Abstract: In view of the need to further enhance the railway's own network security protection ability and improve the training of railway network security talents, combined with various technologies such as software defined network, role-based access control and automatic multi-dimensional testing, this paper designed an immersive railway cyberspace shooting range scheme, which had the functions of safety training, martial arts competition, shooting range drill and so on. It provided a multi-level and highly coupled platform for railway network security practitioners to study and train. Popularization and application in the railway industry would effectively improve the network security technology level of railway practitioners and form the endogenous network security defense ability of railway.
