The network element must use two or more NTP servers to synchronize time.


Overview

V-23747 NET0812 SV-28651r2_rule ECSC-1 Low
Description
Without synchronized time, accurately correlating information between devices becomes difficult, if not impossible. If logs cannot be successfully compared between each of the routers, switches, and firewalls, it will be very difficult to determine the exact events that resulted in a network breach incident. NTP provides an efficient and scalable method for network elements to synchronize to an accurate time source.
