The network device must use internal system clocks to generate time stamps for audit records.

Description
In order to determine what is happening within the network infrastructure or to resolve and trace an attack, the network device must support the organization's capability to correlate the audit log data from multiple network devices to acquire a clear understanding of events. In order to correlate auditable events, time stamps are needed on all of the log records. If the internal clock is not used, the system may not be able to provide time stamps for log messages. Additionally, externally generated time stamps may not be accurate. Applications can use the capability of an operating system or purpose-built module for this purpose. (Note that the internal clock is required to be synchronized with authoritative time sources by other requirements.)

Check Text ( C-2165r381680_chk )
Determine if the network device uses internal system clocks to generate time stamps for audit records. This requirement may be verified by demonstration, configuration, or validated test results. If the network device does not use internal system clocks to generate time stamps for audit records, this is a finding.

Fix Text (F-2166r381681_fix)
Configure the network device to use internal system clocks to generate time stamps for audit records.
