Isn’t the Air Gap?
Yes, It’s Air Gap.
An air gap, air wall or air gapping[1] 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.[2] The name arises from the technique of creating a network that is physically separated (with a conceptual air gap) from all other networks.
Examples of the types of networks or systems that may be air gapped include:
Military/governmental computer networks/systems;[8]
Financial computer systems, such as stock exchanges;[9]
Industrial control systems, such as SCADA in Oil & Gas fields;[10]
ETC.
