| 摘 要： | 随着铁路信息化的快速发展,铁路多个系统之间实现了互联互通、信息共享和协同工作。然而不同安全等级的业务系统进行通信也带来了一系列严重的网络安全威胁。通过网络物理安全隔离技术.可以将信号集中监测系统(CSM)和列车运行控制系统(CTCS)之间的网络通信协议剥离,有效阻断网络入侵和病毒传播.保障列车运行控制系统的网络安全。

| Abstract: | Over recent years,with the rapid development of railway informatization,interconnection,data sharing and collaborative work have being basically realized among railway systems.However,communication between business systems with different security levels also bring serious threats to network security.By using network physical security isolation technology,the network communication protocol between the Centralized Signaling Monitoring system(CSM)and the China Train Control System(CTCS)can be separated,thus effectively blocking network intrusion behaviors and virus transmission threats and ensuring the network security of the train control system. |
