Research of the intrusion detection system based on data mining

As information the level of the society continues rising, the network has been used as office tools in our daily work, influencing all the aspects of human´s life. As the characteristics of the computer network itself, especially its unique characteristic of openness and shareware, it has brought unprecedented challenges to network security. It has already become the most important problem faced by network workers how a large network can run normally, safely, efficiently and smoothly. On this basis, people began to develop the technology of intrusion detection, which is essentially different from security technologies existed in the past. It is a proactive detection instead of the passive ones of network security technology, and it is a reasonable complement for traditional security technologies. Intrusion detection technology will greatly enhance the network security capabilities.
