Overview​

Control Type​

Detective

Test-MtAdGpoDenyAceDetails​

Returns details of GPO reports that include a Deny ACE.

Why This Test Matters​

  • Detective control: lists GPO reports that contain a Deny ACE which could block legitimate policy application.

Security Recommendation​

  • Review and minimize Deny ACE usage; remove unnecessary permissions to reduce risk.

How the Test Works​

  • Reads GPO state, selects reports where HasDenyAce is true, and outputs a Markdown table of such GPOs.
  • Test-MtAdGpoDenyAceCount.
