The Riverbed NetProfiler must be configured to 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.

Go to Administration >> General Settings.

Under "Time Configuration", verify that redundant NTP servers have been configured.

If NTP is not configured, this is a finding.

Go to Administration >> General Settings.

Under "Time Configuration", enable and configure redundant NTP servers.
