摘　　要：针对防火墙缺少对内网数据监控的缺陷,本方在对SPI的研究基础之上,设计了一种网络封包过滤和监测系统。通过LSP程序实现网络封包的拦截和过滤,并利用Windows消息实现底层与界面应用程序的数据共享,最终实现对内网数据的监控及过滤。The paper deals with the problem that firewall has the defectd of control packages in LAN. We designed a system which can monitor and foher data packets on local network card as demands. The LSP program can intercept and filter data packets. The analysed result would the shared by GUI program through windows message. And thesystem work well as expected.
