The global legal order governing the security of states, international organizations or individuals is heterogeneous and multifaceted in nature. It clashes between the norms of international, EU and internal law. The genesis of the European Union lacked the legal basis for the creation of internal and external security structures, while normative efforts were directed towards the economic development of the organization. At the same time, within the framework of the UN, normative solutions were introduced for the prevention of breaches of peace, spheres of security within the supranational framework. Both the European Union and members of the United Nations must introduce normative solutions to combat threats, including terrorist threats, as actions to protect the European system of values and the system of the United Nations.
