Secure database design panel

Abstract

It is shown that tuple-level mandatory protection and relation-level discretionary protection are adequate for supporting the security requirements of the RADC (Rome Air Development Center) homework problem, a 22-page specification for a multilevel secure database. The tuple-level granularity of control induced database decomposition to provide tuples of uniform classification. Likewise, the discretionary protection on relations induced database decomposition to meet the discretionary requirements. While there were a few examples in which tuple-level discretionary controls would have been desirable, this slight inconvenience is balanced by the lower overhead of relation level discretionary controls.<>
