根据国家公共安全行业标准(GA370)2002年5月1日实施的《端设备隔离部件安全技术要求》,文中介绍了一种计算机网络逻辑隔离传输设备的硬件、软件及安全的网络模型连接设计。它既能实现计算机专网与公网间的隔离,又能实现实时的数据交换,是防范黑客侵入、病毒传染和拒绝IP访问的逻辑隔离安全产品。 According to “Safety Requirements for Isolation Components of Terminal Equipment” implemented by the National Public Safety Industry Standard (GA370) on May 1, 2002, the article introduces a hardware, software and secure network model connection design for logic isolated transmission equipment of computer network. It can not only realize the isolation between the private network of computers and the public network, but also realize the real-time data exchange. It is a logical isolated security product that can prevent hacker intrusion, virus infection and reject IP access.
