With the advances in Information and Communications Technology (ICT), the ways of cyber attacks have become more sophisticated and diversified. For sustainable peace, it is important to establish international norms on cybersecurity that all UN member states need to develop in a way of a peaceful cyberspace. In this regard, the 2nd OEWG has been established under the auspices of the UN. Thereafter, we have witnessed the conflict of opinions among member states that some say could be considered a new cold-war in the field of cyber security. Due to the conflict, the OEWG has had many struggles in the whole process to achieve consensus. Furthermore, active participation of multi-stakeholders has also complicated the discussions of norms in the OEWG Process. The Jeju Forum brings together experts not only from Korea but also from all over the world to infer views on cyber security and how member States can contribute to the progress of discussion on international cyber security norms.
