USB blocking is a simple data leakage prevention technique adopted to prevent malicious removable storage devices from stealing your data via USB ports. Blocking USB devices helps secure your data by preventing it from being copied into unauthorized removable devices.
Connections of all external devices takes place through USB ports. Identifying the intent of such devices is hard since malware exist on the firmware of the device.
