Mitigating Controls (NIST 800-53 r5) AI
Requiring specific approved cryptography for protection directly mandates use of strong PRNGs instead of weak ones.
Key establishment and management requirements force use of approved RNG sources with adequate entropy when generating keys.
Authenticator management requires secure generation, distribution, and storage of passwords, directly enforcing computationally expensive hashing schemes.
Security engineering principles can include selection of strong entropy sources during design.
Protection of information at rest requires cryptographic safeguards on stored password hashes, reducing exposure to offline cracking.
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.
Proper password hashing is a direct instance of using cryptographic hashes to protect data-at-rest.
Secure SDLC practices explicitly include vetted RNG and entropy sources, directly preventing this weakness while covering many other development concerns.
Password-strength policies implicitly require sufficient entropy, but the control addresses authentication rather than algorithmic randomness.
Cryptographic protection of data-in-transit depends on adequate entropy; the weakness directly undermines the control's effectiveness.
