7.5. Enabling Revocation Checking

Revocation checking means that a Certificate System subsystem verifies that a certificate is both valid and not revoked when an agent or administrator attempts to access the instance's secure interfaces. This leverages a local OCSP service (either a CA's internal OCSP service or a separate OCSP responder) to check the revocation status of the certificate.
