Cyber Storm 2020: National Cyber Exercise


Cyber Storm 2020, sponsored by the Cybersecurity and Infrastructure Security Agency (CISA), was held in August 2020. Cyber Storm 2020 brought together the public and private sector to simulate response to a cyber crisis impacting the nation’s critical infrastructure. Cyber Storm 2020 was the nation’s most extensive exercise to date, including over 2,000 players nationwide participating in three days of live exercise play. Cyber Storm 2020 represented the seventh iteration of the National Cyber Exercise

Enhancing Cyber Incident Response Capabilities

The dynamic nature of cybersecurity threats demand continual review and assessment of the nation’s cyber incident response capabilities. Cyber Storm provides a unique venue where aspects of the nation’s critical infrastructure – federal, state, and local entities, along with the private sector owner and operators – can examine collective cyber incident response capabilities with the goal of identifying areas for growth and improvement.

Cyber Storm 2020 focused on:

  • Build upon the outcomes of previous exercises and changes to the cybersecurity landscape;
  • Evaluate and improve the capabilities of the cyber response community;
  • Promote public-private partnerships and strengthen relationships; and
  • Integrate new critical infrastructure partners, while providing an opportunity for Cyber Storm veterans to return.

Past Highlights

  • Cyber Storm I, 2006, marked the first time the cyber response community came together to examine the national response to cyber incidents.
  • Cyber Storm II, 2008, exercised individual response capabilities and leadership decision making.
  • Cyber Storm III, 2010, focused on response according to national-level frameworks and provided the first operational test CISA Central.
  • Cyber Storm IV included 15 building block exercises between 2011 and 2014 to help communities and states exercise cyber response capabilities for escalating incidents.
  • Cyber Storm V, 2016, included more than 1,000 distributed players and brought together new sectors, including retail and healthcare participants.
