电力系统计算机网络信息安全的防护

随着电力信息系统发展越来越快,信息系统的安全日益重要。简要介绍了电力系统加强计算机网络信息安全的必要性,以及3种安全运行模式的性能,论述了数据库的安全性设计原则并提出了电力二次系统安全防护策略与方案。以宝山供电分公司的网络系统运行为例,分析了网络信息系统存在的问题以及系统安全改进的方向。

Security Protection of the Computer Network Information in Power System

With the faster development of power information system, its security is increasingly more important. The necessity to enhance the security of computer network information system is briefly presented together with the performances of three kinds of safe operation modes. The security design principle of data- base, security protection strategy and schemes for secondary system of power system are explored. Taking the operation of network system in Baoshan Power Supply Company as example, the existed problems of network information system and their improvement direction are analyzed.
