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 correct UI behavior matching user intent via design, requirements, and testing.

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

Security testing in development and acceptance validates that UI actions match user intent and requirements.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes UI/UX requirements and testing that directly prevent the interface from executing the wrong action.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly capture correct user-action mapping and expected behavior.

A.8.28 Secure coding partial match
prevents

Secure coding practices enforce correct control-flow and input-to-action mapping in the UI layer.

A.8.32 Change management partial match
prevents

Change management can catch UI defects before release but does not itself define correct action semantics.
