USBGuard: authorization for USB

USBGuard is a security framework for the authorization of USB devices that can be plugged into a Linux system. For users who want to protect a system from malicious USB devices or unauthorized use of USB ports on a machine, this program gives a number of fine-grained policy options for specifying how USB devices can interact with a host system. It is a tool similar to usbauth, which also provides an interface to create access-control policies for the USB ports. Although kernel authorization for USB devices already exists, programs like USBGuard make it easy to craft policies using those mechanisms.
