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 prevent design flaws that place server security enforcement on the client.

PR.AA-05 partial match
prevents

Proper policy-based enforcement of authorizations implies server-side controls rather than client-only 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.

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

Secure architecture principles discourage client-side trust but do not directly address this weakness.

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

Security testing can detect client-side enforcement but is not the primary mitigation.

A.8.3 Information access restriction mostly match
prevents

Information access restriction is undermined when the client is trusted to enforce it.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates server-side validation and prevents reliance on client enforcement.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for server-side enforcement of security mechanisms.

A.8.28 Secure coding partial match
prevents

Secure coding standards require server-side checks and reject client-only enforcement.
