Solutions are needed to replace the archaic air-gapping of computers used to isolate and protect sensitive defense information, the U.S. Government has decided. Air-gapping, used often now, is the practice of physically isolating data-storing computers from other systems, computers, and networks. It theoretically can’t be compromised because there is nothing between the machines — there are no links into the machines; they’re removed.
However, many say air-gapping is no longer practical, as the cloud and internet takes a hold of massive swaths of data and communications.
