![]() ![]() ![]() AppLocker takes the approach of denying all executables from running unless they have specifically been whitelisted and allowed.ĪppLocker is available in Windows Server 2008 R2 and newer, and Windows 7 Enterprise edition or newer on the client side. Then you can continue by exporting it as xml and pasting each rule collection into the Intune profile again.We can implement AppLocker rules using group policy in a Windows domain to limit the execution of arbitrary executable files. Once you run the query you get all files that are recognized by AppLocker (or Defender Application Control):ĭepending on how you use AppLocker you can extract information about either paths, file names, signature, or file hashes to enhance your policy which you would then edit in either GPMC or GPEdit. by changing the EventTime filter to cover more days in the past. You can modify the query at any time, e.g. Now we head over to the Microsoft Defender Security Center selecting the Advanced hunting sub-menu. ![]() So you might want to use AppLocker in audit mode first. Although it might seem obvious please remember that deploying any kind of application control in enforced mode could break things without testing it first. Once you have added all rule collection types it will look something like this:ĭon’t forget to assign the profile to all users and/or devices you want to target. The Value text field must contain each rule collection xml section including and as marked here in Notepad++: Here’s an example for the EXE rule collection: Vendor/MSFT/AppLocker/ApplicationLaunchRestrictions/Native/DLL/Policyįind out more in the official AppLocker CSP documentation:ĭata type has to be set to “String”, Value equals each section from the AppLocker xml. Vendor/MSFT/AppLocker/ApplicationLaunchRestrictions/Native/StoreApps/Policy Vendor/MSFT/AppLocker/ApplicationLaunchRestrictions/Native/Script/Policy Vendor/MSFT/AppLocker/ApplicationLaunchRestrictions/Native/MSI/Policy Vendor/MSFT/AppLocker/ApplicationLaunchRestrictions/Native/EXE/Policy Now we need to jump over to the Intune console to create a new Windows 10 configuration profile using the “Custom” profile type:įor each of the five different rule collections a distinct entry must be added. Even in a cloud-only scenario with Azure AD joined clients you can still use the latter to build the policy. Configuration in Intuneįirst export your AppLocker configuration from either the Group Policy Management Console in Active Directory or from your local GPEdit Console. I will focus on how you can shift it to Intune for deployment and Microsoft Defender ATP’s Advanced Hunting capabilities for monitoring and policy refinement. ![]() In this post I assume that you are already some kind of familiar with AppLocker. It is one of my recommendations for a secure Windows 10 baseline. Although it is not the best solution from a technical point of view (there’s Windows Defender Application Control including TPM-enforced policy signing) it is still a good way to build a quick solution to stop users from installing software or executing unwanted applications. In this post I will give you a quick overview about cloud configuration of AppLocker using Intune and MDATP.ĪppLocker has been with us for quite some time now reaching back all the way to good old Windows 7. ![]()
