Yokogawa obtains ISASecure EDSA certification for ProSafe-RS safety instrumented system

With the impact of cyber crime and the growing awareness of cyber warfare on the rise globally, companies in the oil, petrochemical, power and other industries are taking greater care when it comes to checking a product’s cyber security features before purchasing it. In response Yokogawa has obtained the ISASecure EDSA certification for the ProSafe-RS safety instrumented system to assure customers of its high reliability.

The ISASecure program has been developed by the ISA Security Compliance Institute (ISCI) with the goal of accelerating the industry-wide improvement of cyber security for industrial automation and control systems (IACS). It achieves this by offering a common industry-recognised set of device and process requirements that drive device security, simplifying procurement for asset owners and device assurance for equipment vendors.

The ISASecure EDSA certification has three elements: communication robustness testing (CRT), functional security assessment (FSA), and software development security assessment (SDSA), and is based on the IEC 62443-4 standard.

Nobuaki Konishi, vice president of the Systems Business Division in Yokogawa’s Industrial Automation Platform Business Headquarters, commented: “Yokogawa is continually striving to provide its customers with optimum security solutions for their control systems by developing highly secure systems and instruments and providing operational support services. Yokogawa aims to strengthen its relationships with customers by demonstrating the reliability of its security solutions.
