Yokogawa’s Security Lifecycle

As control system technologies are constantly evolving, security risks such as attack techniques are also evolving.

For example, attacks targeting specific industries and control systems have been increasingly reported. This means the one time deployment of security controls is not enough to control security risks. Thus, a periodic review of controls is required. It is called a security lifecycle of control systems. According to this idea, Yokogawa supports customers in securing their control systems.

Defense in depth

Yokogawa recommends a comprehensive approach based on the defense in depth strategy. This not only means deploying multiple technical controls, but also more important things, such as ensuring safety and performance of the control systems that is required for production activity, and maintaining control system health. They are followed by implementing technical, operational and managerial controls for cyber security.
