LEAST PRIVILEGE IN SEPARATION KERNELS

Timothy E. Levin, Cynthia E. Irvine, Thuy D. Nguyen

Abstract

We extend the separation kernel abstraction to represent the enforcement of the principle of least privilege. In addition to the inter-block flow control policy prescribed by the traditional separation kernel paradigm, we describe an orthogonal, finer-grained flow control policy by extending the protection of elements to subjects and resources, as well as blocks, within a partitioned system. We show how least privilege applied to the actions of subjects provides enhanced protection for secure systems.
