Cybersecurity in the context of cyber resilience: Ukrainian experience

Abstract

Abstract. With the development of digital technologies, the issue of cybersecurity is becoming increasingly relevant in various sectors of society. In the context of national security, cyber resilience plays a crucial role in the ability of systems and organizations to withstand cyberattacks and quickly recover from them. Ukraine’s experience in this area is unique due to the constant cyber threat from a neighboring state, which began long before the full-scale invasion in 2022. However, the stated problem has not been properly analyzed which is the purpose of our report. After the annexation of Crimea in 2014, Ukraine faced numerous cyberattacks targeting critical infrastructure, government institutions, media, and private businesses. One of the most high-profile incidents was the Petya virus attack in 2017, which affected thousands of computers worldwide but was primarily directed at Ukrainian targets. This incident revealed weaknesses in the country's cybersecurity systems and spurred efforts to strengthen protective measures.
