The DNS implementation must produce a system-wide audit trail composed of log records in a standardized format.

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 system. The audited events must be in a standardized format in order to conduct accurate forensic analysis of the events.

Check Text ( C-42019r1_chk )
Review the DNS implementation to determine if it is configured to send all log data to either the system logging facility (e.g., UNIX syslog or Windows Application Event Log) or an alternative logging facility with security configuration equivalent to, or more restrictive than the system logging facility. The log data must be in a standardized format. If audit logs are not centralized in a standardized format, this is a finding.
