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

Requires least-privilege defaults so that installed files are not world-writable by default.

CM-6 Configuration Settings good match

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

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.PS-01 full match
prevents

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

PR.AA-05 mostly match
prevents

Defining and enforcing least-privilege access permissions directly prevents overly permissive defaults at install time.

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.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.
