“TEMPEST” is the government codeword for the unintentional radiation leakage of information from electronic equipment. Theoretically, such radiation leakage can occur from almost any equipment. In IT systems, the most likely leakage is from the Visual Display Unit (VDU) drive circuitry. This effect can be unintentionally enhanced by the video cable which connects the computer base unit to the VDU itself. The nature of the threat as far as sensitive information is concerned is that the picture on the VDU screen is broadcast and is picked up on a suitably modified television some distance away from the IT system in question.
