Structure of IEC 62443

IEC 62443 is the international reference standard for Industrial Cyber Security of components and systems developed in conformity with ISA/IEC requirements.

What is ISASecure® Certification

ISASecure® is a third-party conformity assessment scheme based on the ISA/IEC 62443 series of standards aimed at Industrial cyber Security certification of IACS systems, such as DCS and SCADA.

ISASecure® Certification benefits

The certification issued by an ISASecure® Accredited Certification Body is the highest global recognition for cyber security-related products and demonstrates that the applicable ISA/IEC 62443 requirements have been met throughout the whole lifecycle.

Functional Safety and Cyber Security: what’s the link between them?

Functional safety is an essential criterion for complex industrial plants. The aim is always to ensure that all the safety systems are operating properly, in line with their SIL. But what happens when a SIL device is also network connected?

What happened to Process Safety?

We now know that when it comes to process safety in constantly connected systems the OT component has an essential role to play. But what are the similarities between these two areas, and how can they be integrated during the lifecycle of a device?

The brand new ICSA Certification by ISASecure for IIoT devices

The ISASecure® program is announcing the new ISASecure® certification offering for industrial internet of things (IIoT) components based on the ISA/IEC 62443 series of standards.

Configuration Management in the field of Safety and Cybersecurity

If you are a manufacturer, and sometimes you have had difficulty with managing product configurations, it is because the regulations for functional security and cyber security expect Configuration Management requirements that are not easy to implement. Find out how to deal with the problem.

IEC 62443 vs. ISO 21434

While IEC 62443 is the standard that dictates best practices for cybersecurity of industrial automation and control systems, ISO 21434 addresses the automotive market. Let us take a look at the common features and differences between the two cybersecurity frameworks.

ACSSA, IEC 62443 Certification for End Users

The most recent of the certifications in the ISA family is ACSSA: Automation and Control Systems Security Assurance Certification. The upcoming opportunity is aimed at End Users to certify the cybersecurity of automation systems in use at their sites based on ISA/IEC 62443 standards.

Solutions for integrating functional safety and cybersecurity into safety components and systems

With the evolution of automation, cyber risks are impacting the functional safety of systems, with AI, IoT, and connectivity requiring integrated management from the very product design phase. System and machine manufacturers subject to European regulations (such as the Machinery Regulation and other related regulations including, for example, the AI Act, Data Act, Cyber Resilience Act, and NIS 2 Directive), whether CE-marked or not, can rely on international standards to ensure holistic compliance. In this article, we look at how safety and security regulations interact with one another and what is most advantageous to do in terms of system certification.

Functional safety, machinery safety and cybersecurity standards applicable in the European and international context

Compliance with the Machinery Regulation: EN 50742 vs. IEC 62443, which approach should be followed?

With EU Machinery Regulation 2023/1230, applicable from January 20, 2027, cybersecurity has become a non-negligible aspect of machinery safety.
