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 mostly match
prevents

Hardened configuration baselines and reviews directly prevent permissive CSP or cross-domain policies.

PR.PS-06 mostly match
prevents

Secure SDLC activities include review and testing of web security policies to avoid untrusted domains.

ID.RA-01 partial match
prevents

Vulnerability identification processes can surface permissive policy misconfigurations.

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 can detect overly permissive cross-domain policies but does not prevent their initial introduction.

A.8.20 Networks security partial match
degrades

Network security policies can restrict cross-domain communication but do not specifically mandate strict CSP or cross-domain policy configuration.

A.8.21 Security of network services partial match
degrades

Security of network services includes defining allowed endpoints, which can limit untrusted domains but does not directly address web-client policy files.

A.8.23 Web filtering partial match
degrades

Web filtering can block untrusted domains at the network level, partially mitigating permissive cross-domain policies.

A.8.26 Application security requirements partial match
prevents

Application security requirements should specify secure CSP and cross-domain policy settings, directly addressing the weakness.

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

Secure architecture principles include defining trust boundaries, which can reduce permissive cross-domain allowances.
