Security in Database Systems - from a Researcher’s View

Database security has been the subject of active research for the past several years. In the last five years, rapid progress has been made in defining what, security means for such systems and in developing laboratory prototypes and even products that meet those definitions. However, much more work remains to be done in certain key re- search areas. This paper provides an overview of the database security issues for both mandatory and discretionary security and describcs areas of ongoing research.
