Database Intrusion Detection System Research With Realizes

With the fast development of Internet, computer network has played the more and more important role in the society, economy, culture, and people's life. More and more governments, business and finance having their own databases connected to the internet. Recent report shows that there is a large increase in the attack to these network databases. Then current security is focuse network database security. So we need to study intrusion detection technology on databases to intensify the security.At first this paper introduces the development process of intrusion detection system. Then we describe the function, model and taxonomy of intrusion detection systems, particularly discuss the model of intrusion detection system. And the framework and standardization of intrusion detection system are thoroughly discussed in this paper. The problem san d future of intrusion detection system are put forward in this paper. The international standard of database security is also given here and then the security mechanism of SQL Server is detailedly discussed. The application of Misuse detection technology and anomaly detection technology in SQL Server are talked about thoroughly in this paper. We show more emphasison the anomaly detection technology based on data mining. Finally, the constructing process of database intrusion detection is detailedly discussed here. By use of Aprior association rule algorithm, the user's historical data are mined. We also give the test data in this paper .By comparing the similarties between the history profiles and present ones we can detect the anomaly in present profiles. Result of experiments shows the differences between them.
