Develop Secure Database System with Security Extended ER Model

摘要

Database system security is desired for acutely today. But it is difficult and expensive to develop secure database system because the developers usually find it difficult to design a consistent and complete database structure. To solve the problem we focus on the research results on both DB design model and the security mechanisms. The secure database system development will be simplified greatly by combining database design methodology and information security technique. So we made the effort to combine the security control mechanisms (e.g. MAC) and database develop model—Entity Relation (ER) model to construct a Security Extended ER (SEER) model. The security of the database system developed with SEER model is analyzed at the last part in the paper. The research and applying of SEER model puts forward a new ideal about secure database system development.
