The Chinese Wall Security Policy by Dr David F.C. Brewer and Dr Michael J. Nash
Saved by uncleflo on September 7th, 2014.
Another concept is that of Chinese Walls, a security model that is also referred to as [the Brewer and Nash Model][8]. From their paper, the model can be described within a database organization as three intermittent levels. At the lowest level, we consider individual items of information, each concerning a single corporation. In keeping with BLP, we will refer to the files in which such information is stored as objects. At the intermediate level, we group all objects which concern the same corporation together into what we will call a company dataset. At the highest level, we group together all company datasets whose corporations are in competition. We will refer to each such group as a conflict of interest class.
