What this checks and how to fix it
Section titled “What this checks and how to fix it”Inherited object type GUIDs define which descendant object classes an inheritable ACE targets.
- Delegation scope visibility: Helps show how precisely ACE inheritance is scoped
- Privilege impact analysis: Broad inheritance can extend powerful rights to many child objects
- Configuration review: Distinct inherited object types reveal the variety of object classes affected by delegations
Control Type
Section titled “Control Type”Operational
Security Recommendation
Section titled “Security Recommendation”- Review inherited ACEs that target sensitive descendant object classes
- Prefer precise scoping over overly broad inheritance where possible
- Validate that inheritance design matches your delegation model and administrative boundaries
How the Test Works
Section titled “How the Test Works”This test reads $adState.DaclEntries, filters for InheritedObjectType GUIDs that are not the all-zero default value, and counts the distinct GUIDs present.
