摘  要

本文主要阐述了目前网络安全的现状、缺陷、面临的威胁,提出了相应的防范措施,并介绍了网络的常用协议。然后又介绍了WINSOCK技术和监听原理,并对最广泛的监听工具sniffer做了简单的概述。基于当前网络很多威胁都是来自与自己电脑的漏洞与自己不能够清楚的察觉到自己电脑是否正在被侵犯,虽然防火墙可以提供帮助,但它不能对低层的东西显示给大家。本文主要研究的是对局域网的数据包监听并分析,采用WINSOCK技术实现的。在此工具中主要有监听和IP数据包分析2大主要功能,并能通过窗体清楚的显示出来。它使人们可以每时每刻观察到进入自己电脑的数据包,并能够观察到进行数据交流时对方的IP地址和所开放的端口号,及时对信息明朗化,预防黑客端口的监听。

Abstract

This text has explained the current situation , defect , threat faced of the online security at present mainly, have put forward the corresponding precautionary measures, has introduced the daily agreement of the network. Recommend winsock technology and monitor principle , monitor to a most extensive one tool sniffer make the simple summary。On the basis of network a lot of threat to come from with one's own loophole and oneself of computer can not clear perceiving whether one's own computer is being infringed at present, though the fire wall can offer help , it can't show to the thing of the lower to everybody . Main research of this text is wrapping up and monitoring and analysing about the data of the lan, adopt wincock technology to realize.Monitor and wrap up and analyse 2 great main functions with ip data mainly in tool once, and can come out through the display that the window body is clear . Its people can observe all the time the data which enter one's own computer are chartered , and can observe the other side's ip address and end slogans opened while exchanging the data , clear to information in time, prevent the monitoring of black ports.
