英文摘要：

Network information security has become an important bottleneck in restricting the further development of network economy. Web mining technologies are the key technologies to improve the performance of network information security defence. After constructing the network information security defence model based on Web mining, this article gives a thorough analysis on the network information security defence model based on Web mining, including the basic operational principle of the model, the data resources of Web mining, the technologies and methods of Web mining, the main applications of the model and the points for attention of the model.
