DBST: A develop toolkit for database security

Database system security is desired for acutely today But it is difficult and expensive to develop secure database system because it is difficult to design a consistent and complete database structure. To solve the problem we focus on the research results on both software engineering such as CASE technique and the security mechanisms. The secure database system development will be simplified greatly by combining database design methodology and information security technique to implement a develop toolkit for database security. So we made the effort to combine the security control mechanism (e.g. MAC) and database develop model-Entity Relation (ER) model to construct a Security Extended ER (SEER) model and design a toolkit named DBST based on the model. The security of the database system developed by DBST is analyzed. The research and applying of DBST puts forward a new ideal on secure database system development.
