Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Authenticator management requires verification of identity at initial distribution and secure handling that directly stops default passwords from remaining in use.

Configuration settings establish the most restrictive secure baselines, which include changing or disabling default passwords.

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 full match
prevents

Credential management directly requires replacing default passwords with unique, strong credentials.

PR.PS-01 mostly match
prevents

Hardened configuration baselines explicitly prohibit default passwords, covering most of the weakness but not all identity-management aspects.

ID.RA-01 partial match
prevents

Vulnerability scanning will discover default-password instances, enabling remediation, yet does not itself prevent their initial use.

PR.AA-03 partial match
prevents

Authentication policies can enforce non-default passwords but do not address the full scope of credential lifecycle.

PR.AA-05 partial match
prevents

Authorization policies assume credentials already exist and are not default; least-privilege helps limit impact but does not prevent defaults.

prevents

Mandates secure handling and change of authentication secrets, directly addressing default passwords.

prevents

Configuration management processes typically enforce changing defaults during hardening.

mitigates

Requires secure authentication mechanisms, which includes replacing or disabling default credentials.
