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

OrtaDüzey 1Otomatikvmware

Açıklama

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.
