The design and implementation of database audit system framework

For the information system, Database acts an important role in it. How to find a way to audit the operation of the database is becoming more and more important. An effective database auditing system can not only reduce the potential security risk, also make it possible to trace the source when errors happen. In this paper, we design and implement an effective audit framework. To avoid causing any database performance delays, bypass mode is especially useful for the auditing system. Compared with the traditional audit system, our approach has more advantages for example using zero-copy to acquire and reorganize data. In addition, we have a flexible policy to audit more effectively.
