Sunday, July 20, 2008: 4:00 pm (Turing): Access control systems are widely used in security, from restricting entry to a single room to locking down an entire enterprise. The many different systems available – card readers, biometrics, or even posting a guard to check IDs – each have their own strengths and weaknesses that are often not apparent from the materials each vendor supplies. This talk provides a comprehensive overview of 20 different access control technologies that focuse on weaknesses (particularly little known or not-yet public attacks) and other points that a buyer would not likely get from a vendor. Also presented will be a model for thinking about access control systems in general that will provide a useful framework for evaluating new or obscure technologies.Hosted by Eric Schmiedl and Mike Spindel
