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-03 mostly match
prevents

Password-strength policy enforcement directly blocks empty passwords while authentication covers far more than credential storage.

PR.PS-01 mostly match
prevents

Hardened configuration baselines and reviews prevent empty-password settings, yet configuration management addresses many other settings beyond credentials.

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.

A.8.9 Configuration management mostly match
prevents

Configuration management processes would normally detect and correct insecure empty-password settings.

A.5.17 Authentication information partial match
prevents

Requires secure handling and protection of authentication credentials, directly addressing empty passwords in config files.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes controls that should prevent shipping empty passwords in configuration artifacts.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly forbid hard-coded or empty credentials.

A.8.5 Secure authentication partial match
prevents

Mandates secure authentication mechanisms, preventing use of empty or weak passwords.
