Description
When additional assurance is required, the system should deny acceptance of a certificate if it cannot verify its revocation status. Otherwise, there is the potential that it is accepting the credentials of an unauthorized system. Allowing the operating system or user to deny certificates with unverified revocation status mitigates the risk associated with the acceptance of such certificates.
