摘要
移动互联网监控仪由嵌入式硬件和监控软件两部分组成,嵌入式硬件由CPU、Flash存储器、以太网接口卡、无线网卡组成,监控软件由基于Linux内核的主程序和分析程序组成,主程序捕捉经过网络终端传输的数据包,分析程序把过滤所得的数据包发送给后台服务器存储。在移动互联网中进行数据链路层监控,用户自定义需要监控的关键字,对数据进行关键字和主题领域的列表进行字符匹配,对敏感信息数据包或者不和谐内容的数据包进行监控并存储。
Designs and implements mobile Internet security monitor based on embedded Linux, by listening on the network packets, containing a set of sensitive information packet uploaded to the storage server for evidence. The embedded development board used for network monitor client, based on system kernel Linux 2.6.30, CPU S3C2440（400MHz）, with Ethernet interface, the equipment has low cost, small volume and light weight, convenient carrying and installation, especially suitable for public sites and small office. The monitor does not affect the speed of Internet access, and the energy consumption is low, more energy saving and environmental protection.
