Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

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

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

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

Limits granted privileges so that even a bypassed check affects fewer resources.

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.

blocks

A.5.1 only requires the existence of an overarching policy and topic-specific policies (including on access control); it does not itself perform or enforce any authorization check, so the CWE-285 weakness can still be exploited.

blocks

Mapping access rights to information classification and business requirements forces correct enforcement of authorization decisions, blocking the incorrect authorization weakness at the policy and implementation stage.

finds

Independent reviewers evaluate whether authorization logic matches policy, thereby reducing the window in which incorrect or missing authorization checks remain in production.

finds

By requiring managers to verify that authorization decisions match policy and to remediate deviations, the control limits the persistence of incorrect or missing authorization checks.

blocks

Requiring authorization processes and privilege assignments to be specified during project initiation prevents downstream components from receiving overly broad or incorrect rights that would allow unauthorized actions.

blocks

A.8.3 directly mandates and configures the authorization mechanisms (identity/group rights, dynamic access rules, isolation, credential enforcement) that stop CWE-285 exploitation; the bounded remainder is non-authorization exposure vectors such as error messages or observable discrepancies.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-285, a class-level weakness. Rules are authored against its narrower children: CWE-552.
