Welcome to Enterprise, a platform for open-source research and development projects originally established by the Center for Clinical Computing (now a part of Boston's Beth Israel Deaconess Medical Center).
We wrote a DB-backed, web-based front end for the popular Nessus network vulnerability assessment scanner originally for our internal use, but have released it under the GPLv2. Since then, it has been the inspiration for at least one commercial product. It is simply referred to as "Nessus PHP".
We like the TARPIT netfilter target, but its maintainer does not seem to be keeping up with recent kernel versions. So we've made our own unofficial patches. You can download them here.
