Cyber-attacks are on the rise worldwide and are growing ever more sophisticated. In recent years, many attacks have targeted industrial control devices, resulting in lost production and the theft of information.

In August 2017, a malware attack on a safety instrumented system was reported, and this has led to a call for enhanced cybersecurity measures to deal with the threat to these systems, which play a pivotal role in ensuring plant safety.

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

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).

The ISCI’s members come mainly from the International Society of Automation, and the principal activity of this organization is the promotion of security certification for industrial control systems and control devices.

The ISASecure CSA certification program was launched in August 2019, replacing the ISASecure EDSA certification program. It complies with the International Electrotechnical Commission’s IEC 62443-4-2 and IEC 62443-4-1 international standards for security in control devices.
