Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces authorization decisions on resource access, blocking the forceful browsing enabled by the missing/incorrect checks in the Drupal module.

prevent

Limits granted privileges so that even successful forceful browsing yields minimal additional access beyond what the flawed module permits.

prevent

Enforces information flow rules between subjects and objects, providing an additional layer that can deny the unauthorized file retrieval paths.

PR.AA-05 mostly match
prevents

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.

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

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.

prevents

Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.

prevents

By tying access rights to identity, device, location and classification, the control reduces the likelihood that an authorization decision will be based on an incorrect or bypassed policy.
