Covertly Removing Data From Air-Gapped Networks

In the world of network security, the term air gap refers to a situation in which the computer network is physically separated from other networks, particularly, less secure and public networks such as the internet. Today, air-gapped networks are widely used in military defense systems, critical infrastructure, the financial sector, and other industries.

The air gap isolation is maintained by enforcing strict policies in the organization, which include forbidding external unsecure devices and media from connecting to the network and by using advanced intrusion detection and prevention systems to eliminate intentional and accidental security breaches.
