Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-732

Procedures support proper permission assignment for critical resources through documented controls.

addresses: CWE-732

Attribute management for resources provides a mechanism to assign and maintain correct permissions based on security labels.

addresses: CWE-732

Prevents overly permissive assignments to critical resources by limiting to task needs.

addresses: CWE-732

Training policy covers correct permission assignment, reducing the ability to exploit incorrect permission assignments for critical resources.

addresses: CWE-732

Training on permission management reduces incorrect permission assignments for critical resources.

addresses: CWE-732

Audit logs and logging tools are critical resources whose protection requires correct permission assignments to block unauthorized actions.

addresses: CWE-732

Assessments review permission assignments on critical resources to confirm correctness, mitigating exploitation via incorrect permissions.

addresses: CWE-732

Certification includes checking that permissions on critical resources are correctly assigned.

PR.AA-05 full match
prevents

Directly requires defining, enforcing, and reviewing access permissions and least privilege on resources.

PR.PS-01 mostly match
prevents

Hardened baselines and configuration management explicitly include correct permission settings for critical 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.

prevents

By requiring owners to determine and document the exact permissions needed for each asset, the control reduces the likelihood that default or overly permissive file and resource permissions will be left in place.

prevents

Documented provisioning and revocation procedures reduce the chance that critical resources retain overly permissive default or leftover permissions after personnel changes.

prevents

Documented authorization, expiry rules, and audit logging of privileged accounts make it harder for critical resources to retain overly permissive or stale permission assignments.

prevents

Requiring explicit configuration of access controls and permissions for files, applications and services counters the assignment of overly permissive default or incorrect file-system rights.

prevents

Enforcing differentiated permissions on the source-code repository and program listings stops the assignment of overly broad default or inherited permissions to critical resources.

prevents

By defining and enforcing secure permission settings in configuration templates, the control reduces the likelihood that critical resources receive incorrect permission assignments.
