Yokogawa will leverage this certification to accelerate its efforts to enhance the cybersecurity of its customers’ plant operations.

ProSafe-RS safety instrumented system

Yokogawa obtains ISASecure CSA Level 1 certification from the ISA Security Compliance Institute*1 (ISCI) for its ProSafe-RS safety instrumented system, a product in its OpreX Control and Safety System family. The company maintains this is the first time a safety instrumented system has obtained this certification.

Released in February 2005, the ProSafe-RS safety instrumented system helps to prevent accidents by detecting abnormal conditions in plant operations and initiating emergency actions such as a plant shutdown. Unlike conventional safety instrumented systems and distributed control systems, which are regarded as having different roles and functions and operate separately, the operation of ProSafe-RS and the CENTUM integrated control system can be fully integrated.

Yokogawa’s ProSafe-RS safety instrumented system is certified for use in safety integrity level 3 (SIL3) applications. With regards to cybersecurity, it has held ISASecure EDSA certification since 2013. Replacing this certification program, ISASecure CSA certifies compliance with the IEC62443-4-2 and IEC62443-4-1 international standards pertaining to control device security. Receipt of this certification indicates that a product has been recognized by a third party as having security controls that conform to these international standards. Yokogawa also plans to obtain ISASecure CSA certification for the ProSafe-RS Lite SIL2 safety instrumented system, which was released in January of this year.

Developed by the ISA Security Compliance Institute (ISCI), the ISASecure CSA certification program focuses on the security of embedded devices and related components (software applications, host devices, and network devices). Yokogawa will leverage this new certification to accelerate its efforts to enhance the cybersecurity of its customers’ plant operations. In August 2017, a malware attack on a safety instrumented system was reported and led to a call for enhanced cyber security measures to deal with the threat to these systems, which play a pivotal role in ensuring plant safety.
