Non-Paper on Efforts to Implement Norms of Responsible State Behaviour in Cyberspace, as Agreed in UN Group of Government Expert Reports of 2010, 2013 and 2015. United Kingdom of Great Britain and Northern Ireland, September 2019 Executive summary In this non-paper, the United Kingdom aims to share our approach to the 11 norms of responsible state behaviour that were part of the 2015 Group of Government Experts (GGE) report, and endorsed by the General Assembly. These agreed, voluntary and non-binding norms build on GGE reports in 2010 and 2013 and form a key part of establishing how international law applies in cyberspace, and the United Kingdom is setting out our approach to help encourage transparency, sharing of best practice, and increase mutual understanding. The United Kingdom recognises cyberspace as a fundamental element of securing critical national and international infrastructure and an essential foundation for economic and social activity online. Actual and potential threats posed by activities in cyberspace continue to be of great concern. This paper details some of the practical steps we have taken to implement the voluntary, non-binding norms recommended in previous GGE reports and endorsed by the UN General Assembly in 2010, 2013 and 2015. Whilst we continue to support and reinforce the application of international law in cyberspace, the activity set out in this paper is UK best practice and is not evidence of state practice with regard to the emergence of customary international law. We have included both steps we have taken domestically, and information as to how we have coordinated, cooperated and built capacity internationally.
