Open Web Application Security Project (OWASP)

OWASP is a non-profit organization dedicated to the advancement of web-application security. I have been involved with OWASP in the past as an author of a few chapters of the Guide to Building Secure Web Applications. I have also donated Yasca to OWASP; it is currently an "Alpha Project". Most recently, I started a new project, called the OWASP Vulnerability Data Model Project, which aims to create a common data model for applications to share vulnerability information. OWASP is a great organization to get involved with; they have chapters all over the world and the mailing lists are usually very active.
