The DNS server implementation must compare the internal system clocks on an organization-defined frequency with organization-defined authoritative time source.

Synchronization of internal system clocks with an authoritative source provides uniformity of time stamps for systems with multiple system clocks and systems connected over a network.

Verify the DNS server implementation is configured to compare the internal system clocks on an organization-defined frequency with organization-defined authoritative time source.

If the DNS server implementation is not configured to compare the internal system clocks on an organization-defined frequency with organization-defined authoritative time source, this is a finding.

Configure the DNS server implementation to compare the internal system clocks on an organization-defined frequency with organization-defined authoritative time source.
