摘    要:基于计算机技术的信息技术在电力系统生产、管理中广泛应用的同时,也带来了负面作用。原因是人类的思维特征与好奇心影响信息系统的可靠性、可用性及系统的信任度,进而影响电力系统的安全。文中结合华中电网有限公司信息网络系统的实际情况,在总结了现有安全措施的基础上,提出了一个基于测、控相结合的3层结构容入侵系统模型,论述了相关的原理和功能模块。为了保障容入侵系统本身的安全,提出了利用心跳信息监控各组成部件,并利用表决器诊断技术判断系统是否正常。

关 键 词:电力信息系统  网络安全  容入侵系统

Abstract:With the wide application of the computer technology based information technologies in the production and management of the power system, they also bring many negative effects to the system at the same time. The reason is that human being's thinking character and curiosity influences the reliability, availability and dependence of information systems, furthermore it influences the security of the power system. According to the case of the information network system of China Central Power Grid Limited Company and its existing security measures, this paper presents a tri-level self-protected intrusion tolerant system based on intrusion detection technology and control technology. The relative principles and function modules are discussed. For ensuring the self-security of the intrusion tolerant system, the heartbeat information is used to monitor the system components, and the system's state is judged by using voter technique.
Keywords:electric power information system  network security  intrusion tolerant system
