Black Hat: Security Conference or Burglar School?
July 31, 2003
By Larry Seltzer
For instance, there's the class "Attacking and Securing UNIX FTP Servers." This one-sided training reminds me of the people who publicly release exploit code for a vulnerability before it has been patched. Such people are part of the problem in spite of their puerile excuses. Just because people ought to look where they're going doesn't make it right to throw banana peels on the sidewalk. If someone trips you are to blame.
Is Seltzer blind? The class title clearly says attacking AND securing, yet he calls it "one-sided training".
