摘要: 为提升铁路企业网络安全风险感知水平,提高风险防控能力,保障信息系统安全稳定,通过综合分析铁路信息系统中存在的风险和不安全因素,结合信息系统网络安全等级保护相关文件要求,提出一种包含贯彻执行国家、国铁集团网络安全制度、安全相关经费保障、网络和主机安全、系统运行安全4个层面的风险评价指标;引入层次分析法(AHP)确定各项评价指标的权重,进而提出一种定量与定性相结合的评价指标体系。结果表明:该评价指标体系能够较为客观、准确、便捷的评价铁路信息系统网络安全风险,进而提升信息系统网络安全防护水平。

Abstract: In order to improve the level of railway enterprise network safety risk identification and strengthen risk control ability to ensure the safety and stability of railway information system. Through comprehensive analysis of railway information system and risk of unsafe factors, combined with the network information system safety levels to protect related documents, put forward a kind of to carry out national, China railway group network safety system, for ensuring adequate funding for safety, network and host safety, system running safety of four levels of risk evaluation indexes. AHP was introduced to determine weight of each evaluation index, and then a quantitative and qualitative evaluation index system was proposed.The results show that evaluation index system can objectively, accurately and conveniently evaluate network safety risk of railway information system, and then improve network safety protection level of information system.

Key words: analytic hierarchy process(AHP), information system, risk assessment, index system, network safety
