The dynamic expansion of the quantitative and qualitative parameters of Internet usage on a global scale has led to the rapid formation of cyberspace. While the use of cyberspace resources provides significant informational, communicative, and productive opportunities, it also poses systemic threats due to their unethical (and often criminal) exploitation. Ukraine, as a participant in international processes, along with its citizens, has fully experienced the threats arising from the misuse of global cyberspace amidst the full-scale military invasion of the country. These circumstances have heightened the relevance of studying the theory and practice of legal regulation concerning the functioning of the cybersecurity system in Ukraine, which constitutes the goal of this publication. The research methodology included cognitive, logical, terminological, comparative, systemic, historical, and statistical methods. The study analysed the concept of “cybersecurity” and identified types of threats to national security linked to the state's integration into the global cybersecurity system. It examined the elements constituting legal relations in the field of cybersecurity (subject, object, content, and legal facts), characterised the state of legal regulation in Ukraine's information security sector, and reviewed the content of Ukraine's Cybersecurity Strategies of 2016 and 2021. The study concluded that building an effective cybersecurity system in Ukraine requires government institutions to clearly establish state policy in the sector and promptly respond to the rapid evolution of the information space. The genesis of the cybersecurity system itself must be accompanied by continuous advancements in the protection and defence sectors. Thus, the practical significance of the research stems from the necessity to analyse the essence and state of legal support for cybersecurity in Ukraine under modern challenges to the national security system during wartime, as well as to forecast and plan the future development of the state's cybersecurity policy
