Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Properly tuned thresholds and lock durations in the unsuccessful logon control stop an overly sensitive lockout from being introduced or exploited for DoS.

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-01 mostly match
prevents

Credential management policies directly govern lockout thresholds and reset procedures.

PR.AA-03 mostly match
prevents

Authentication policies include lockout parameters that must not be overly restrictive.

PR.AA-05 mostly match
prevents

Authorization policy definition and review encompass account lockout rules and exceptions.

DE.CM-03 partial match
prevents

Monitoring can detect resulting lockouts but does not prevent an overly restrictive mechanism.

degrades

Access control policy should define lockout thresholds and recovery procedures to avoid overly restrictive denial-of-service.

degrades

Authentication information management includes setting lockout parameters that balance security against accidental lockouts.

degrades

Access rights administration must include procedures for unlocking accounts and reviewing lockout events.

degrades

Secure authentication mechanisms directly specify lockout thresholds, unlock processes, and monitoring to prevent abuse.

A.8.15 Logging none match
none

Logging of authentication events enables detection of lockout abuse but does not prevent the weakness itself.

none

Monitoring can detect excessive lockouts but does not define or enforce appropriate lockout parameters.
