New Paradigms for Unix Security

Paul McNabb - Argus Systems Group, Inc.

Apr 18, 1997

Abstract

The security problems associated with Unix are inherent in the system architecture which has remained fundamentally unchanged for nearly 20 years. There exist security technologies that can significantly reduce the threats to Unix systems, but require kernel-based changes. In particular, privileges, mandatory access controls (MAC), capabilities, and authorizations are important tools in securing critical systems, such as servers and firewalls.
