10 USB Security
PCoIP Technology provides granular security
over USB devices. This allows authorizing or
deauthorizing (blocking) USB devices.
USB security is applied in the following priority
order:
1. Unauthorized Vendor ID/Product ID (highest
priority)
2. Authorized Vendor ID/Product ID
3. Unauthorized Device Class/Sub Class/
Protocol
4. Authorized Device Class/Sub
Class/Protocol (lowest priority)
The sections below show three USB security
examples:
• Authorizing USB device by Class
• Authorizing USB device by Vendor ID and
Product ID
• Deauthorizing (Blocking) a USB device by
Class
Example: Authorizing USB Device by
