The ESXi Host Client must be configured with a session timeout.
An XCCDF Rule
Description
The ESXi Host Client is the UI served up by the host itself, outside of vCenter. It is accessed by browsing to "https://<ESX FQDN>/ui". ESXi is not usually administered via this interface for long periods, and all users will be highly privileged. Implementing a mandatory session idle limit will ensure that orphaned, forgotten, or ignored sessions will be closed promptly.
