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