A tutorial on secure database systems

Database security plays an important role in the overall security of information systems and networks. This is both because of the nature of this technology and its widespread use today. The development of appropriate secure database design and implementation methodologies is therefore an important research problem and a necessary prerequisite for the successful development of such systems. The general framework and requirements for database security are given and a number of parameters of the secure database design and implementation problem are presented and discussed in this paper. A secure database system development methodology is then presented which could help overcome some of the problems currently encountered.
