....vulnerabilities. This paper describes these general security concerns, the manner in which the Mach 3.0 kernel addresses each concern, and the manner in which DTMach addresses each concern. This paper does not describe other aspects of the DTMach design. The interested reader is referred to [8] for a description of the complete design. Although familiarity with the Mach 3.0 kernel and DTMach design is helpful in reading this paper, Section 2 provides a brief overview of Mach and DTMach that contains enough detail to understand the issues discussed in subsequent sections. DTMach uses ....

....all the same requests and will find the same general semantics for all those requests. To address security issues, variants of a small set of kernel entry points have been proposed. In this paper we discuss the general issues associated with the proposed changes. The interested reader can consult [8] for detailed descriptions of the changes. There are four general concerns that lead to extensions of the existing Mach kernel interface. 1. Definition and management of security contexts. 2. Association of security contexts with basic DTMach entities. 3. Access to security context information. 4. ....
