The NATO Cooperative Cyber Defense Center of Excellence (CCDCOE) annual cyber defence exercise Locked Shields 2023 started in Tallinn.
For four days, more than 3,000 participants from 38 nations will protect real computer systems from real-time attacks, and train tactical and strategical decision-making in critical situations. In addition to defending systems, teams must report incidents, execute strategic decisions, and solve forensic, legal, and media challenges.
