The article presents an analysis of cybersecurity legislation in the member countries of the Eurasian Economic Union (EAEU), focusing on Russia, Kazakhstan, Kyrgyzstan and Belarus. In four parts of the article, the main aspects of the legal regulation of cybercrime in each of these countries are considered, as well as problems and shortcomings in legislation are identified. Outdated norms and ambiguities in legislation that are unable to adequately respond to modern challenges of cybercrime are discussed. The importance of an integrated approach to cybersecurity is emphasized, which includes not only legal regulation, but also technical, organizational and educational measures. It is proposed to conduct a more in-depth analysis and comparison of legislation to identify common trends, differences and the effectiveness of measures taken in the fight against cybercrime.Aim. Analysis of the legislation of the Eurasian Economic Union (EAEU) member states in the field of cybersecurity and cybercrime prevention, identification of common trends and differences, evaluation of the effectiveness of measures taken, and determination of directions for further improvement of cybersecurity in the region.Tasks.
