Certification according to IEC 62443 of Cyber and Industrial Security

Security regarding Industry 4.0 according to the latest certification standards

The danger of cyberattacks is constantly increasing for companies. This makes responsible handling of information more important than ever. After all, information is a precious asset, and its loss or manipulation can cause considerable damage. Networked components or systems are used in many areas today: In medical technology, the automotive industry, railroad technology or the process and automation industry, just as in power plants or wind turbines. Operators, integrators and manufacturers in these and many other industries must therefore today not only consider whether their systems are running securely, but also how they protect their networked systems against hacker attacks.
IEC 62443 is the most important standard for IT security in the industrial sector. It has established itself as an internationally recognized standard for proving compliance in the process and automation industry environment. Due to the lack of standardization specifications, many other industrial sectors are now relying on this standard. This makes IEC 62443 the central certification standard for Industry 4.0.
IEC 62443
also serves as possible proof of compliance with the duty of care in accordance with the German Ordinance on Industrial Safety and Health and the German Product Safety Act.

Scope of application of IEC 62443

IEC 62443 is divided into different sub-standards and addresses the logical levels of organization/processes, system and components as well as process-related and functional requirements. IEC 62443 thus normatively maps the entire industrial spectrum in accordance with the requirements of operators, integrators and manufacturers. The classic business structures (TIC testing, inspection, certification) are taken into account in the context of audits of processes and systems, as are measures for product testing or certification of components. IEC 62443 is thus a central tool geared to IT security for industrial communication networks. With its clearly defined process models and best-practice recommendations, the standard helps to approach this complex topic in a manageable way.

IEC 62443 Security Level: Structure of the standard

IEC 62443 Security Level: Structure of the standard
The series of standards currently comprises eleven sub-standards. The standard is divided into four coherent sections, the so-called Security Levels (SL). These in turn contain documents on individual key topics. The various levels indicate the resistance to different classes of attackers. The standard emphasizes that the levels are to be evaluated per technical requirement and are not suitable for the general classification of products.

This certification standard allows the fulfillment of due diligence to be demonstrated as well as laying the foundation for proof of conformity at an early stage.

FAQ - We have the answers

Why certification according to IEC 62443?

Certification according to IEC 62443 analyzes and evaluates safety concepts and measures. It proves that the certified company works according to the 'state of the art' and fulfills its legal duties of care - important prerequisites for minimizing liability risks. In addition, components can be placed on the market safely in accordance with the Product Safety Act (ProdSichG). And last but not least, companies can protect their employees in this way in accordance with the Industrial Safety Ordinance.

Hackers and cybercriminals do not stop at industrial plants. If they discover a weak point, they can sometimes put entire industrial plants out of operation. Particularly in the area of critical infrastructures, this can have dramatic consequences, such as lasting supply bottlenecks.

IEC 62443 provides you with the best possible protection against cyber attacks and improves the overall security of your production. The international standard provides you with a guideline of criteria and security requirements with which you can increase the integrity, availability and confidentiality of your components and systems.

What is the goal of the IEC 62443 series of standards?

The objective is to provide standards, procedures, technical reports and additional information that define processes for the safe implementation of IACS. This is intended to provide guidance to all those responsible for the design, implementation, management, manufacture and operation of IACS. It is also intended to address users, integrators, manufacturers and vendors.
