Some system administrators would like to prevent hardware damage to the computers the operator share access to and disable the Power Off command which is a hard shutdown that can cause data loss.
By default, all System Commands are enabled, however, you get the option to customize their availability.
For example, if you would like to allow only restart commands to be sent, just uncheck all boxes except for "Restart".
Login command is only supported by Microsoft Windows Vista or Microsoft Windows Server 2008 (or newer) and if Secure Attention Sequence (Control + Alt + Delete) is enforced by Group Policy then the Microsoft Windows 7 or Microsoft Windows Server 2008R2 (or newer) is required.
The allowed system commands can be configured in the "Server Admin > Endpoint Policies > System > General" section of the Web App.
You can also configure these settings on the VSAX Agent itself. However, the Web App Policy settings (if applied to the same machine) will always take precedence over the individual agent settings.
Also, Policies are naturally more convenient for applying such monitoring rules, as they can be applied to multiple machines simultaneously.
To configure these settings on the Agent, go to the "System > General" tab.
