Trends and Developments in Security Standards for Secure Social Infrastructure Systems

Tsutomu Yamada Tadashi Kaji, Dr. Info. Toshihiko Nakano, Ph.D. OVERVIEW: Consolidation of standards suitable for control systems is an urgent task that must be accomplished if control system security is to be improved. When it comes to control system security standards, the consolidation of industry standards is happening more quickly, but international standards are also being formulated with four out of the 13 documents of the IEC 62443 series of standards already published. Also, ISASecure EDSA and CSMS certifi cation are standards for certifying conformance with security rules by control systems and control devices. The rapid acquisition of international certifi cations in terms of security is also important from the perspective of strengthening international competitiveness, and the Ministry of Economy, Trade and Industry is implementing a pilot project in order to enable the acquisition of these certifi cations from inside Japan. Hitachi is contributing to standardization activities aimed at the utilization of these standards.
