The DNS implementation must produce log records that contain sufficient information to establish what type of events occurred.

Description
Auditing and logging are key components of any security architecture. It is essential for security personnel to know what is being performed on the system, where an event occurred, when an event occurred, and by whom the event was triggered, in order to compile an accurate risk assessment. Logging the actions of specific events provides a means to investigate an attack, recognize resource utilization or capacity thresholds, or to simply identify an improperly configured DNS implementation. Without log records that aid in the establishment of the type of event that occurred, there is no traceability for forensic or analytical purposes.

Check Text ( C-41979r1_chk )
Review the DNS system configuration to determine if it is configured to produce, capture, and store log records which contain sufficient information to establish what type of events have occurred on the system. If the logging function is not configured to produce log records with information regarding the type of event, this is a finding.

Fix Text (F-37883r1_fix)
Configure the DNS server to produce log records with enough information to determine what type of event has occurred on the system. Additionally, configure the audit facility of the DNS system to provide information on the type of events that have occurred.
