Discussion

Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port that has been left unattended. In addition, quickly terminating an idle session will also free up resources committed by the managed network element. Terminating network connections associated with communications sessions includes, for example, de-allocating associated TCP/IP address/port pairs at the operating system level, or de-allocating networking assignments at the application level if multiple application sessions are using a single, operating system-level network connection. This does not mean that the device terminates all sessions or network access; it only ends the inactive session and releases the resources associated with that session.

Verify the vSphere Web Client sessions terminate after 10 minutes of idle time, requiring the user to log on again to resume using the client. You can view the timeout value by viewing the webclient.properties file.
 
On the system where vCenter is installed, locate the webclient.properties file.
 
Windows: C:\ProgramData\VMware\vCenter Server\cfg\vsphere-client
 
Find the session.timeout = line in the webclient.properties file.
 
If the session timeout is not set to 10 in the webclient.properties file, this is a finding.
