ITPCM International Commentary July 2015 8 aPPlIcabIlIty of InteRnatIonal humanItaRIan law on Isolated cybeR netwoRk attacks Ameneh Dehshiri Ph.D Candidate in International Law Politics, Human Rights and Sustainability Programme, Sant’Anna School of Advanced Studies, Pisa (Italy) a.deshiri@sssup.it Abstract Information and communication technology changed the way we live, learn and even fight. Information is not only a military supplementary means anymore, but a target itself. Computer network attacks (CNAs) are able to make widespread destruction and human injury in reality. But the question is whether CNAs conducted by one State against another can be the subject of international humanitarian law. This paper seeks to address the legal situation of CNAs which are not operated in the context of a current ongoing combat. Keywords Cyber network attack, International humanitarian law, international armed conflict, armed force, attribution.
