The DNS server implementation must protect nonlocal maintenance sessions by separating the maintenance session from other network sessions with the system by logically separated communications paths. (Cat II impact)

Discussion

Nonlocal maintenance and diagnostic activities are conducted by individuals who communicate through either an external or internal network. Communications paths can be logically separated using encryption.

Check Content

Verify the DNS server implementation is configured to protect nonlocal maintenance sessions by separating the maintenance session from other network sessions with the system by logically separated communications paths. If the DNS server implementation is not configured to protect nonlocal maintenance sessions by separating the maintenance session from other network sessions with the system by logically separated communications paths, this is a finding.
