The Juniper router must be configured to record time stamps for log records that can be mapped to Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT).

If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis.

Time stamps generated by the application include date and time. Time is commonly expressed in Coordinated Universal Time (UTC), a modern continuation of Greenwich Mean Time (GMT), or local time with an offset from UTC.

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

system { time-zone UTC;

Note: UTC is the default; hence, the command set time-zone may not be seen in the configuration. This can be verified using the show system uptime command.

If the router is not configured record time stamps for log records that can be mapped to UTC or GMT, this is a finding.

[edit system] set time-zone UTC
