AppLocker Monitoring

Hello there,

I am trying to help logs from a aplication called AppLocker running on Windows.

The logs of this application can only be viewed at the detailed tab of the event view on xml format.

Is there any specific method or tweak to set up to collect and parse data from the detailed view?

Thanks-

Hello Wellington,

We just went through getting some AppLocker logs into Splunk today. We deployed the following paths to our inputs.conf on our Windows Servers.

[WinEventLog://Microsoft-Windows-AppLocker/EXE and DLL]
disabled = 0

[WinEventLog://Microsoft-Windows-AppLocker/MSI and Script]
disabled = 0

[WinEventLog://Microsoft-Windows-AppLocker/Packaged app-Deployment]
disabled = 0

[WinEventLog://Microsoft-Windows-AppLocker/Packaged app-Execution]
disabled = 0

So far we are using this in audit mode. A simple useful search we created was

source=AppLocker index=main EventCode=8003 OR EventCode=8006 | rex field=Message "(?.*)was allowed to run but would have been prevented from running if the AppLocker policy were enforced." | table time blockedapp User host

This created a table of time, application that would have been blocked, user, and host.
