企业网络应用不断增多,为病毒传播创造了条件。黑客技术融合了病毒技术,成为一种新的网络侵入手段,网络入侵者以植入病毒的方式,对有关设备实施控制,将非法指令发送出去,对控制系统配置实施,非授权修改,非法操作程序等,引起了电力系统事故,导致电力网路瘫痪,修改并窃取敏感数据等。主要分析了内外网物理隔离在企业的应用,为企业内外网物理隔离的应用提供借鉴。
Enterprise network applications continue to increase, creating conditions for the spread of the virus. Hackers technology incorporates virus technology and becomes a new means of network intrusion. Network invaders, in the way of implanting viruses, exercise control over the relevant devices and send out illegal commands to control system configurations, unauthorized modifications, and illegal operations Procedures, etc., causing a power system incident, paralyzing the power grid, modifying and stealing sensitive data, and the like. The paper mainly analyzes the application of the physical isolation between inside and outside the network in the enterprise, and provides reference for the application of physical isolation inside and outside the network.
