Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

AC-12 Session Termination good match

AC-12 directly requires automatic session termination after a defined period, structurally preventing reuse of expired session identifiers.

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 partial match
blocks

Credential lifecycle management directly includes enforcing session expiration to prevent reuse.

PR.AA-03 partial match
blocks

Authentication mechanisms can incorporate session timeout checks but do not inherently address expiration policy.

PR.AA-05 partial match
blocks

Authorization policy enforcement and review covers terminating stale sessions to limit access scope.
