Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces approved authorizations on files and resources so overly permissive defaults cannot be exploited.

AC-6 Least Privilege good match

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

CM-6 Configuration Settings good match

Requires documented, restrictive configuration settings that cover file and directory permissions.

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.

CM-5 Access Restrictions for Change partial match

Enforces access restrictions on changes, including permission settings applied during installation or configuration.

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-01 full match
prevents

Hardened baselines and configuration management explicitly require correct default file permissions.

ID.AM-08 partial match
prevents

Lifecycle management can encompass permission settings, yet the control is too broad to specifically mitigate incorrect defaults.

PR.PS-06 partial match
prevents

Secure SDLC practices include establishing secure defaults, but address only the development-phase portion of the weakness.

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.8.9 Configuration management mostly match
prevents

Standard templates that restrict access to utility programs and host parameter settings prevent the assignment of overly permissive default permissions on critical resources.

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.

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.
