Mitigating Controls (NIST 800-53 r5) AI

AC-16 Security and Privacy Attributes good match

Associating and preserving security attributes (including permissions) with objects reduces the chance they are lost or weakened on copy/restore/share.

AC-3 Access Enforcement partial match

Enforcing approved authorizations for access directly stops objects from receiving or retaining less-restrictive permissions than intended.

AC-6 Least Privilege partial match

Least-privilege assignments limit the blast radius when permissions are incorrectly relaxed during copy/restore/share operations.
