Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces access authorizations on the server, making client-side bypass ineffective.

IA-2 Identification and Authentication (Organizational Users) good match

Requires server-side identification and authentication of users before granting access.

Mitigating Controls (NIST CSF 2.0) AI

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.AA-03 full match
prevents

Server-enforced authentication directly prevents client-only checks from being bypassed.

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.8.5 Secure authentication full match
degrades

Requires server-side authentication mechanisms that directly prevent client-only checks.

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

Promotes secure architecture principles that reject client-only authentication designs.

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

Security testing can detect missing server-side authentication checks.

A.8.26 Application security requirements partial match
prevents

Defines application security requirements that include server-side authentication enforcement.

A.8.28 Secure coding partial match
prevents

Secure coding standards discourage reliance on client-side authentication logic.

A.8.3 Information access restriction partial match
mitigates

Enforces access restrictions that must be validated on the server, mitigating client-side bypass.
