摘　　要：随着网络安全问题的日益凸显,多地地铁用户提出,希望对信号系统内维护支持子系统(MSS)进行单独组网,并且与信号系统内其他子系统(ATC、CI、ATS、DCS等)接口做好网络安全方面的隔离防护。文章从网络结构设计、边界划分、接口方式等角度,对整体方案进行研究,形成切实可行的网络安全隔离方案,为实际应用提供理论基础。With the increasingly prominent cyber security problems,according to the needs of subway users in many places,it is hoped that the maintenance support subsystem in the signal system can be networked separately,and the interface with other subsystems in the signal system will be isolated and protected in terms of cyber security.This paper studies the overall scheme from the network structure design,boundary division,interface mode and protocol,and forms a practical cyber security isolation scheme,which provides a theoretical basis for practical application.
