Nutanix AOS must be configured to synchronize internal information system clocks using redundant authoritative time sources.
An XCCDF Rule
Description
<VulnDiscussion>Determining the correct time a particular application event occurred on a system is critical when conducting forensic analysis and investigating system events. Synchronization of system clocks is needed in order to correctly correlate the timing of events that occur across multiple systems. To meet this requirement, the organization will define an authoritative time source and have each system compare its internal clock at least every 24 hours.
