摘要随着信息时代的到来,网络已经成为信息发布和储存的最大平台,由于其“无界性”和连接的“自由性”以及信息的可复制性,使得信息泄露的危险大大增加,因此网络分析与监控问题显得越发重要。本系统通过对流过本地网管的数据包进行捕获和解析,计算相关速度,以监视网络的性能状态和对网络数据流量进行统计,提供有效管理与网络安全控制工具。本文利用在Windows操作系统下比较流行的网络开发包WinPcap, 设计了一种基于winsock的局域网监控系统,基本实现了局域网监控。本系统主要功能包括:捕获并解析网络数据、根据不同协议区分网络活动、生成并可视化显示网络活动相关数据、对常见网络攻击进行报警、对局域网内客户端进行监视。19927

Title MFC Design and Implementation of LAN-based Monitoring Program
Abstract
With the advent of the information age, the network has become the largest information dissemination and storage platforms, since the copy of their "unbounded" and connect the "freedom" as well as information, making the risk of information leakage and therefore greatly increase network analysis and monitoring the problem becomes more important. The local network management system through the data flowing through the packet capture and analysis, the flow rate statistics to monitor the network status and performance data on the network traffic statistics to provide effective management and control of network security tools. In this paper, the use of the Windows operating system more popular web development package WinPcap, designed based on winsock LAN monitoring system, the basic realization of LAN monitoring. The system features include: data capture and resolve network, depending on the agreement to distinguish network activity, generating and visualizing network activity data, common network attacks on the police, on the LAN client monitoring.
