网络信息安全问题,已经成为制约网络经济进一步发展的重要瓶颈。Web数据挖掘技术是提升网络信息安全防范绩效的关键技术。本文在构建基于Web数据挖掘的网络信息安全防范模型后,还对建立在Web数据挖掘基础上的网络信息安全防范模型运行的基本原理、Web挖掘的数据资源、Web挖掘的技术方法、防范模型的主要应用、模型运行的注意事项等进行了深入分析。 Network information security has become an important bottleneck restricting the further development of the network economy. Web data mining technology is the key technology to improve the performance of network information security. After building the network information security precaution model based on Web data mining, this paper also analyzes the basic principles of the network information security precaution model running on the basis of Web data mining, the data resources of Web mining, the technical methods of Web mining, Main application, the precautions of model operation and so on.
