Description: Vc ++ programming realizes network sniffer
Personnel engaged in network security technology and quite a number of would-be hackers use of existing hacker attack (those not according to the need to write your own code) is certainly not on a network sniffer (sniffer) unfamiliar, a network sniffer in both network security and hacker attacks in play an important role. By using the network sniffer, the network card can be set in a hybrid mode, and the capture and analysis of the packets transmitted on the network can be realized. This analysis can be used for network security analysis, but the use of hackers can also provide valuable information for further attacks. It can be seen that the sniffer is a double-edged sword. Although after a network sniffer technology by hackers use would be a threat to network security, but the harm of sniffer itself is not very big, is mainly used to provide network information for other malware, the real attack is mainly accomplished by other black soft. In the aspect of network security, network sniffing means can effectively detect packet information transmitted over the network, and the analysis and utilization of these information can help network security maintenance. Weighing the advantages and disadvantages, it is necessary to introduce the realization principle of network sniffer.
