摘　　要：铁路通信数据网、传输网等网络安全等保建设陆续开展,根据铁路通信网络安全防护“整合、集中、防护”的策略,提出在各通信网管网络安全边界利用虚拟防火墙技术共享一套网络安全等保系统的思路,以实现各系统业务隔离、管理控制隔离、共享设备资源的目的,满足各通信系统网管网络安全的需求。Against the background of the development of network security technologies such as railway communication data network and transmission network,and in accordance with the strategy of"integration,centralization and protection"for security protection in railway communication networks,this paper puts forward the concept of using the virtual fi rewall technology to share one network security protection system at the network security boundary of various communication network management systems.The proposed concept aims to achieve the purposes of service isolation,management and control isolation,and equipment resource sharing among various systems,so as to meet the network security needs of various network management systems for communication systems.
