![]() APPLOCKER GROUP POLICY SOFTWAREThink "whitelist."ĪppLocker is the successor to Software Restriction Policies (SRP) found in earlier Windows versions. ![]() Before you enable the GPOs, configure AppLocker so that it runs in Audit Only enforcement mode, which allows you to use Event Viewer to see the result of applying the policy without actually restricting anything on the target systems. This will prevent incomplete policies from being applied by Group Policy to computer accounts in the OUs linked to these GPOs. When creating AppLocker GPOs for production, disable them until you've configured all your AppLocker rules. You wouldn't want to create a policy, only to discover later that a key application is being blocked from running. Test before deploying.Īlways try your AppLocker policies in a test environment before using them in your production network. If you decide to do this, you can disable the user configuration settings of these GPOs in the Group Policy Management Console (GPMC) to speed up processing of these policies. Consider creating GPOs dedicated to this purpose that contain only AppLocker policy settings. This means you should configure AppLocker policies only within Group Policy Objects (GPOs) linked to organizational units (OUs) that have computer accounts in them - not user Âaccounts. Plan Group Policy properly.ĪppLocker policies are per-machine Group Policy settings, not per-user settings. Here are six tips to ease the process of configuring AppLocker for your environment. If you don't do it right, users might not be able to log on. This is useful for locking down computers, but AppLocker can be tricky to configure. APPLOCKER GROUP POLICY INSTALLThen you can continue by exporting it as xml and pasting each rule collection into the Intune profile again.The AppLocker feature in Microsoft Windows 7 Professional lets administrators control which applications and scripts users can install and load on their computers. 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 APPLOCKER GROUP POLICY WINDOWS 10Now 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. ![]()
