10 USB Security

PCoIP Technology provides granular security

control to authorize and unauthorize USB

devices.

Note: The USB security is applied in the

following priority order (Unauthorized Vendor

ID/Product ID has highest priority):

1. Unauthorized Vendor ID/Product ID

2. Authorized Vendor ID/Product ID

3. Unauthorized Device Class/Sub

Class/Protocol

4. Authorized Device Class/Sub Class/Protocol

Following are three USB

authorization/unauthorization examples:

• Authorize specific class of printers

• Authorize specific vendor/product ID

combination

• Unauthorize mass storage devices

Authorizing USB by Class

1. In the Authorization section, select Add new

button.

this example, only printers supporting a

specific protocol are authorized. Select

Printer.

desired IEEE 1284.4 compatible bidirectional

protocol is chosen, and the USB permissions

entry is complete.
