IDS在铁路计算机网络中的应用与研究

THE APPLICATION AND STUDY OF IDS IN THE RAILWAY INFORMATION NETWORK

我国铁路计算机网络实现了信息资源的快速交互与共享利用,但网络病毒、篡改信息和网络阻塞等危险因素也对其构成了越来越大的威胁,给铁路运输安全埋下了隐患。构造高效的安全防卫屏障,保障铁路计算机网络的安全迫在眉睫。本文将主成分分析方法和BP网络结合起来实现入侵检测,运用到铁路计算机网络安全防护中具有较好的现实意义,不仅能检测出系统中威胁到系统安全的行为,还能有效地弥补防火墙的先天不足。

Computer Engineering of Railway achieved rapid interaction and sharing the information,but the network viruses,tampering with information and network congestion,and so risk factors also pose a growing threat to the railway transport safety conceals potential problems. And efficient security and defense barrier constructed to protect the safety of the railway computer network imminent. This will be the principal component analysis method and the BP network work together to achieve intrusion detection,applied to computer network security protection of the railway has a good practical significance,not only can detect the system behavior of a threat to system security,but also effective to compensate for the firewall congenitally deficient.
