Security Technologies, Usage and Guidelines in SCADA System Networks
Mai Kiuchi,Yoshizumi Serizawa 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
The use of off-the-shelf IT systems in SCADA systems has increased, resulting in higher usability at a lower cost. This has introduced a higher risk from cyber threats. As many SCADA systems play an important role in infra-structure and industrial systems, it is important to maintain reliability and security. However, applying cyber security measures should not interfere with the functionality of the SCADA system. We used a model SCADA system to assess various security measures deployed in the system. In addition, standards and guidelines will become more important for selecting appropriate security.
Study on Delay Time Evaluation for Carrier Relay System Using IP Communications Technology
Doi, Hiroki,Shioyama, Takuto,Fujikawa, Fuyuki,Serizawa, Yoshizumi The Korean Institute of Electrical Engineers 2013 The Journal of International Council on Electrical Vol.3 No.3
The transmission devices of carrier relay system use exclusive transmission devices and do not use IP (Internet Protocol) communications technology. But the IP communications technology has made remarkable advances recently and is used in the world. If Internet technology can adapt for the transmission device of carrier relay system, electric power company can construct the integration network for power protection and control system which includes carrier relay system. In this report, we will assume the network configuration using Internet technology for the transmission devices of a carrier relay system and show that the transmission devices using Internet technology satisfy the carrier relay specification, such as delay time and differential delay time.
