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.8.29 Security testing in development and acceptance mostly match
finds

Security testing may detect permission issues but does not prevent insecure inheritance by design.

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.8.2 Privileged access rights partial match
degrades

Privileged access rights management can limit inheritance of excessive permissions but does not directly address insecure default permission inheritance.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle practices can include permission model reviews but do not guarantee secure inherited permissions.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture principles can incorporate least-privilege permission models but do not specifically mandate secure inheritance.

A.8.28 Secure coding partial match
prevents

Secure coding standards can explicitly require setting restrictive permissions at object creation, directly mitigating insecure inheritance.
