Mitigating Controls (NIST 800-53 r5) AI

IA-5 Authenticator Management good match

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

SC-13 Cryptographic Protection good match

SC-13 requires selection and implementation of specific cryptography types, directly stopping use of broken algorithms.

CM-6 Configuration Settings good match

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

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can identify missing salt values through code review or analysis.

SA-15 Development Process, Standards, and Tools partial match

Development standards and tools can mandate salted hashing as part of secure implementation requirements.

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-06 full match
prevents

Secure SDLC practices mandate correct password storage with salts, eliminating this exact weakness.

PR.DS-01 mostly match
prevents

Proper cryptographic hashing for data-at-rest protection directly requires salted hashes for passwords.

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.

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.5.17 Authentication information mostly match
prevents

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

A.8.24 Use of cryptography mostly match
prevents

Mandating approved algorithms, cipher strength and usage standards directly stops the selection of broken or weak cryptographic primitives that attackers can exploit.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect unsalted hashes but does not prevent their introduction.

A.8.9 Configuration management mostly match
prevents

Configuration management processes typically enforce changing defaults during hardening.

A.5.31 Legal, statutory, regulatory and contractual requirements partial match
prevents

The explicit call-out of cryptography-related legal constraints (import/export, key escrow, digital-signature validity) reduces the likelihood that an organization will adopt broken or non-compliant cryptographic algorithms that violate those rules.

A.5.6 Contact with special interest groups partial match
prevents

Access to current specialist guidance and early vulnerability alerts enables timely replacement of broken or risky cryptographic algorithms with stronger alternatives.
