AppLocker is a set of Group Policy settings that evolved from Software Restriction Policies, to restrict which applications can run on a corporate network, including the ability to restrict based on the application’s version number or publisher. This list contains generic methods of bypassing AppLocker. Placing files in writeable paths. The following folders are by default writable by normal users (depends on Windows version - This is from W10 1803).
In this post I will give you a quick overview about cloud configuration of AppLocker using Intune and MDATP.
AppLocker has been with us for quite some time now reaching back all the way to good old Windows 7. 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. It is one of my recommendations for a secure Windows 10 baseline. Izotope rx torrent for mac os.
In this post I assume that you are already some kind of familiar with AppLocker. 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.
Configuration in Intune
First export your AppLocker configuration from either the Group Policy Management Console in Active Directory or from your local GPEdit Console. Even in a cloud-only scenario with Azure AD joined clients you can still use the latter to build the policy. It will look something like this:
Windows Application Locker
Now we need to jump over to the Intune console to create a new Windows 10 configuration profile using the “Custom” profile type:
For each of the five different rule collections a distinct entry must be added. These are the OMA-URIs you have to use:
- AppLocker EXE:
./Vendor/MSFT/AppLocker/ApplicationLaunchRestrictions/Native/EXE/Policy - AppLocker MSI:
./Vendor/MSFT/AppLocker/ApplicationLaunchRestrictions/Native/MSI/Policy - AppLocker Script:
./Vendor/MSFT/AppLocker/ApplicationLaunchRestrictions/Native/Script/Policy - AppLocker Appx:
./Vendor/MSFT/AppLocker/ApplicationLaunchRestrictions/Native/StoreApps/Policy - AppLocker DLL:
./Vendor/MSFT/AppLocker/ApplicationLaunchRestrictions/Native/DLL/Policy
Find out more in the official AppLocker CSP documentation:
https://docs.microsoft.com/en-us/windows/client-management/mdm/applocker-csp
Data type has to be set to “String”, Value equals each <RuleCollection> section from the AppLocker xml. Here’s an example for the EXE rule collection:
The Value text field must contain each rule collection xml section including <RullCollection …> and </RuleCollection> as marked here in Notepad++:
Once you have added all rule collection types it will look something like this:

Don’t forget to assign the profile to all users and/or devices you want to target. Although it might seem obvious please remember that deploying any kind of application control in enforced mode could break things without testing it first. So you might want to use AppLocker in audit mode first.
Monitor AppLocker events in MDATP
Now we head over to the Microsoft Defender Security Center selecting the Advanced hunting sub-menu. There we add the following query:
Photoshop cs6 for mac os x. MiscEvents
| where EventTime > ago(14d) and
ActionType startswith 'AppControl'
| order by EventTime desc
Just paste it to the query text field:
You can modify the query at any time, e.g. by changing the EventTime filter to cover more days in the past. Once you run the query you get all files that are recognized by AppLocker (or Defender Application Control):
Depending 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. Then you can continue by exporting it as xml and pasting each rule collection into the Intune profile again.

Applocker is another Level of security and the purpose is to restrict or allow the access to software in specific group of users.
Today lot of application aren't need administrator access to run. As IT Pro this is a threat for your environment.
While install and configure Applocker can increase the cybersecurity and protect your data from any unathorise access.
If you are thinking why to use Applocker the answer is here.

You can use it to protected against unwanted software , Software standardization , Software management.
If you want to more details you can read the AppLocker policy use scenarios in Microsoft Docs.
Today i will install and Deploy through GPO Applocker in specific Servers.
Applocker can be deploy in the following Windows Versions
- Windows 10 Enterprise
- Windows Server 2012,2016,2019
So let's start !!
- Before start to implement Applocker you must be know exactly which Applications must be allow to run.
- This is the most important step because if you try to apply Applocker without note down what Applications must be allow then you will create lot of problems in your users and the daily operation of your company.
- In case that you are not sure 100% which is the Applications that must be allow you can use Applocker in Audit Mode to identify all the applications.
How to enable Applocker
Applocker Dll
- Login in the Domain Controller and open the Group Policy Management.
- Right click in the Organization Until that you want to create the Applocker Policy and select Create a GPO in this Domain and link it here.
