The United Nations Group of Governmental Experts on Developments in the Field of Information and Telecommunications in the Context of International Security released a report setting norms for State activity in cyberspace.  The 2015 Group’s mandate was to examine existing and potential threats arising from State usage of Information and Communications Technologies and determine what actions States should take to address them.  According to the group, “voluntary, non-binding norms of responsible State behaviour can reduce risks to international peace, security and stability.”  The very limited nature of the norms proposed by the Group shows how difficult it is to gain international consensus on such issues, particularly when the big powers are expending great resources engaging in cyber espionage and, in some cases, destructive cyber attacks.
