基于Winpcap的网络数据捕获

The Capture of Network Data Based on Winpcap

随着网络技术的不断发展,网站安全问题日益得到关注.文章针对日益突出的网络安全问题,在分析了网络嗅探器的基本工作原理的基础上,描述了Winpcap捕获数据包的程序流程并做了一个网络数据捕获实验.结果表明,这种嗅探器结构简单、捕获数据快,对网络的安全管理具有重要意义.

With the development of network technology, network security is increasing attention. Aiming at safety problems of network and basing on the basic operation principles of network sniffer, this article describes the program of data packet capture on Winpcap and does a network data capture experiment. The result shows that the sniffer is significant to safety management of network, with simple structure and quick capture data.
