浅谈铁路货运信息系统的网络安全

针对铁路货运管理信息系统网络基础设施所存在的网络结构平面化，不能抵御强大的攻击、广域网没考虑分层，基本处于无度的逻辑连接状态、网络设备及链路的容错性和可控性差等安全问题，提出了IP地址的合理规划、层次化的网络结构、协同的访问控制策略、网络系统自身的健壮性等IP网络及基础设施的安全技术。

Network security of railway freight transportation information system

In this paper, some security technologies involving the network and infrastructure such as the ideal layout of IP address, the arrangement of network structure, cooperative access control strategy, the haleness of network system are proposed aiming to resolve issues of network infrastructure of the railway transportation management system such as only existing one layer in the network infrastructure, no resistance to the heavily attack, no consideration of layered WAIS's structure, being randomly logic joint state, the bad fault tolerant and control properties.
