电力信息系统安全可靠性研究

介绍了电力信息系统安全体系现状,给出安全体系规划设计和安全防护措施。阐述了电力信息系统安全体系中存在的威胁。从安全体系设计方法要求和网络安全策略2个方面提出电力信息系统安全策略,对于不同安全等级构成的系统应进行安全分区,不同安全等级的分区间应部署相应的物理隔离设备。电力信息系统安全可靠性研究对保证系统的安全可靠运行具有重大意义。

Study on the Security and Reliability of Power Information System

The paper introduces the current status of power information security system,presents planning and design of the security system as well as security protection measures,and describes the menace existed in the power information security system.Power security strategy is brought out from the two aspects of security system design method requirements and network security strategy.Security zoning should be employed in systems composed of different security levels and corresponding physical isolation equipments should be disposed among zones with different security levels.There is great significance of study on security and reliability of the power information system to the secure and reliable system operation.
