城市轨道交通综合监控系统信息安全保护

Information Security Protection of Urban Rail Transit Integrated Supervision Control System

如何应对城市轨道交通综合监控系统面临的信息安全风险,是当前迫切需要解决的问题和挑战。通过分析GB 17859—1999 《计算机信息系统安全保护等级划分准则》中第三级的安全标记保护级的要求,结合综合监控系统软件的应用现状和网络的结构,提出可供相关建设与设计人员参考的信息安全保护建设思路。

The present problems urgently needed to be solved and challengesin information security of urban rail transit ISCS are discussed.By analyzing the requirements of the third security mark protection level in “Classification Criteria for Computer Information System Security Protection”(GB 17859 1999),also combined with the application status of ISCS software system and network structure,suggestions of information security protection construction are put forward for relevant construction and design personnel.
