Nemesis

Stanford University and MIT researchers are looking to make Web applications more secure by preventing authentication and access control vulnerabilities. explains that "Nemesis combines authentication information with programmer-supplied access control rules on files and database entries to automatically ensure that only properly authenticated users are granted access to any privileged resources or data." It also "constructs a shadow authentication system to track user authentication state through an additional HTTP cookie." Nemesis has been tested out on applications such as PHP iCalendar and Linpha Image Gallery.
