Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

IA-12 Identity Proofing good match

Identity proofing at appropriate assurance levels ensures forgotten-password recovery cannot succeed without strong verification of the user.

IA-5 Authenticator Management good match

Authenticator management requires secure distribution, reset, and verification procedures that directly address weak password recovery flows.

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 partial match

blocks

Credential lifecycle management directly includes password reset/recovery flows.

PR.AA-02 partial match

blocks

Identity proofing is the core control that prevents weak or bypassed recovery mechanisms.

PR.AA-03 partial match

blocks

Authentication policy covers strength/MFA but does not address recovery path weaknesses.

PR.PS-06 partial match

blocks

Secure SDLC reduces implementation flaws but is not specific to password-recovery design.
