Mitigating Controls (NIST 800-53 r5) AI

AC-12 Session Termination good match
prevent

Directly requires session termination after inactivity or defined timeout, eliminating the exact flaw that leaves sessions valid for impersonation.

IA-11 Re-authentication partial match
prevent

Forces periodic re-authentication, limiting the window an attacker can exploit a non-expired session.

SC-23 Session Authenticity minimal match
prevent

Requires protection of session authenticity, which can reduce successful reuse of stale session tokens.

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-01 mostly match
prevents

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

PR.AA-05 mostly match
prevents

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

PR.AA-03 partial match
prevents

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

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 none match
none

Automatic termination of inactive sessions and limits on connection duration shrink the window during which a hijacked or unattended authenticated session can be exploited.
