The Basic Act on Cybersecurity was enacted after being approved by the National Assembly in Japan in November 2014. The Payment Services Act was enacted too, and a policy to support FinTech as one of the basic directions of administrative control was recently proposed. The Payment Services Act is intended to achieve a predominating influence over other countries by pushing ahead with public-private cooperation, by grasping international trends, and by providing information concerning FinTech. Japan is concentrating its efforts to create and develop a finance security policy as the management of security and safety has become a key issue in the financial industry. This is in accordance with the environmental changes in the development of ICT technology and the financial market. We need to examine the system and the present conditions of Japan's Cybersecurity, which has been being constructed rapidly as there have been a considerable number of cyber terrors or cases of cyberattacks in comparison with the United States. Korea, also, needs to establish a flexible security policy to guard against security threats and security accidents concerning electronic finance, and to prepare long-term and short-term policies, depending on the changes in security crimes, to increase the efficiency of management and supervision in financial institutions.
