摘　　要：In the information age, computer network technology has made great progress. The Internet has become an indispensable part of the lives of hundreds of millions of Internet users. The problem of network security has evolved from "basically not a problem" to a big problem. Modern train communication network continues to expand its openness, interconnectivity and sharing. Although it can enhance the close integration with people's lives, it brings unprecedented threat to the real-time and reliable transmission of train data. Ensuring the safety of train network has become the top priority of modern train communication network. The essence of network security is to ensure that only authorized users can access the mobile and static data information in the network, thus ensuring the reliability and authenticity of the network system and the confidentiality and integrity of the data information. For various security threats in the current train Ethernet network, the commonly used train network security technologies mainly include digital encryption technology, virus protection, network authentication and authorization, firewall, network intrusion detection, etc.
