The ESXi host must set a timeout to automatically disable idle shell sessions after two minutes.
An XCCDF Rule
Description
If a user forgets to log out of their local or remote ESXi Shell session, the idle connection will remain open indefinitely and increase the likelihood of inappropriate host access via session hijacking. The "ESXiShellInteractiveTimeOut" allows the automatic termination of idle shell sessions. Satisfies: SRG-OS-000163-VMM-000700, SRG-OS-000279-VMM-001010
