The invention provides a safety protection system and method for a train communication network. The system comprises a safety operation management center deployed on a ground side, and a security gateway and a situation awareness host which are deployed in each train marshalling network on a vehicle-mounted side, wherein the ground side is connected with the vehicle-mounted side through a wireless communication network; the situation awareness host is respectively connected with a train communication network control system and a security gateway in a train marshalling network; and the security gateway is connected with a passenger information system and a maintenance interface in a train marshalling network. The train network security protection based on situation awareness has the capabilities of identifying known network threats and sensing unknown threats, integrates active/passive defense, emphasizes overall linkage and collaboration, finds out potential safety hazards possibly existing in the network by extracting whole network attack behavior information, abnormal traffic information, threat intelligence and other information in real time, and improves the security of the network. And comprehensive analysis, research and judgment are carried out on the basis, so that decision support is provided for continuous improvement of train network security.

    本发明提供一种列车通信网络的安全防护系统及方法。系统包括部署在地面侧的安全运营管理中心以及部署在车载侧各列车编组网内的安全网关和态势感知主机,所述地面侧与车载侧通过无线通信网络连接;所述态势感知主机分别与列车编组网内的列车通信网络控制系统、安全网关连接;所述安全网关与列车编组网内的旅客信息系统以及维护接口连接。本发明基于态势感知的列车网络安全防护,具备识别已知的网络威胁并能感知未知威胁的能力,集主/被动防御为一体,强调整体联动协同,通过实时提取全网攻击行为信息、异常流量信息、威胁情报等信息,找到网络中可能存在的安全隐患,并在此基础上综合分析研判,为列车网络安全的持续提升提供决策支撑。
