HIMA HIMax safety controller

HIMA’s HIMax safety controller has been awarded a cybersecurity certificate from TÜV Rheinland. The test agency certified the processor and the communications module in accordance with international standards IEC 62443-4-1, IEC 62443-4-2 and ISASecure EDSA 2.0.0. The certificate is based on stringent testing and evaluation of all requirements regarding IT security over the entire lifetime of the safety controller, and it says that the HIMax fulfils the requirements of security level SL 1.

Nowadays, plant operation is only reliable when plant operators systematically implement cybersecurity measures in addition to functional safety. The key normative basis for this is the international standard IEC 62443, ‘IT security for industrial automation and control systems’, which specifies separate network levels with defined conduits. The newly developed cybersecurity certificate from TÜV Rheinland also conforms to this standard.

TÜV Rheinland tests controllers in accordance with the IEC 62443 standard (Part 4-1, ‘Secure Product Development Lifecycle Requirements’, and Part 4-2, ‘Technical security requirements for IACS components’).

HIMA additionally received the Embedded Device Security Assurance (EDSA) certificate from ISASecure. ISASecure certification (ISASecure EDSA 2.0.0 – Level 1) is based on a test methodology derived from the IEC 62443 standard. Along with these two certificates, the cybersecurity of the HIMax controller is documented by an Achilles Level 1 certificate issued by the independent Canadian industrial security specialist Wurldtech.
