Windows Defender Application Control (WDAC) basics

Windows Defender Application Control, like Windows AppLocker is a way to control what executes on your Windows 10 Professional and Enterprise workstation. For more information have a look at this article from Microsoft:

Windows Defender Application Control and AppLocker Overview

You can easily configure WDAC using PowerShell and Microsoft provides a number of example policies that you can use to get started. This video will demonstrate that process on a stand alone Windows 10 Enterprise workstation:

Both WDAC and AppLocker can be used together but the recommendation is use WDAC as it is a more modern approach to whitelisting and has greater security controls and enforcements.

You can also deploy WDAC using Intune and Endpoint Manager which I’ll look to demonstrate in an upcoming article.

So, much like AppLocker, you can use WDAC to prevent executables on your Windows 10 environment. This is a great way to minimise the risk of ransomware and should be part of your defence in depth strategy.
