Database has been accessed by more and more multiple users,which leads to the problem of multi-user security auditaccess to the database,the users access to the database is broadly divided into three categories:the legal operations to the data-base by legitimate users,the illegal operation to the database by legitimate users and the operations of the database by illegitimateusers.For these three different accesses to the database by these two different users,the strategy of security audit mechanism wasproposed based on user behaviors.The user behavior to be monitored and tracked by the audit,and then create a model of the userbehavioral characteristics,the database will carry out safety audits according to the model when the user access to this databaseagain.In SQL Server2005 example,further explore the security auditing mechanism of traditional database as well as the success-ful application of the protection of database security mechanisms based security auditing user behavior.
