An Approach to Secure Air-gap system from Intentional Radio Transmission

-. Intentional Radio Transmission from video signal of system is one of such attack. In this attack transmitter code executing on air-gap system will generate Radio Signals at specific frequency, which will be received by nearby radio receiver device. In this paper, we tested this attack scenario and propose a technique to secure from such transmissions. Air-gap approach is widely used for critical information systems. This approach gives us illusion that our data is secure from any potential attacks and data leakage. But, there are few covert channels which can be used to attack these systems. - See moreat: .
