摘要
国家基础设施城市轨道交通的安全运行对国家安全、社会稳定具有重大的影响。近几年来安全事件的频繁发生,使得城市轨道交通安全问题备受关注,其信息系统所面临的安全问题也日益突现。依据城市轨道交通的运行现状,结合信号系统的特性,对国家基础设施城市轨道交通信号系统的脆弱性、安全威胁和风险点进行了分析,最后提出了相应的对策建议。
The safe operation of national infrastructure urban rail transit has great influence on national security and social stability. With the frequent occurrence of security incidents in recent years, the safety problems of urban rail transit have attracted much attention, and the security problems faced by its information system have become increasingly apparent. According to the present situation of urban rail transit and the characteritics of signal system, the vulnerability,security threat and risk point of national infrastructure urban rail transit are analyzed, and the corresponding countermeasures and suggestions are proposed.
