EU Digital Sovereignty

Today ensuring data security is becoming one of the priority areas of EU policy. In February 2020, the EU adopted the Data Strategy aiming at strengthening its leadership in a digital society. Although the strategy sets primarily economic goals, the problem of ensuring digital sovereignty occupies an important place. The purpose of this study is to examine the EU information security policy, starting from the concept of "Westphalian sovereignty" proposed by the S. Krasner. This concept found coverage in the works of M.M. Lebedeva. S. Krasner defines "Westphalian sovereignty" as the completeness of state power within the borders and the absence of other subjects of power. Analysis of the EU strategy in the field of information security and big data allows us to conclude that the EU emphasizes the need to limit the “Westphalian sovereignty” within the framework of an integration structure, and not individual member states. This contributes to understanding of the trends of evolution of state sovereignty in the context of globalization and the modern data revolution.
