There is an increased urgency today to ensure that security and proper access control for database. With sensitive information, database needs to provide a security access control policy that is tightly integrated into database modeling to ensure the control. For mandatory access control, users are grouped into clearance, and data are grouped by their classifications. Mandatory access control is applicable in systems containing large amounts of extremely sensitive information with very strict access and security requirements. These systems that implement mandatory access control policies are known as multilevel secure systems (MLS). MLS model required the key attributes to have the same values at all security levels. This requirement excluded the possibility of users at different security levels from seeing different values for the key attributes. In this paper, we identified the shortcoming as the cover story can be used in MLS for non-key attributes only and proposed a conceptual approach for extending the multilevel secure to relational database. The lacks of semantics or incomplete semantic definitions are presented.
