Mitigating Controls (NIST 800-53 r5) AI

PKI certificate issuance and acquisition under an approved policy establishes the trusted roots and processes needed for correct validation.

Protecting session authenticity depends on cryptographic mechanisms whose trust depends on correct certificate validation.

Requiring confidentiality and integrity protection of transmitted data drives use of properly validated certificates in protocols such as TLS.
