TrustedBSD: Adding Trusted Operating System Features to FreeBSD
Robert N. M. Watson, FreeBSD Project, NAI Labs
Abstract
Trusted operating systems provide a ``next level'' of system security,
offering both new security features and higher assurance that they
are properly implemented.
TrustedBSD is an on-going project to integrate a number of trusted
OS features into the open source FreeBSD operating system, and involves
both architectural and development process improvements.
This paper describes how the open source development practices of the
FreeBSD Project impacted the design and implementation choices for
these features, and describes lessons learned that will influence future
work.
Several key TrustedBSD features are discussed as examples of how new
security services may be introduced in such an environment.
