Gen. Keith B. Alexander Seeks Hacker Collaboration At Defcon

Gen. Keith B. Alexander, the director of the National Security Agency, asked hackers for help securing cyberspace when he spoke at the Defcon conference late last month. "This is the world's best cybersecurity community," said Alexander, who also heads the U.S. Cyber Command. "In this room right here is the talent our nation needs to secure cyberspace."
