Windows Defender Application Control (WDAC) is a feature in Microsoft Defender for Endpoint that helps prevent unapproved applications from running on your system. WDAC policies allow administrators to specify which applications are allowed to run based on various conditions, including the publisher. In this article, we will explore how to identify the publisher property in WDAC policies.
Understanding WDAC Policies
WDAC policies are XML files that define the rules for application control. These rules can be based on various conditions, such as file name, file hash, publisher, and more. WDAC policies can be created using the Group Policy Editor, PowerShell, or the MDM (Mobile Device Management) platform.
Identifying Publisher Property
The publisher property in WDAC policies refers to the digital signature of the software publisher. This property is used to identify the software vendor or publisher of an application. By specifying the publisher property in a WDAC rule, administrators can allow or block applications based on the software publisher's digital signature.
Creating a WDAC Policy with Publisher Property
To create a WDAC policy with the publisher property, you can use the following PowerShell command:
New-AppxPolicy -Name "MyAppPolicy" -DisplayName "My Application Policy" -AllowFromPublishers "Microsoft Corporation"
In this example, we create a new WDAC policy named "MyAppPolicy" and allow applications from the publisher "Microsoft Corporation" to run.
Viewing WDAC Policies
To view the WDAC policies on your system, you can use the following PowerShell command:
Get-AppxPolicy
This command will display a list of all the WDAC policies currently in effect on your system.
