Thousands of cybersecurity experts from across the country and abroad will converge this week for Cyber Storm III, a three-day-long exercise designed to evaluate America's ability to respond to a cyberattack. The exercise will offer the first test of the recently devised National Cyber Incident Response Plan by simulating a large-scale assault on the nation's critical infrastructure, according to a news release. Participants are expected to include representatives from federal agencies, 11 states, 60 private companies and 12 countries. Cyber Storm exercises previously were held in 2006 and 2008. — DK
