Abstract

The Distributed Trusted Mach (D TMach) programis developing a design for a high-assurance, secure,distributed system based on Mach. To achieve thisgoal, it is first necessary to identify the general threatsagainst which DTMach must protect. The next stepis to identify control mechanisms that are sufficientto protect against each of the threats. The DTMachdesign makes extensive use of type enforcement in addressing the threats. This paper describes the generalthreats and the countermeasures provided by DTMach.Doing so provides more evidence of the usefulness oftype enforcement in general and the high assuranceprovided by the DTMach type enforcement policy.
