Secure Xenix™ is an experimental system designed to run on IBM PC/AT workstations. Like Xenix, it is a Unix™ System V implementation on the PC/AT workstation; unlike Xenix, it eliminates the Unix security deficiencies and it enhances security policies. In this paper, we present the design features of Secure Xenix, their integration within Xenix, and some of the lessons learned from this experiment to date.
