Mitigating Controls (NIST 800-53 r5) AI
Requires a tamper-proof, always-invoked reference monitor that cannot be bypassed by client-side logic.
Enforces all access decisions on the server according to policy rather than trusting client-supplied enforcement.
Enforces information-flow rules at the server boundary instead of delegating them to the client.
Monitors and controls all external and key internal interfaces so that server-side policy cannot be off-loaded to clients.

Secure architecture principles discourage client-side trust but do not directly address this weakness.
Security testing can detect client-side enforcement but is not the primary mitigation.
Information access restriction is undermined when the client is trusted to enforce it.
Secure development lifecycle mandates server-side validation and prevents reliance on client enforcement.
Application security requirements explicitly call for server-side enforcement of security mechanisms.
Secure coding standards require server-side checks and reject client-only enforcement.
