(in versions v1 r3 through v1 r1)
Title
The ESXi host must log out of the console UI after two 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 access by unauthorized persons. The "DcuiTimeOut" setting defines a window of time after which the DCUI will be logged out. Satisfies: SRG-OS-000163-VMM-000700, SRG-OS-000279-VMM-001010
Check Content
From the vSphere Client, select the ESXi host and go to Configure >> System >> Advanced System Settings. Select the "UserVars.DcuiTimeOut" value and verify it is set to "120" (2 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 "120", this is a finding.
