Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

AC-3 directly requires correct enforcement of authorization decisions on every access request, structurally preventing incorrect checks.

AC-24 Access Control Decisions good match

AC-24 ensures access-control decisions are made and applied consistently, reducing the chance of an incorrect authorization result.

AC-25 Reference Monitor good match

A reference monitor that is always invoked and tamper-proof forces every authorization decision through a verified, correct path.

AC-6 Least Privilege good match

Least privilege requires that only the minimal necessary permissions are granted, which structurally prevents the definition and inheritance of overly broad permissions.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-05 mostly match
prevents

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.

PR.PS-01 partial match
prevents

Configuration management practices include establishing secure permission baselines that avoid insecure inheritance.

PR.PS-06 partial match
prevents

Secure SDLC practices would catch and prevent defining insecure inherited permissions during development.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing may detect permission issues but does not prevent insecure inheritance by design.

A.5.15 Access control partial match
prevents

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.

A.5.18 Access rights partial match
prevents

Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.

A.8.2 Privileged access rights partial match
degrades

Privileged access rights management can limit inheritance of excessive permissions but does not directly address insecure default permission inheritance.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle practices can include permission model reviews but do not guarantee secure inherited permissions.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture principles can incorporate least-privilege permission models but do not specifically mandate secure inheritance.
