Study On Network Users' Behaviors Analysis And Its Application

With the quick development of the Internet, It is a fact that the expansion network services including amusement, electron service and electronic commerce substitute for the traditional ones including information search and network communication, etc.. On one hand, the question of the security is more and more outstanding, and becomes a basic guarantee of the computer and network's benign growth; On the other hand, the profitable websites such as the business websites,etc, need to offer more satisfactory service through analysing users' behaviors and hobbies in order to obtain maximum profits. And these are correlated extremely with improving efficiency and individualized degree of websites service. As to nonprofit website such as govemment,scientific research institution, need to analyse users for scientific decision-making too. For these reasons, classification,analysis and research on network users' behaviors demand to be mentioned urgently.The work reads as follows: setting up the concept of network users' behavior and categorised system, then discussing the classification of users based on network users' behavior; analyzing the information source of network behavior analytical system, considering mostly two respects of efficiency and accuracy of behavior information; probing into the demand,step and system frame for establishing network user's behavior analytical system, and discussing some key technology in course of the system implementation; Then putting forward several kinds of common application modes or thought of network users' behavior analysis, including network click flow analysis , computer and network security analysis and user structure analysis of Intranet. The key algorithm of behavior analysis system has been discussed and improved .The path cluster's method based on ISODATA algorithm is proposed in this paper, and we have gotten better experimental result. First the thought of Intranet users' structure analysis system prototype has been built;Then,such behavior analysis method is used in the intrusion detection and virus detection in the computer and network. This application is the trend of this safety field .We have detected the intrusion through finding Outlier.
