Cyber Defence in NATO and in the EU

Abstract

Over the past two decades, the growing hybrid and significant cyber security threat has affected both the Member States of the European Union (EU), the North Atlantic Treaty Organization (NATO) and their own systems. European governments had to take steps to develop cyber security policies at national level, while simultaneously
pooling their sovereignty through the North Atlantic Treaty Organization and the European Union to strengthen their protection. The question often arises as to what is the difference and the similarity between the two organizations, and is it necessary for both if there are overlaps? The purpose of this publication is to show how cyber security threats affect the organizational structure and strategic environment of the EU and NATO.
