The need for colleges to graduate students who understand computer security is growing. The Internet Crime Complaint Center, a partnership of the FBI; the National White Collar Crime Center; and the Bureau of Justice Assistance, in the Department of Justice, reported more than 90,000 crimes in 2007, with reported financial losses of almost $240-million. This article reports on the National Collegiate Cyber Defense Competition held last month in San Antonio. The goal of the competition is to increase interest in computer security and improve training for network defenders. Participants of the competition are composed of 56 teams that had entered state and regional contests this spring. The top six had been flown to San Antonio for the national finals. Each team was given a fictional business network created by the contest organizers. Over the next three days, the teams had to defend their networks from a set of elite hackers--in reality, eight security professionals. At the same time, organizers peppered the students with requests to expand the network and add new business capabilities. The competition reflects a shift in computer-security education. College students learn real-life lessons in Internet security when they go up against hackers in the competition.
