POSSE project

The Portable Open Source Security Elements, or POSSE project, was a co-operative venture between the University of Pennsylvania Distributed Systems Laboratory, the OpenBSD project and others. It received funding through a grant from the United States Defense Advanced Research Projects Agency, or DARPA. The project's goal was to increase the security of some open source projects, including Apache and OpenSSL. The project ran from 2001 until April 2003, when the grant from DARPA was prematurely terminated.
