The Cisco router must record time stamps for audit records that meet a granularity of one second for a minimum degree of precision.

Without sufficient granularity of time stamps, it is not possible to adequately determine the chronological order of records. Time stamps generated by the application include date and time. Granularity of time measurements refers to the degree of synchronization between information system clocks and reference clocks.

Review the Cisco router configuration to verify that it is compliant with this requirement as shown in the example below.

hostname R3 service timestamps log datetime localtime

If the router is not configured to record time stamps that meet a granularity of one second, this is a finding.

Configure the Cisco router to record time stamps that meet a granularity of one second as shown in the example below.

RP/0/0/CPU0:R3(config)#service timestamps log datetime localtime
