The Palo Alto Networks security platform must record time stamps for audit 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 and must be expressed in Coordinated Universal Time (UTC), also known as Zulu time, a modern continuation of Greenwich Mean Time (GMT).

Go to Device >> Setup >> Management In the "General Settings" window, if the time zone is not set to "GMT" or "UTC", this is a finding.

Go to Device >> Setup >> Management In the "General Settings" window, select the "Edit" icon (the gear symbol in the upper-right corner of the pane). In the "General Settings" window, in the "Time Zone" field, select "GMT" or "UTC" from the list of time zones. Select "OK". Commit changes by selecting "Commit" in the upper-right corner of the screen. Select "OK" when the confirmation dialog appears.
