From April 19 to April 22, 2022, Locked Shields, the most critical international live-fire cyber defence exercise in Tallinn, Estonia. Since 2010, the NATO Cooperative Cyber Defense Centre of Excellence (CCDCOE) has been organising this annual event, putting the cyber capability of NATO member countries to the test. This exercise took more than six months to prepare to ensure its success. It aims to strengthen the collective digital defence across the Alliance and test the Allies’ skills. The participants had a unique opportunity to prove their ability to protect national civilian and military IT systems and critical infrastructure.
The Locked Shields 2022 exercise subjected around 5,500 virtualised systems to 8,000 live-fire attacks. However, the exercise is not as significant in its size as its complexity. The involved teams had to prove their ability to protect the entrusted critical infrastructure of an imaginary country and their effectiveness in reporting details about the situation on the digital battlefield, executing strategic decisions and solving forensic, legal and information operations challenges. For the first time, in 2022, the technical exercise also included the simulation of a central bank's reserve management and financial messaging systems. The main focus of the exercise was on the interdependencies of international IT systems.
This year, more than 2000 participants from 32 nations were involved. Twenty-four NATO member nations, including the Slovak Republic, took part in the exercise every year and were joined in 2022 by cybersecurity experts from the Czech Republic. Since there was interest from many nations, several nations joined forces to create joint teams like the Slovak-Czech, Lithuanian-Polish, and Estonian-Georgian ones.
The Slovak-Czech team was formed from experts in the armed forces, government organisations, and the private sector, including ESET. Twenty-nine of ESET´s security experts participated in the exercise, helping the SK-CZ team to fifth place overall and the top in two subcategories: forensics and reporting.
ESET is glad to have had the opportunity to join Slovakia in this exercise once more and thus prove itself as a valuable member and partner to the country.
"Once again, the team from ESET demonstrated its technical expertise at Locked Shields 2022 and helped the Slovak-Czech blue team achieve an excellent ranking. ESET's products had high incident detection efficiency and enabled us to respond to emerging threats in a short period proactively. A thank you to everyone involved for their participation and high level of professionalism," says the Director of the Cyber Defence Center of the Slovak Republic.
The need for digital security and locking shields is increasingly evident given current events like the invasion of Ukraine and the COVID-19 pandemic. As the global community becomes increasingly dependent on technology, malicious cyber actors are growing their efforts to attack both public and private sectors. In response, the Locked Shields exercise uses the latest technologies to train national teams within an exercise environment based on realistic scenarios.
