Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly requires automatic session termination that invalidates the session identifier, blocking reuse by another authenticated user.
Protects session authenticity by ensuring session identifiers cannot be fixed or replayed to impersonate another user.
Forces re-authentication before sensitive actions, limiting the window in which a captured or fixed session ID remains usable.
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.
Proper authentication processes must invalidate prior session identifiers to prevent fixation attacks.
Managing identities and credentials includes handling session identifiers as temporary credentials that must be invalidated on re-authentication.
Protecting and verifying identity assertions encompasses secure handling and regeneration of session tokens.
Configuration baselines can enforce session regeneration and timeout settings that block fixation.
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.
Security testing can detect session-fixation issues, yet the weakness absence does not replace comprehensive testing.
Access-control policy can mandate session invalidation on re-authentication, but does not prescribe the technical mechanism.
Identity-management procedures can require new session tokens after login, yet the control is broader than session handling.
Authentication-information rules can include session-token lifecycle requirements, but the control focuses on credential management.
Secure-SDLC requirement can embed session-fixation checks, but eliminating the weakness does not satisfy the full SDLC control.
Application-security requirements can specify session handling, yet the weakness fix alone does not meet the broader requirement.
