Cyberwarfare in international law

With the development of technology, important changes have shown itself in the law of war, as in many areas. Satellite and communication systems, which are indispensable for daily social life, hospital, traffic lights, natural gas, water, electricity, etc. The inclusion of infrastructure systems and service areas such as trains and flights, and remotely controlled vehicle systems such as unmanned aerial vehicles into the cyber space has brought along the danger that these systems can be sabotaged from the computer in case of cyber warfare. This process in particular required a reinterpretation the use of force and the law of armed conflicts. As a requirement of the age, the realization of the main fields of activity of nation states in the cyber environment has inevitably caused the abuse of these systems within the scope of the use of force and has revealed the international cyber warfare law as a new field. For this reason, traditional use of force concepts, self defense, responsibility of the state and the law of armed conflict should be re-evaluated within the framework of international cyber warfare law. In context of this thesis; it is aimed to reinterpret the concepts of jus ad bellum and jus in bello within the scope of international cyber warfare law, as well as related issues of international law that can be applied in cyberspace.
