摘要
现今网络技术的发展和网络应用的普及,越来越多的信息资源放在了互联网上,来让人们浏览下载等。因此网络的安全性和可靠性显得越发重要。嗅探器Sniffer是一种利用计算机网络接口件事网络数据运行、截获网络数据的工具,可用于网络管理、网络协议分析以及网络安全等众多方面。在网络攻防技术中,嗅探器是最为基础的一种技术。从供给的角度,黑客可以利用嗅探器程序非法获取网络中传输的大量敏感信息,如账号和口令等,对网络安全极具威胁;从防守的角度,嗅探技术是基于网络入侵检测系统的最底层环节,是整个系统的数据来源。本次课程设计通过分析网络上常用的嗅探器,在了解其功能和原理的基础上,以Visual C++ 为开发平台设计并实现一款基于Windows环境下的网络嗅探器。按照网络工程的思想进行设计、实现和测试。

Abstract
Along with the development work technology and popularization of work applications, more and more of the information resources on the , the safety and reliability of work is ing more and more important. Sniffer is a use work interface work data operation, intercept work data tools, can be used work management, network protocol analysis work security etc. In work attack and defense technology, sniffer is the most basic kind of technology. From the point of view of supply, hackers can use sniffer program for the transmission of work of sensitive information, such as account and password, etc, to work security threats; From the point of view of defense, sniffer technique is based on work intrusion detection system of the bottom link is the source of data for the whole system. This course design through the analysis on work monly used a sniffer in understanding the functions and principles, and on the basis of Visual C++ for development platform to design and implement a Windows environment based on work sniffer. According to work project design, implementation and thoughts on the test. For the sniffer the general framework design, divided five parts, respectively is bottom data cache, and data access layer, data capture, protocol analysis and data filtering and the top graphical user interface. To realize the interface, the work protocol IP address, destination IP address and port number display of the information such as the program, so that it can be prehe
