Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

IA-11 Re-authentication good match

Re-authentication explicitly requires users to prove identity before performing sensitive actions such as password changes.

IA-5 Authenticator Management good match

Authenticator management requires identity verification during password distribution and changes, directly stopping unverified password updates.

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 management practices directly enforce re-authentication for password changes.

PR.AA-03 partial match
