IEC 62443 Industrial Security Certification

Enhance the cyber resilience of industrial components and systems

Cybersecurity for cyber-Physical Systems

The increasing prevalence of cyber-physical systems has a significant impact on industries worldwide. Across a variety of businesses, from manufacturing and processing plants, to energy suppliers and rail, cyber-physical systems are implemented to enable higher efficiencies, unmatched flexibility and innovative business models. But the new connectivity also translates into a shift in the risk landscape, as cyber-attacks are increasing. Against this backdrop, suppliers and system integrators must optimize the cyber resilience of their components and systems by improving their development, integration and support processes.

Aiming to mitigate risk for industrial communication networks, IEC 62443 provides a structured approach to cybersecurity. The standard was originally developed for the Industrial Automation and Control Systems supply chain, but it has become the leading industrial cybersecurity standard for all types of plants, facilities and systems across many industries. The standard applies to component suppliers, system integrators and asset owners.

Through a set of defined process requirements, the standard ensures that all applicable security aspects are addressed in a structured manner. Security aspects include a systematic approach to cybersecurity throughout the stages of specification, integration, operation, maintenance and decommissioning. Furthermore, the standard foresees that processes are established to facilitate all necessary technical security functions. Adapted to the relevant project scope, it lays the foundations for cybersecurity robustness throughout the product and system lifetime.

IEC 62443 certification can also boost the competitiveness of the supplier and system integrator: A third-party certification demonstrates to asset owners and operators that the purchased component or system is based on a methodized and coherent approach to cybersecurity, in line with industry best practice.

Helping You to Achieve Certification

TÜV SÜD is one of the first companies to provide IEC 62443 certification. Suppliers and system integrators worldwide partner with us to confirm their compliance to applicable process requirements as laid out in the standard.

The standard addresses security processes along the complete supply chain. For product suppliers, TÜV SÜD provides certification services based on IEC 62443-4-1 Secure Product Development Lifecycle. The standard applies to the supplier’s overall security programs, and to the security processes connected to the development of the relevant component and control system.

Corresponding certifications are available to system integrators based on IEC 62443-2-4 Security Program for Service Providers. In this case, the compliance of generic processes, as well as compliance of security processes for a reference architecture or blueprint, can be verified by our experts.

During the certification process, the auditor executes a conformity assessment based on document reviews, interviews and on-site audits. When compliance with standard requirements has been confirmed, the certification concludes with the issuance of a report and the TÜV SÜD certification mark. An annual surveillance audit is required to maintain the validity of the certification. 

Beside the generic process aspects during product development and system integration, the IEC 62443 standard specifies technical security requirements to components and systems. These technical requirements are described in IEC 62443-4-2 and IEC 62443-3-3. The assessment of both process and technical requirements are the basis for the certification of components and systems, respectively.
