Abstract In this paper, the security improvement approaches for process plant instrumentation and process information systems are proposed. By dividing control and information systems into plural zones considering process dynamics under the proposed framework, higher possibility of cyber-attacks detection and operational accident prevention can be attained. Based on this framework, accidents caused by cyber-attacks are evaluated as a form of FTA created from detectability and reachability… Expand
Detection of Cyber-attacks with Zone Dividing and PCA
TLDR
An automatic cyber-attacks detection system using PCA (Principal Component Analysis) is proposed to divide field networks into plural zones and shows that PCA is effective to detect the changes. Expand
