It is well understood today that the semantics of data must be taken into account in order to specify effective access control policies. Also, techniques for data integrity and availability specifically tailored to database systems must be adopted. In this respect, over the years the database security community has developed a number of different techniques and approaches to assure data confidentiality, integrity, and availability.
