Synchronize system clocks

Requirement#

Critical systems must have synchronized clocks whose configuration is protected and comes from industry-accepted sources.

Description#

Systems must properly record exceptional and security events in protected logs. This allows administrators to find bugs and makes it easier for forensics teams to determine how a system was compromised. However, if clocks are not properly synchronized, it can be very difficult to compare log files from different systems in order to establish the event sequence that led to the security incident.
