4. Editing the Blacklist and Whitelist
The Port Authentication Utility enables authorized administrators to edit the filtering rules to block (Blacklist) or to
allow (Whitelist) specific USB devices connected to the USB CAC Port on the Secure KVM Switch.
A filtering rule is defined by USB (Base) Class ID, Sub‐Class, Protocol, VID (device Vendor ID), and PID (device
Product ID) of a USB device. For example, a Base Class ID of a Smart Card device is 0Bh.
Base Class
0Bh
By completing the Class ID, Sub‐Class, Protocol, VID and PID field of a filtering rule, the administrator can assign
this filtering rule to the Blacklist or the Whitelist to block or allow a USB device.
When adding the value to Class, Sub‐Class, Protocol, PID or VID field, the last digit "h" can be ignored. For
example, when adding "0Bh" to the Class ID field, just type "0B".
a. Manually adding a filtering rule to the Blacklist / Whitelist
To add a new filtering rule to the Blacklist, click on the "+" icon in the Blacklist command area, and choose
