Mitigating Controls (NIST 800-53 r5) AI

SC-13 Cryptographic Protection good match

Cryptographic protection mandates approved algorithms and key management that preclude weak encoding schemes for sensitive data such as passwords.

IA-5 Authenticator Management partial match

Authenticator management requires secure generation, storage, and distribution of passwords rather than trivial encoding.

SC-12 Cryptographic Key Establishment and Management partial match

SC-12 governs cryptographic key establishment and management, which can enforce sufficient key sizes and thereby reduce inadequate encryption strength.

PR.DS-01 mostly match
prevents

Proper cryptographic hashing for data-at-rest directly prevents trivial password encoding while the control addresses broader data protection needs.

PR.DS-02 mostly match
prevents

Strong encryption is required to protect confidentiality of data-in-transit.

PR.PS-01 partial match
prevents

Hardened baselines can enforce minimum cryptographic algorithm and key-length settings.

A.8.24 Use of cryptography mostly match
prevents

Requires appropriate use of cryptography, indirectly discouraging weak encoding schemes.

A.5.17 Authentication information partial match
degrades

Requires secure handling and protection of authentication information, directly addressing weak password encoding.

A.8.28 Secure coding partial match
prevents

Enforces secure coding practices that would reject trivial password encoding.

A.8.5 Secure authentication partial match
degrades

Mandates secure authentication mechanisms, which precludes trivial encoding of passwords.
