Abstract: To solve the problem of insufficient active defense capability of railway network security, relieve the pressure of long-term passive protection, and strengthen the ability of active security protection, a solution to attack and defense range platform for railway network is presented to tackle those prominent problems of network security in combination with the current situation of railway network security. By integrating existing resources, this platform can simulate actual environment of railway network and provide a wide range of services including simulation of business traffic flow, network offensive and defensive countermeasures drill, network security reinforcement test, personnel training and education, conducive to improve defense capability of railway network security and to enhance the level of railway network security protection.
