计算机网络的安全防范与监控

随着铁路信息化水平的不断提高,计算机网络在铁路建设的发展进程中扮演了越来越重要的角色.由于信息化对网络的依赖性越来越强,网络的安全性问题日渐突显.针对计算机网络的安全现状,结合实际的工程项目和改造项目,以系统化和层次化的控制理论为指导思想,从网络防御和监控的角度描述建立一个实用的网络安全架构,确保网络信息的安全.

Security precaution and supervise to computer network

With the constant improvement of railway informatization, computer network played more and more importantrole. The more relayed on the network, the more important to the network security. According to the current situation ofcomputer network, it was found a practical security frame of network, based on precaution and supervise of computernetwork. With practical project and update project, using the controlling theory of the system and level, security for theinformation of network was guaranteed.
