There are cases where, despite blocking a certain category of devices, you may need to allow the use of some specific devices belonging to that category.
In that case you can create a whitelist, that is, a list of devices that will be allowed despite belonging to an unauthorized category.
You can also whitelist blocked devices so that they are not blocked ever again. Click here for more information.
Example: Suppose you have blocked the use of USB devices but you need to allows the use of a specific USB key:
Go to Allowed devices
Click Add.
In the list displayed, select the device that you want to authorize and click OK.
Once you have configured the list of devices to authorize, you can import it or export it into a .txt file. Use the relevant buttons to clear the list or delete a specific device from it.
