Cyber Week 2017 brings together participants from around the world. This is the 3rd year of the successful collaboration between Singapore and Israel, continuing the joint research of both countries. The aim of the Roundtable is to provide a forum for discussing the academic, commercial, industrial and diplomatic approaches to cybersecurity and to analyze and compare the approaches implemented by our two countries. Specifically, the discussion will be on IT in both financial and governmental organizations, IoT, smart cities, physical security and critical infrastructure. As with our previous meetings, the ultimate aim of this Roundtable is to strengthen the ties between Singapore and Israel and encourage networking between the countries.
