Problem setting. Security issues are importantfor contemporary international relations research, since security has been and remains one of the most important aspects in the functioning of international relations. Ensuring security is seen as an important task for both a state and the international community in the broad sense of the term, in particular for the EU. In today’s context, the problem of information security of the individual, the state and the society is fundamentally relevant as it needs, primarily, a complex reflection, taking into account the realities of the present. In addition, continuous monitoring of the security situation in the information field, the ranking of threats by the degree of influence on national interests, the rational redistribution of forces and the means to neutralize threats are urgently needed.Recent research and publications analysis. Problems of European politics and defense are constantly in the center of attention of Western scientists, first of all Laura Chappell, David J. Galbreath, Jocelyn Mawdsley, Robert McCabe, Hugo Meijer, Deborah Sanders, Ian Speller, Marco Wyss, and others. In the Ukrainian literature, some solutions to this problem are found in Ya. Tymkiv’s manual, in the encyclopedic dictionary-directory «Modern Political Vocabulary», in the Glossary of the Encyclopedic Dictionary of Information Security, articles by Yu. Bytyak and I. Yakovyuk, M. Dmytrenko, E. Nikipelova,O. Poshedin, O. Sosnin and O. Dzioban, M. Trebin which the author of the paper researches and identifies previously unsolved parts of the general problem the article is devoted to.Paper object: to analyze the term «security», to identify the place of security in the European security and defense policy, to characterize the peculiarities of the problem of the Euro-Atlantic security space formation.Paper main body. In the article, based on the conceptualization of the security problem in the aspect of international political issues, the definitions of the security by domestic and foreign scientists are explored. Particular attention is paid to information security, which requires, first of all, a comprehensive understanding of the today’s realities. The evolution of the EU Common Security and Defense Policy, its current interpretation in the EU’s Global Foreign and Security Policy, has been traced. The main security priorities were identified, namely, defense, counter-terrorism, cybersecurity, energy and strategic communications. Special attention is drawn to the problem of creating the Euro-Atlantic security information space, i.e., the space of a dialogue between Ukraine and the NATO, which should accompany the necessary reforms in Ukraine in order to bring it closer to Euro-Atlantic standards.Conclusions of the research. Therefore, in the modern science of international relations there is no definition of security that would satisfy both domestic and foreign scientists. This is explained by the fact that certain components of the security content acquire a certain value or lose it, depending on the internal situation in the country and the international situation. The problem of information security which requires, first of all, a comprehensive understanding of the present realities is ofparticular importance in today’s context.The contours of the EU Common Security and Defense Policy began to be defined in the 1990s, and its current interpretation is reflected in the EU’s Global Foreign and Security Policy, 2016. Defense, counter-terrorism, cybersecurity, energy and strategic communication are the main security priorities. The issue of creating a Euro-Atlantic security space that is the space of a dialogue between Ukraine and the NATO, which should accompany the necessary reforms in Ukraine in order to bring it closer to Euro-Atlantic standards is of utmost importance.

В статье на основе концептуализации проблемы безопасности в аспекте международно-политической проблематики исследованы определения безопасности отечественных и зарубежных ученых. Особое внимание уделяется информационной безопасности, которая требует, прежде всего, комплексного осмысления с учетом реалий. Прослежена эволюция общей политики безопасности и обороны ЕС, современная ее интерпретация в Глобальной стратегии внешней политики и политики безопасности ЕС. Отмечено, что приоритетными вопросами безопасности определены: оборона, борьба с терроризмом, кибербезопасность, энергетика и стра­тегические коммуникации. Определенное внимание уделяется проблеме создания евроатлантического информационного пространства - пространства диалога Украины и НАТО, которое должно сопровождаться проведением необходимых реформ в Украине с целью приближения ее к евроатлантическим стандартам.
