Cyber Storm III Department of Homeland Security

The Department of Homeland Security's (DHS) National Cyber Security Division (NCSD) held Cyber Storm III (CS III), a comprehensive and dynamic cybersecurity exercise from September 27 through October 1, 2010. Cyber Storm is the DHS' capstone national-level. This biennial event represents the Nation's most extensive cybersecurity exercise of its kind and is an element of ongoing efforts to assess cybersecurity preparedness; examine incident response processes, procedures, and information sharing mechanisms; and identify areas for improvement - absent the consequences of an actual incident. This national-level exercise included participation from eight Cabinet-level departments, 13 states, 12 international partners, and 60 private sector companies and coordination bodies. Together, these entities participated in the design, execution, and post-exercise analysis of the largest, most comprehensive government-led, full-scale cyber exercise to date.
