办公自动化设备越来越多地进入各级党政机关、企事业单位,被人们广泛地用来处理各种信息,使办公效率大为提高.但是在利用办公自动化设备处理信息时,有些秘密信息在不知不觉中泄漏出去了,因此,我们有必要分析一下办公自动化设备泄密的主要途径:一、计算机的电磁辐射泄密.利用计算机处理信息时,被处理的信息会通过电磁波向空间辐射,其辐射的频率大约在10千赫至600兆赫之间,辐射的主要途径有两个:一是主机辐射,它通过电源线、信号线向外辐射;二是显示器辐射,显示器
Increasingly, office automation equipment has entered the party and government organs, enterprises and institutions at all levels and is widely used by people to process various kinds of information and greatly improve office efficiency. However, when using office automation equipment to process information, some secret information Therefore, we need to analyze the main ways of leakage of office automation equipment: First, the computer electromagnetic radiation leaks. The use of computers to process information, the processed information will be through the electromagnetic radiation to the space, its Radiation frequency of about 10 kHz to 600 MHz between the two main ways of radiation: First, the host radiation, it is through the power cord, the signal line outward radiation; Second, the monitor radiation, the display
