An air gap (air grp), or disconnected network, is a network security measure employed on one or more computers to ensure that a secure computer network is physically isolated from unsecured networks, such as the public Internet or an unsecured local area network. It means that a computer or network has no network interface controllers connected to other networks, with a physical or conceptual gap, analogous to the air gap used in plumbing to maintain water quality.
