Demystifying the Chinese Hacking Industry: Earning 6 Million a Night - An Interview with a Member of the Chown Group (COG) about the billion dollar hacking business in China

Free Online security course (LearnSIA) - A Call for Help - The Survivability and Information Assurance (SIA) course was originally developed by a team at Carnegie Mellon, led by Lawrence Rogers (http://www.cert.org/sia/).
