Ever wonder how a popular open-source content management system roots out bugs and patches vulnerabilities? The folks behind the Drupal Security Report and Mogdesign created a slick graphic that takes a nod from the game of Life -- the Milton Bradley board game, not the simple simulation of digital organisms. Drupal posts an active development community of 15,000 programmers and more than 700,000 users, according to the graphic. The security team is always on call to assess vulnerabilities and fix issues.
