"An air gap, air wall or air gapping 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. The air gap may not be completely literal, as
|
|
|
|
networks employing the use of dedicated cryptographic devices that can
|
|
|
|
tunnel packets over untrusted networks while avoiding packet rate or size
|
|
|
|
variation can be considered air gapped, as there is no ability for computers
|
|
|
|
on opposite sides of the gap to communicate."
