The electromagnetism leakage of computer is a great threaten to system security. It must implement some ways to prevent the electromagnetism leakage of it. It proposals the ways of information leakage in computer system and analyzes the content of TEMPEST technology and introduces the ways to prevent electromagnetism leakage.The ways are as the following :noise interruption;shielding;red/black line separation ;wave filter;bus line configuration and parts selection;the ways to prevent of electromagnetism leakage for peripheral equipment such as keyboard, disk driver, CRT monitor and printer. And finally, it discusses the 5 ways to develop Tempest technology in China.
