Host must deny shell access for the dcui account
Description
The dcui account, utilized for process isolation for the Direct Console User Interface (DCUI), possesses shell access which, when deactivated, minimizes the attack surface. This action is a proactive measure to enhance system security. The audit runs esxcli system account list and requires Shell Access false for dcui. Runs in the ESXi Shell (busybox sh) as root.
