The Open Source Security (oss-security) wiki and mailing list are a product of co-operation amongst various open source software vendors, projects, and researchers. The purpose of the oss-security group is to encourage public discussion of security flaws, concepts, and practices in the Open Source community.
The mailing list and wiki are graciously provided by the Openwall Project.
Feel free to join us on #oss-security on the Freenode IRC network.
