Database Security Protection Based on a New Mechanism
The database security is one of the important issues that should take a complete attention from researchers. Although applying the traditional security mechanisms, the database still violate from both of external and internal users. So, the researchers develop a DataBase Intrusion Detection System (DBIDS) to detect intrusion as soon as it occurs and override its malicious affects. The previous work developed a DBIDS as a third party product which is isolated from the DBMS security functions especially access controls. The lack of coordination and inter-operation between these two components prevent detecting and responding to ongoing attacks in real time, and, it causes high false alarm rate. On the other hand, one of the directions that are followed to build a profile is the data dependency model.
