VCWN-06-000002 - The system must not automatically refresh client sessions.


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. Automatic client session refreshes keep unused sessions online, blocking session timeouts.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.


You can change the refresh rate value by editing the file.

On the system where vCenter is installed locate the file.

Windows: C:\ProgramData\VMware\vCenterServer\cfg\vsphere-client
Appliance: /etc/vmware/vsphere-client/

Edit the file to include the line 'refresh.rate = -1' where -1 indicates sessions are not automatically refreshed. Uncomment the line if necessary.

After editing the file the vSphere Web Client service must be restarted.
