The identification system needs to work even on devices that can't be That needs to be answered is: "How can I tell if this device is mine or not?" When constructing a whitelist (or blacklist) of devices, a question Which also specifies the allowed behaviors from approved USB devices. Specify to be allowed on their system and USBGuard enforces those The ideaīehind USBGuard is that there is a set of approved devices that a user can Them or to take certain actions based on USB device events. It is possible to thwart unauthorized or malicious USB port usage byĬontrolling the types of devices that are allowed to connect to Wireless connection that transmits the sensitive information to the The information can either beĬollected by physically retrieving the drive, or it can have its own rogue To be a NIC, hijacks the network and DNS settings, and collects credentialsįrom the all too trusting operating system.

In the absence of software vulnerabilities, it is possible to mount a Spate of vulnerabilities in the USB subsystem that can beĮxploited via specially crafted USB devices is worrying. Problem of malicious USB devices programmed specifically for sophisticated Storage devices on sensitive machines, there is also the Tries to solve: unauthorized use of the USB ports.
Malicious USB attacksīefore we look at USBGuard, let's first take a look at the problem it Which also provides an interface to create access-control policies for theĪuthorization for USB devices already exists, programs like USBGuard make How USB devices can interact with a host system.
