Mitigating Controls (NIST 800-53 r5) AI

SC-13 Cryptographic Protection good match

Mandates use of cryptography to protect sensitive information, preventing its unencrypted storage in environment variables.

SC-28 Protection of Information at Rest good match

Requires confidentiality protection (typically encryption) for information at rest, directly stopping cleartext storage of sensitive data in environment variables.

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.DS-01 partial match
blocks

Encryption and related protections for data-at-rest directly prevent cleartext env-var storage of secrets.

PR.PS-01 partial match
blocks

Hardened configuration baselines and management practices reduce the chance of secrets being left in environment variables.

PR.PS-06 partial match
blocks

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