Title
The ESXi host must logout of the console UI after 10 minutes. (Cat II impact)
Discussion
When the Direct console user interface (DCUI) is enabled and logged in it should be automatically logged out if left logged in to avoid unauthorized privilege gains. The DcuiTimeOut defines a window of time after which the DCUI will be logged out.
Check Content
From the vSphere Web Client select the ESXi Host and go to Configure >> System >> Advanced System Settings. Select the UserVars.DcuiTimeOut value and verify it is set to 600 (10 Minutes). or From a PowerCLI command prompt while connected to the ESXi host run the following command: Get-VMHost | Get-AdvancedSetting -Name UserVars.DcuiTimeOut If the UserVars.DcuiTimeOut setting is not set to 600, this is a finding.
