Multilevel database security is a security management which provides clearance levels for users. It also provides classification labels for the data. Most multilevel secure database systems employ the mandatory access control as proposed by Bell and La Padula. Most research works apply the multilevel secure technique to conventional relational databases. This research project proposes an extension to the mandatory access control so that it suits our application requirements. Moreover, the support of bitemporal database features is also included. Both valid time and transaction time are added to the already complex multilevel secure relational database. Integrity rules for this new model are introduced and finally, an extension to the SQL language is proposed to be used on the data model.
