Design of Network Behavior Analysis System Based on Association Rules Mining

With the rapid development of the computer network technology, Internet application further

popularization, people in the work and the life rely more and more on various network applications and

services. At the same time, some network using issues also will appear, is mainly shown in two aspects: one

is excessive network entertainment behavior, the application USES of a lot of network resources and affect

the normal network services; On the other hand is network users of harmful behavior, these actions often

brings serious the problem of network security. Especially in the campus network, the user groups are mainly

students, they are more likely to indulge in Internet chat, online games and other entertainment behavior, and

often due to inappropriate network behavior and cause safety issues, or because of interest and curiosity and

actively carry out some harmful network behavior. To solve these problems, the study and analysis of the

user's network behavior, especially students groups of Internet behavior, limit harmful network behavior

occurs, for effective management of campus network resources, strengthen the campus network security

have realistic significance.

Based on the use of association rules mining technology, on the basis of analysis of the user access to

the network through behavior to get the user behavior patterns, judge behavior orientation, abnormal

behavior of the network behavior analysis system for research and design.

1 network behavior analysis in the paper

Behavior analysis is originally in the field of psychology research a concept, because it to all sorts of

social activities have very good guiding value, so the application in many fields. Along with the computer

network appear and popularization, domestic and foreign scholars began to study the characteristics of

network users behavior and law. Network users have different interests and behavior habits, and in the

Internet corresponding network access behavior also inevitable with the features of their own, to this kind of

the analysis of characteristics of the network behavior analysis and exploration is the focus of research, the

research methods mainly through the user access to the server log analysis, mining users in the international

network access the behavior of features. Network behavior analysis mainly used in Internet use preference,

network security audit, intrusion detection analysis, can realize optimized website design, security network

security, leading and managing the abnormal behavior of network effect.

Most of the current network behavior analysis research mainly are based on data mining technology,

network behavior analysis process in fact is a network behavior from a large number of data in get valuable

information data mining process, but the network behavior analysis method analysis emphasis and analysis

object is different, mainly including: user features analysis, correlation analysis, classification and predicting,

abnormal analysis, TopN analysis, IP address analysis, hits analysis, Web log analysis, etc. In the network

behavior analysis system, the paper association rule mining algorithm for the correlation analysis, mining

produce behavior model added to the behavior patterns in the library, and based on similarity methods to

than behavior model and identify anomalies behavior.

2 network behavior analysis system design

The system is mainly used in the campus network LAN environment, through the client Agent

acquisition all users of network behavior of raw data, and the original data format for user behavior

description format, sent to the server, form for data mining training data set, then the algorithm for mining

association rules of behavior model the relationship between the characteristics are analyzed, extract the user

behavior model information, establishing user behavior model library. For a particular user group, can

collect real-time their network behavior data, format as a test data set and after user behavior patterns of

behavior pattern of library than normal, if discovery is unusual behavior can be to a particular user's ZHANG Xin, LI Kun-lun·Design of Network Behavior Analysis System Based on Association Rules Mining·College

computer operation management. The system includes three modules: data acquisition and formatting

module, behavior pattern formation module and behavior model than module.
