Virtual machines must be configured to lock when the last console connection is closed

中レベル 1自動vmware

説明

Configuring virtual machines to lock upon closing the last console connection enhances security by mitigating the risk of unauthorized access via open console sessions. This configuration is particularly useful in environments where multiple users have access to the console. Expected: tools.guest.desktop.autolock = "TRUE". The audit parses every .vmx file under /vmfs/volumes/ on the host and lists the VMs that do not comply; it passes when none are found (or no VMs exist). Runs in the ESXi Shell (busybox sh) as root.

The following PowerCLI command may be used: If the audit returns blank or the value is not yet set Get-VM -Name $VM | New-AdvancedSetting -Name tools.guest.desktop.autolock $True otherwise use Get-VM | get-AdvancedSetting -Name tools.guest.desktop.autolock | set- advancedsetting -Value $True
