Security structure of the European Union

Purpose of the study: The object of the analysis is to assess the effectiveness of the European Union in ensuring internal and external security.  Methodology: the article was prepared based on critical analysis of literature and documents and uncontrolled observation method. Main findings: the established institutions and agencies within the EU may appear to be adequate and competent. However, in reality, their effectiveness and coherence of activities aimed at fulfillment of common safety objectives often fail to meet expectations, whereas systems and operating procedures differ from the solutions used in practice. The multidimensionality of security, and above all the evolution of the challenges in terms of the ever-changing security environment, will require the EU to establish new institutions or equip existing ones with new competences. Application of the study: security forecasting based on the main variables emerging in the contemporary security environment and adapting the EU institutional security architecture to new threats. Original/Novelty of the study: the subject matter is very current, being a member of the EU, we participate in the identified problem.
