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
