuration Manager, Intune, or any third-party device management, then Device Guard is applicable. In that type of scenario, the organization has a good idea of the software that an average user is running.
It could be challenging to use Device Guard on corporate, lightly managed workstations where the user is typically allowed to install software on their own. When an organization offers great flexibility, it’s difficult to run Device Guard in enforcement mode. Nevertheless, Device Guard can be run in Audit mode, and in that case, the event log will contain a record of any binaries that violated the Device Guard policy. When Device Guard is used in Audit mode, organizations can get rich data about drivers and applications that users install and run.

Before you can benefit from the protection included in Device Guard, Code Integrity policy must be created by using tools provided by Microsoft, but the policy can be deployed with common management tools, like Group Policy. The Code Integrity policy is a binary-encoded XML document that includes configuration settings for both the User and Kernel-modes of Windows 10, along with restrictions on Windows 10 script hosts. Device Guard Code Integrity policy restricts what code can run on a device.

A solution that uses MDM and the Health Attestation Service consists of three main parts:
1. A device with health attestation enabled. This enablement will be done as a part of enrollment with an MDM provider (health attestation will be disabled by default).
2. After this service is enabled, and every boot thereafter, the device will send health measurements to the Health Attestation Service hosted by Microsoft, and it will receive a health attestation blob in return.
3. At any point after this cycle, an MDM server can request the health attestation blob from the device and ask Health Attestation Service to decrypt the content and validate that it’s been attested.

### What format is used for forwarded events?
WEF has two modes for forwarded events. The default is “Rendered Text” that includes the textual description of the event as you would see it in Event Viewer. This description's inclusion means that the event size is effectively doubled or tripled depending on the size of the rendered description. The alternative mode is “Events” (also sometimes referred to as “Binary” format) – which is just the event XML itself sent in binary XML format (as it would be written to the evtx file.) This format is compact and can more than double the event volume a single WEC server can accommodate.
