6.10 How to Control Access to USB Devices

You can restrict the access to the USB ports and the connected USB devices:
• USB port key control: Up to two keys are defined for the USB port. Each key can be assigned a validity period
(always, expiration date, weekly period). The USB port and the connected USB device are shown in the SEH
UTN Manager greyed out, i.e. the connection cannot be established. As soon as the key for the USB port is en-
tered in the SEH UTN Manager, the USB port and the connected USB device appear and can be used.
• USB port device assignment: A certain USB device is assigned to a USB port. This is achieved by linking the USB
port and USB device through the vendor ID (short VID) and product ID (short PID) of the USB device. The com-
bination of VID and PID is specific to a certain USB device model which means that only USB devices of this
specific model can be used on the USB port. This way you can assure, that (security) settings cannot be cir-
cumvented by connecting USB devices to other ports.
Power off unused ports to increase security
