摘要
为防范应对铁路综合视频监测系统私接行为,及时定位私接设备,需要着重分析私接设备违法过程,查找合法设备被入侵沦陷原因,从而应对非法接入行为,提高网络运行安全。通过分析铁路内外网络安全事件,总结网络非法设备异常访问及异常路径的特点,提出非法身份私接定位追踪以及网络异常流量追踪安全预警的方法。为铁路综合视频监控系统安全提供新思考。
In order to prevent the illegal connections of the railway integrated video monitoring system and locate the illegal connection equipment in time,it is necessary to focus on analyzing the illegal connection process and fi nd out the reason of the invasion,so as to deal with the illegal access and improve the network operating security.This paper analyzes the network security incidents inside and outside the railway,summarizes the characteristics of abnormal access and abnormal paths of illegal network equipment,and proposes a method of illegal connection location tracking,network abnormal traffic tracking and security early-warning.It provides a new thought for the security of railway integrated video monitoring system.
