From April 8 to 12, 2019, the world's largest cybersecurity training exercises Locked Shields are held in Tallinn, reported the NATO Cyber Defense Center.
"The annual exercise is a unique opportunity for national cyber experts to practise protection of national IT systems and critical infrastructure under the intense pressure of a severe cyberattack," stated NATO Cyber Defense Center in Tallinn.
The goal of the exercises is to train the experts in the field of protecting information systems and critical infrastructure from cyber-attacks. Locked Shields are the world's largest cybersecurity exercises, held annually since 2010.
"The organizers integrate the technical and strategic game, enabling participating nations to practice the entire chain of command in the event of a severe cyber incident, from strategic to operational level and involving both civilian and military capabilities," reports the Cyber Defense Center website.
According to the scenario, a fictional island country, Berylia, is experiencing a deteriorating security situation during national elections. All this coincides with coordinated cyberattacks causing severe disruptions in the operation of the electric power grid, water purification systems, public safety networks, and other critical infrastructure components.
