Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly enforces access control policies on system files, blocking unauthorized reads of password hashes when permissions are misassigned.
Requires assignment of only the minimum necessary permissions to critical resources such as password hash files, directly addressing CWE-732.
Mandates secure configuration settings that include proper file permissions on sensitive system resources to prevent local disclosure.

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.
Documented provisioning and revocation procedures reduce the chance that critical resources retain overly permissive default or leftover permissions after personnel changes.
Documented authorization, expiry rules, and audit logging of privileged accounts make it harder for critical resources to retain overly permissive or stale permission assignments.
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.
Enforcing differentiated permissions on the source-code repository and program listings stops the assignment of overly broad default or inherited permissions to critical resources.
By defining and enforcing secure permission settings in configuration templates, the control reduces the likelihood that critical resources receive incorrect permission assignments.
