电力信息系统安全体系设计方法综述

A SURVEY TO DESIGN METHOD OF SECURITY ARCHITECTURE FOR POWER INFORMATION SYSTEMS

电力信息系统是由众多复杂异构的子系统组成的超大规模、广域分布和分级递阶的大系统,它的安全是多因素和多维的。为此,需要一种系统化和结构化的设计方法以及相应的辅助工具设计电力信息系统的安全体系。文章阐述了电力信息系统安全体系设计方法的研究现状,并从安全需求的不确定性和系统的动态、分布特征等方面深入分析了信息系统安全体系设计中可能存在的问题,最后明确提出了对电力信息系统安全体系设计方法的要求。

Power information system is a large-scale, distributed, wide-areal, hierarchical system with numerous heterogeneous sub-systems, which security is multifactorial and multidimensional. So to design the security architecture of power information system, a systematic and structural design method and corresponding computer-aided tools are necessary. Here, the importance and present study situation of the design method for security architecture of power information system is expounded, the problems which may exist in the design of security architecture are analyzed in depth with respect to the uncertainty of security requirements and the dynamic and distributed characteristics of information systems. Finally, the requirements to the design method of the security architecture of power information system are put forward.
