The article is devoted to the study of a set of problems of European security policy, in particular the analysis of the new challenges to the priority directions of its development. It is noted that the current institutional system of European security policy is undergoing serious challenges associated with profound changes in international relations. The systematization of various aspects of EU security policy according to the following methodological approaches is proposed: the theory of behaviorism, the theory of political realism, liberal-idealist paradigm, postmodernist theory, alternative theoretical models. The conceptual substantiation of the development of European integration in the field of security and defense policy is the EU strategies, which are developed in accordance with current challenges and threats. It is proved that the real institutional changes in the EU foreign policy occurred after the entry into force of the Lisbon Treaty and the establishment of the European External Action Service. The European Security Strategy (2003), the Global Strategy of the European Union (2016), the Security Union Strategy (2020) were analyzed, in particular, new challenges for the European security system and priority areas of EU security policy were identified.

Based on the analysis, the most pressing challenges, risks and threats are identified, the probability of which is considered high for the EU until 2025.
