1. A method for protecting a host system from information-security risks posed by a USB removable drive (URD), the method comprising: in a URD having a non-volatile memory in communication with a controller, while there is a local physical connection of the URD to the host system, the controller: identifying, via communication over a network protocol, the URD to the host system as a network drive rather than as a local mass storage device; communicating with the host system, via the network protocol, through a firewall residing in the host system; and decoding data from the host system with the network protocol and writing the data to the non-volatile memory in the URD, wherein the controller of the URD causes the host system to enable firewall security measures of the firewall via communications over the network protocol rather than a mass storage protocol.
