Mitigating Controls (NIST 800-53 r5) AI

SC-23 Session Authenticity good match

Requires protection of session authenticity, which directly stops an attacker from using a stolen or fixed session identifier after authentication.

AC-12 Session Termination partial match

Limits the lifetime of any session (fixed or not), thereby reducing the window during which a stolen identifier remains usable.

AC-3 Access Enforcement partial match

Enforces that only properly authorized (i.e., freshly authenticated) sessions can access resources, making a pre-existing fixed session ID unusable.

IA-11 Re-authentication partial match

Forces re-authentication under defined conditions, which should result in issuance of a fresh session identifier and invalidation of any prior one.

PR.AA-01 partial match
blocks

Managing identities and credentials includes handling session identifiers as temporary credentials that must be invalidated on re-authentication.

PR.AA-03 partial match
blocks

Proper authentication processes must invalidate prior session identifiers to prevent fixation attacks.

PR.AA-04 partial match
blocks

Protecting and verifying identity assertions encompasses secure handling and regeneration of session tokens.

PR.PS-01 partial match
blocks

Configuration baselines can enforce session regeneration and timeout settings that block fixation.
