ABSTRACT. Cyber is the battlefield that nations, enterprises and citizens need to face in the next years. New paradigms and new threats are growing daily. During the cold war only a limited number of countries had the economic and technology capacity to build “weapons” to impose their role.The United States invented the internet, but the future of cyberspace and its leader is not yet defined. Now 29 countries have units able to provide offensive operations through cyber techniques and 49 have purchased malwares. The global connection and nature of internet, that provide itself instrument to hide who is behind an attack and determine whom to punish, will leave several questions open. This paper tries to provide an overview of these issues leaving some questions open to government and institutions.
