Here’s an account from the Department of Homeland Security on its conduct of “Cyber Storm VI: Testing the Nation’s Ability to Respond to a Cyber Incident”.
DHS has a link to the Cyber Storm exercise series at www.dhs.gov/cyber-storm. The exercise “involved more than 1,000 members of the private industry, government and international partners who participated in a three-day distributed exercise that focused on the critical manufacturing and transportation sectors. The exercise evaluated and improved the capabilities of the cyber response community, informed preparedness and resilience planning efforts, and evaluated the effectiveness of the National Cyber Incident Response Plan in guiding response. Growth in this community of partners acknowledges the increasing value of information sharing and the benefits of exercising their organizations cyber response plans.”
If active, beyond precautionary measures in cyber security are a priority in your organization, we’d suggest contacting DHS about possibly participating in the next such exercise in 2020.
