Mitigating Controls (NIST 800-53 r5) AI
Access enforcement directly requires verifying ownership before granting access to resources.
Requiring access decisions to consider all relevant attributes includes ownership verification.
A reference monitor provides the tamperproof mechanism that can enforce ownership checks.
Associating ownership as a security attribute enables subsequent verification of resource ownership.

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.
Enforcing defined access permissions and authorizations directly prevents missing ownership verification for 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.
Access control policies can require ownership verification before granting access to critical resources.
Identity management processes can include verification of resource ownership during provisioning and access decisions.
Access rights reviews can enforce checks that only legitimate owners retain privileges over critical assets.
Privileged access rights assignment should verify ownership to prevent unauthorized elevation on critical resources.
Information access restriction mechanisms can implement ownership checks before allowing operations on protected resources.
Secure authentication can be extended to verify resource ownership in addition to user identity.
