I. FRONT AND CENTER
---------------------
1.Time to Take the Theoretical Seriously
By Chris Wysopal
Software developers response to "theoretical" research is fundamentally broken. By now, everyone in the security industry knows about the Rogue CA presentation that Alex Sotirov and Jacob Appelbaum gave at 25th Chaos Communications Congress. It was one of the most interesting I saw all last year, and it's a good example of why software companies continue to be vulnerable to attackers
