Mitigating Controls (NIST 800-53 r5) AI

SC-8 Transmission Confidentiality and Integrity good match

SC-8 directly requires protecting confidentiality of transmitted information, which structurally eliminates cleartext transmission of sensitive data.

PR.DS-02 partial match

blocks

Encryption of data-in-transit directly prevents cleartext transmission while the control also addresses integrity and availability.
