Cyber Security for Industrial Control System

Abstract

In recent years, sophisticated cyber-attacks that target factories and plants have increased even in production control systems. Due to such increases in threats and changes in the environment, the importance of security measures has become even more urgent. In fact, since2010damage caused by malware infection has increased significantly.
However, this does not mean that blindly introducing security technology will be sufficient. Unlike information systems in general, a stable, real-time operation on a 365 day/24 hour basis is essential considering the sophisticated environment of control systems.
YOKOGAWA group support has taken a holistic approach to security measures in which strategic defense-in-depth concepts are used to effectively evaluate potential risks, consider technical measures and continuously update the system's lifecycle. We believe improvements on a continuous basis are important during operation. Measures are necessary to assess and mitigate the risks identified within the control system and to be better prepared to recover the system in the case of an emergency.
In YOKOGAWA group, by investigating and researching conditions in which security measures are implemented in control systems and the practical use of the latest security technology, we are currently developing effective solutions and optimal measures for a variety of system configurations for different industries and applications. Over the lifecycle of the system, we are committed to providing the best possible solutions and services to ensure high reliability of systems and to provide customer-specific security measures so that stable operation can be maintained.
