Industry 4.0: Focusing on industrial security with IEC 62443

With the help of IEC 62443 you – as an operator, integrator or manufacturer of industrial automation systems – can objectively demonstrate that cybersecurity is a top priority in your company and that you effectively implement the current IT security standards. The Cyber Security Act of the EU passed on 29.06.2019 recommends a corresponding voluntary cyber security certification, whereby the EU Commission will regularly check a possible obligation. We support you in this with numerous services for the successful implementation of and certification according to IEC 62443.

IEC 62443: Holistic approach for industrial security in the field of production and automation

The IEC 62443 standard has now established itself as an internationally recognized standard for security in the process and automation industry environment. Furthermore, its field of application also covers all other industrial sectors and critical infrastructures (KRITIS).

Standard focus: Cybersecurity of “Industrial Automation and Control Systems”

The standard focuses on the cybersecurity of "Industrial Automation and Control Systems" (IACS), which are the decisive aspects for the security of the entire production plant. The term IACS therefore covers all parts, such as systems, components and processes, which are required for the safe and reliable operation of an automation solution. In addition, IEC 62443 also takes into account the organizational processes behind their construction and operation. 

Why is a certification according to IEC 62443 useful?

Hackers and Internet criminals do not spare industrial plants. If they discover a vulnerability, they can sometimes put entire industrial plants out of operation. In the area of critical infrastructures in particular, this sometimes has dramatic consequences, such as supply bottlenecks that have a lasting effect.

With IEC 62443 you can protect yourself in the best possible way against cyber attacks and improve the general security of your production. The international standard provides you with a guideline to the criteria and security requirements with which you can increase the integrity, availability and confidentiality of your components and systems.
