Notes

  • To test AppLocker rules for a nested group, you should specify a representative member of the nested group for the User parameter. For example, a rule that allows the Everyone group to run calc.exe may not appear to apply correctly when you specify the nested Finance group for the User parameter. Instead, you should specify a representative member of the Finance group for the User parameter.

Examples

EXAMPLE 1

C:\PS>Test-AppLockerPolicy -XMLPolicy C:\Policy.xml -Path C:\Windows\System32\calc.exe,  C:\Windows\System32\notepad.exe -User Everyone

Uses the AppLocker policy in C:\Policy.xml to test whether calc.exe and notepad.exe are allowed to run for users who are members of the Everyone group. If you do not specify a group, the Everyone group is used by default.

EXAMPLE 2

C:\PS>Get-ChildItem C:\Windows\System32 -filter *.exe -recurse | Convert-Path | Test-AppLockerPolicy c:\Policy.xml -User S-1-5-21-3165297888-301567370-576410423-1103 -Filter DeniedByDefault

Gets the list of all executable files under C:\Windows\System32, obtains the full path for each file using the Convert-Path cmdlet, and then uses the AppLocker policy specified in C:\Policy.xml to test whether the user with the specified SID is denied access to run the files by default. A policy decision of DeniedByDefault occurs when there are rules in the rule collection, but there are no explicit allow or deny rule that apply to the specified file and user.

EXAMPLE 3

C:\PS>Get-AppLockerPolicy -Local | Test-AppLockerPolicy -Path C:\Windows\System32\*.exe -User domain\saradavis -Filter Denied | Format-List -Property Path > C:\DeniedFiles.txt

Gets the local AppLocker policy, uses the policy to determine which executables in C:\Windows\System32 Sara Davis is explicitly denied access to run, and then redirects the list to a text file.
