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 directly requires that only the minimal necessary privileges are assigned to each actor.

AC-2 Account Management partial match

Account management defines and authorizes the exact privileges granted to each account or role.

AC-5 Separation of Duties partial match

Separation of duties constrains which privilege combinations may be assigned to any actor.

Mitigating Controls (NIST CSF 2.0) AI

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 full match
prevents

Directly enforces least-privilege policy definition, management, and review that prevents incorrect privilege assignments.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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

A.5.18 Access rights mostly match
prevents

The access-rights control governs the entire lifecycle of privilege assignment, directly eliminating incorrect assignments.

A.8.2 Privileged access rights mostly match
prevents

Privileged-access-rights control explicitly requires least-privilege assignment and ongoing validation, directly mitigating CWE-266.

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.5.3 Segregation of duties partial match
mitigates

Segregation of duties reduces blast radius of any single incorrect privilege but does not prevent the assignment itself.

A.8.18 Use of privileged utility programs partial match
mitigates

Restricting privileged utility programs limits exposure from over-privileged accounts but does not address how privileges are assigned.

A.8.3 Information access restriction partial match
prevents

By tying access rights to identity, device, location and classification, the control reduces the likelihood that an authorization decision will be based on an incorrect or bypassed policy.
