Disabling Devices
In general, it is a good practice to disable any unused devices in your system. This may include USB ports, CD/DVD drives or communication ports.
If it is not possible to disable a device, it is good to disable the autorun functionality of the device. To prevent the automatic start of malicious code contained in a removable device, the autorun functionality must be disabled. For more information, see the Product’s Installation Procedure.
