Mitigating Controls (NIST 800-53 r5) AI

IA-6 Authentication Feedback good match

Obscures authentication feedback so that success/failure differences are not observable to attackers.

SI-11 Error Handling good match

Requires error messages to avoid revealing exploitable details, directly stopping observable response discrepancies.

AC-4 Information Flow Enforcement partial match

Information flow enforcement can block responses that would otherwise disclose internal state to unauthorized parties.

SC-7 Boundary Protection partial match

Boundary protection monitors and filters outbound responses that could leak internal state.
