ABSTRACT
Better be despised for too anxious apprehensions, than ruined by too confident security.
—EDMUND BURKE
From the very first chapter this book has been about how computer scientists think. Unfortunately, a few computer scientists use their skills to do harm. The problem is that just as computing technology can be used to solve our problems, so too it can be used to steal or vandalize. It is this possibility for abuse of technology that has elevated the importance of computer-related security.
