Abstract: The cyber attacks against infrastructure such as railways have intensified. In order to ensure the network security of the railway system, it is urgent to further optimize it. This paper briefly combs the structure of the railway network system, considering the development of the current network security defense system, and proposes to apply the latest network security situation awareness technology to the construction of the railway network system, by fully applying the computing power of big data analysis, which build the railway network security situation awareness platform architecture based on big data, and providethe solution for the hidden dangers of the current railway network security defense.

Key words: railway network security, informaiton security, cyber situational awareness, big data, security defense
