Analysis of Database Security Technologies

摘要：

Database is the carrier of the storing and managing of information, whose security is becoming more and more important with the development of the information technology. In this paper we start from the definitions and requirements of database security, discussing the problems of user authorization, access control, database encryption and auditing in detail, and analyzing the three approaches to improve the security of the database. At last, we try to give some proposals to the existing problems of the database security and point out the ways of research in the near future.
