Network devices must use at least two NTP servers to synchronize time.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-23747	NET0812	SV-28651r4_rule		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 devices to synchronize to an accurate time source.

Check Text ( C-3581r5_chk )
Review the configuration and verify two NTP servers have been defined. If the device is not configured to use two separate NTP servers, this is a finding.

Fix Text (F-3044r2_fix)
Configure the device to use two separate NTP servers.
