The document describes the OWASP A&D Project, which aims to help web application developers acquire skills in finding and fixing vulnerabilities through a deliberately vulnerable web application platform. The platform has two modes: standalone for self-study, and competition for events. In competition mode, an operator's server automatically attacks participants' web applications and checks for vulnerabilities on a schedule. Participants earn points for passing checks and lose points for failures. Their scores and rankings are viewable through a web interface. The project aims to improve security skills through repeat practice on a shared environment.
