The TrustedBSD Project is an open source community developing
advanced security features for the open source FreeBSD operating system.
Started in April 2000, the project developed support for extended
attributes, access control lists (ACLs), UFS2, OpenPAM, security
event auditing, OpenBSM, a flexible kernel access control framework,
mandatory access control, and the GEOM storage layer.
The results of this work may be found not just in FreeBSD, but also
NetBSD, OpenBSD, Linux, and Apple's Mac OS X and iOS operating
Today, the project continues to maintain and enhance these
mature features in FreeBSD.
The TrustedBSD Project originally targeted trusted operating system
functionality required by the Common Criteria for Information
Technology Security Evaluation (CC). Work has gone significantly
further, including research and development into operating system
security extensibility, and work on local and distributed file
systems as required to meet security goals.
This web site provides development information about TrustedBSD,
including early access to source code and on-going development work,
documentation and papers, historical information, and more. The
TrustedBSD Project also hosts a number of mailing lists for discussion of on-going
work as well as user support.
The TrustedBSD Project is made possible through generous sponsorship
and support from a variety of organizations, including the Defence
Advanced Research Projects Agency (DARPA), the National Security
Agency (NSA), Network Associates Laboratories, Safeport Network
Services, the University of Pennsylvania, Yahoo!, McAfee Research,
SPARTA, Inc., Apple Computer, Inc., nCirce Network Security, Inc.,
Google, Inc., the University of Cambridge Computer Laboratory, the
FreeBSD Foundation, and others.
