The network device must be configured to implement certificate revocation checking to support path discovery and validation for public key-based authentication.

Public key cryptography is a valid authentication mechanism for individuals, machines, and devices. For PKI solutions, status information for certification paths includes certificate revocation lists or certificate status protocol responses like OCSP. For PIV cards, certificate validation involves the construction and verification of a certification path to the Common Policy Root trust anchor, which includes certificate policy processing. Implementing a local cache of revocation data to support path discovery and validation also supports system availability in situations where organizations are unable to access revocation information via the network.

Verify the network device is configured to implement certificate revocation checking to support path discovery and validation.

If the network device is not configured to implement certificate revocation checking to support path discovery and validation, this is a finding.

Configure the network device to implement certificate revocation checking to support path discovery and validation using CRL or OCSP.
