In March 2016，the US State Department issued the “Department of State International Cyberspace Policy Strategy” （referred to as the “Strategy”），the “Strategy” seeks information on actions and activities undertaken to implement the President’s 2011 U.S. International Strategy for Cyberspace （International Strategy），efforts to promote norms of state behavior in cyberspace，alternative concepts for norms promoted by certain other countries，threats facing the United States，tools available to the President to deter malicious actors，and resources required to build international norms. The Strategy notes significant items of progress in implementing the President’s International Strategy and reflects three themes：the applicability of international law；the importance of promoting confidence building measures；and the significant progress the Department has made，working in partnership with other federal departments and agencies，to promote international norms of state behavior in cyberspace，as well as future plans in this area.
