Discussion

Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when conducting forensic analysis and investigating system events. Sources outside the configured acceptable allowance (drift) may be inaccurate. Synchronizing internal information system clocks provides uniformity of time stamps for information systems with multiple system clocks and systems connected over a network. Organizations must consider endpoints that may not have regular access to the authoritative time server (e.g., mobile, teleworking, and tactical endpoints).

Confirm Nutanix AOS is running the NTP service.

# sudo ps -ef | grep ntp
ntp       7447     1  0 Aug17 ?        00:00:05 /usr/sbin/ntpd -u ntp:ntp -g

If the NTP service is not running, this is a finding.

Next Check the ntp.conf file for the "maxpoll" option setting.

$ sudo grep maxpoll /etc/ntp.conf
server #.#.#.# maxpoll 10

If the option is set to "17" or is not set, this is a finding.
