Securing Air-Gapped Systems

A security measure which involves isolation of a computer or a network in order to prevent it from establishing an external connection, such a security measure is called air gapping. If we are able to physically segregate a computer in such a way that it becomes incapable of connecting wirelessly or physically with other computers network or devices, then that computer is an example of an air-gapped computer. Since air-gapped computers are neither connected to the Internet nor other networks that are connected to the Internet, this makes hacking such computers quite difficult. If we are able to cut off any connection to the computer, then only we can guarantee that no third party would be able to access the client. The object of this paper is to verify the feasibility of air gapping.
