Mitigating Controls (NIST 800-53 r5) AI

AC-24 Access Control Decisions good match

Mandates that access-control decisions are made and applied to each request before access occurs.

AC-25 Reference Monitor good match

Requires a tamperproof, always-invoked reference monitor that performs authorization checks.

AC-3 Access Enforcement good match

Directly requires enforcement of approved authorizations for every access request, stopping improper or missing checks.

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.

PR.PS-06 mostly match
prevents

Secure SDLC practices catch and eliminate most authorization defects before release, yet a single broad outcome cannot address every design, role, and runtime facet of CWE-285.

PR.AA-01 partial match
prevents

PR.AA-01 supplies managed identities and access-request workflows that can support downstream authorization decisions, yet does nothing to enforce or verify authorization checks inside a product, leaving CWE-285 fully unaddressed by this control alone.

PR.IR-01 partial match
prevents

Network segmentation/zero-trust limits external reachability (partial prevention of exploitation) but leaves application-level authorization logic untouched, so the CWE remains fully introducible and only one facet of its risk is addressed.

PR.PS-05 none match
prevents

PR.PS-05 blocks unauthorized binaries/DNS while CWE-285 is an in-product authorization-check defect, so the control neither prevents the weakness nor removes any of its risk.

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.8.3 Information access restriction mostly match
prevents

Granular, policy-driven assignment of permissions and dynamic enforcement of those permissions prevent the incorrect or missing authorization decisions that lead to improper authorization flaws.

A.5.1 Policies for information security partial match
prevents

By requiring documented authorization rules and periodic policy reviews, the control makes it less likely that authorization decisions will be omitted or implemented inconsistently across applications.

A.5.15 Access control partial match
prevents

Access control policy directly prevents incorrect privilege assignment by defining who may receive which rights.

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.
