Forescout must be configured to use Coordinated Universal Time (UTC).
An XCCDF Rule
Description
<VulnDiscussion>If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis. Time stamps generated by the application include date and time. Time is commonly expressed in Coordinated Universal Time (UTC), a modern continuation of Greenwich Mean Time (GMT), or local time with an offset from UTC.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Configure Forescout to record time stamps for log records that can be mapped to UTC.
Note: Updating time preferences will force Forescout into maintenance mode and the service must be restarted. Use a scheduled outage for planned maintenance and stop Forescout service prior to adjusting time settings.
