It was right around that time that scientists began to turn their attention to another project: trying to access these protected networks remotely, through the air, by reading activity via electromagnetic field distortions and inserting code via radio frequencies. Accessing these networks — networks that don’t have wireless routers and aren’t connected to the Internet — became something of a holy grail, dubbed “jumping the gap.”
The science has progressed significantly, and now the Army is looking at demonstrating technology that can be deployed on aircraft and ground vehicles that can wage this kind of cyber warfare.
