Secure database design: an implementation using a secure DBMS

G.W. Smith presented a homework problem at the second annual RADC (Rome Air Development Center) Database Security Workshop and challenged the workshop attendees to provide a prototype database design. In the present work, it is shown that most of the MLS (multilevel secure) design requirements in the homework problem could be implemented on the Sybase Secure SQL Server with no noticeable performance degradation. Most of the data-driven classification constraints are readily solved by the security mechanisms offered in a trusted DBMS (database management system)
