The SecurityFocus assets, including the BugTraq mailing list, has a long history of providing timely information on the latest vulnerabilities, security vendor announcements, and exploit information. We are forever grateful to those who created, maintained, and contributed to the archive – many of us have connected and learned from each other through these lists. The history of the list and the sharing of the information has contributed to ensuring that we are building the information security community to be something stronger. Community contribution is one of the foundations to building a stronger Information Security force.
