网络信息监控系统的设计与实现

Design and Realization of Network Information Monitoring System

针对网络中出现的病毒、木马、黑客攻击、非法言论的传播等新的威胁,在校园网中设计并实现了一个基于B/S架构的网络信息监控系统,具备了对内部网络信息管理的初步功能。系统的建立采用基于WinPcap的网络编程技术,使用WinPcap在C++下的封装类SharpPcap,采用C++语言来设计和开发。该系统分为数据包捕获、分析与保存、查询与统计、管理4个部分。系统运行结果表明,校园网中存在大量垃圾流量和病毒流量,确实需要一套局域网内的网络信息监控系统。

For the new threats of virus,Trojans,hacker attacks,illegal speech,etc.in the network,the network information monitoring system based on B/S framework was designed and realized in campus network,which had the preliminary function to manage the internal network information.The system which based on WinPcap network programming techniques was designed and developed by using WinPcap in C＋＋ under the package class SharpPcap and C＋＋ language.The whole system was divided into four parts： data packet capture,analysis and preservation,search and statistic and management.System operation results indicated that there were large amounts of rubbish flow and virus flow in campus net.It really needed a set of network information monitoring system within the local area network.
