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-06 mostly match
prevents

Secure SDLC practices directly require implementing frame-ancestors / X-Frame-Options controls that prevent this weakness.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect missing frame protections, but does not itself implement the control.

A.8.23 Web filtering partial match
degrades

Web filtering can block or sandbox untrusted frames, but does not enforce application-level frame-busting or CSP.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate frame-ancestors / X-Frame-Options, directly addressing UI redressing risks.

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

Secure architecture principles include isolation of UI layers and proper use of browser security controls.

A.8.28 Secure coding partial match
prevents

Secure coding practices directly require implementation of frame-busting headers or CSP frame-ancestors directives.
