The DNS server implementation must, for public key-based authentication, implement a local cache of revocation data to support path discovery and validation.

Description
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. 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.

Check Text ( C-67541r982083_chk )
Verify the DNS server implementation is configured to implement a local cache of revocation data to support path discovery and validation.

If the DNS server implementation is not configured to implement a local cache of revocation data to support path discovery and validation, this is a finding.
Fix Text (F-67449r982084_fix)
Configure the DNS server implementation to implement a local cache of revocation data to support path discovery and validation.
