Mitigating Controls (NIST 800-53 r5) AI

SC-8 Transmission Confidentiality and Integrity good match

SC-8 requires confidentiality protection for transmitted data, directly stopping credentials from traveling in plaintext.

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.DS-02 full match
prevents

Encryption of data-in-transit directly prevents exposure of credentials during login.

PR.AA-04 mostly match
prevents

Protecting identity assertions in transit covers credential transport but is narrower than the full control scope.

A.8.24 Use of cryptography mostly match
prevents

Requires use of cryptography, directly enabling encryption of credentials in transit.

A.5.14 Information transfer partial match
prevents

Requires secure information transfer, which can include protecting credentials in transit.

A.5.17 Authentication information partial match
degrades
