| 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. |
