Cyber foreign policy is a new term, which defines states actions regarding cyberspace. This thesis defines that term and provides an overview on the central challenges of internet regulation, human rights, cybersecurity and digital diplomacy. The strategies of Austria, Germany, the European Union, the United States of America, Russia and China were compared for these topics. The state?s approaches were assessed in regard of international law, international customary law and soft law.The states try to extend their influence on regulation and functionality of the internet, which is currently realized with a multi-stakeholder approach. In summer 2013 it became publicly known, that many states fund internet surveillance programs. I researched on the two fundamental human rights of protection of privacy and freedom of speech, whether and how they can be enforced and how they are administered in the states foreign policies. The field of cybersecurity is a rather opaque area, where many efforts on a general regulation can be identified but fundamental disparities of states opinions are evident. Popular incidents will be discussed and the major issue of attribution will be illustrated. The last area is digital diplomacy, which is a rather new phenomenon too. The states approaches have been researched and the effect on classic diplomacy will be discussed in this part.The internet provides several opportunities to change international law fundamentally, but the west and rising industrial nations represent different point of views. In addition, the influence of civil society via the internet is on a rise, which can lead to a democratization and individualization of international law. However, it is not clear, which outcomes can be expected from those developments.
