The TrustedBSD MAC Framework: Extensible Kernel Access Control for FreeBSD 5.0
Robert Watson, Wayne Morrison, and Chris Vance, Network Associates Laboratories; Brian Feldman, The FreeBSD Project
We explore the requirements, design, and implementation of the TrustedBSD MAC Framework. The TrustedBSD MAC Framework, integrated into FreeBSD 5.0, provides a flexible framework for kernel access control extension, permitting extensions to be introduced more easily, and avoiding the need for direct modification of distributed kernel sources. We also consider the performance impact of the Framework on the FreeBSD 5.0 kernel in several test environments.
