The IEC 62443 international security standard covers all layers (operators, system integrators, and equipment suppliers) engaged in the manufacturing of industrial control systems and all players (enterprises and organizations involved in industry and public infrastructure). Within this standard, endpoint devices such as sensors and programmable logic controllers (PLCs) must be certified under IEC 62443-4. The certification process imposes a significant burden on developers. It requires them to interpret the difficult standard, to prepare the software and documentation required for certification, and to execute a procedure that requires specialized expertise.
To help developers overcome these certification challenges, Renesas is developing an industrial security solution that supports IEC 62443-4. Together with deliverables through the activities in Civil Infrastructure Platform (CIP) Project, the Renesas RZ/G Linux Platform security solution will enable users to reduce the time required for obtaining IEC 62443-4-2 certification by as much as six months, claims the company. Renesas is working through the newly established CIP Security Working Group to develop secure open source software (OSS) that complies with IEC 62443-4-2, to establish guidelines for implementing security functions and applications using OSS, and to help create the testing procedures and testing environments necessary for obtaining IEC 62443-4-2 certification.
