IEC 62443 standard in the IIoT:

What is IEC 62443?

IEC 62443 offers a global approach to protecting industrial systems against cyber threats. It complements ISO 27001, which focuses primarily on IT security, which is of course also mandatory for IIoT cybersecurity. This series of standards describes the basic requirements and processes for implementing and maintaining cybersecurity in the IIoT.

Whether you are a machine builder, a system integrator or a plant operator, you know that evaluated solutions can help strengthen the security of your network. Each of these players takes a risk-based approach at their level to prevent and manage the security risks specific to their activities.

Why is IEC 62443 so important for industry?

It is clear that it is no longer possible for any industrial player today to ensure the continuity of their business without industrial connectivity.

The IIoT also has a major impact on productivity and cost reduction, and not doing so poses a major risk to competitiveness. However, it goes without saying that the chosen solution must meet strict cybersecurity criteria.

IEC 62443 ensures the safe operation of industrial automation systems, from machine design to production line control. This holistic approach is one of the strengths of this standard.

This standard defines the guidelines to be followed by all industrial players:

• Manufacturers must ensure maximum protection of their products.
• Integrators and operators must ensure safe interactions and processes.

Of course, to ensure the effectiveness of the measures, all links in the chain must meet the same high standards.

How do you integrate IEC 62443?

Step 1: Risk identification
An in-depth threat analysis determines the requirements for systems and components and leads to a comprehensive security plan.

Step 2: Set up suitable processes
Ensure that appropriate processes are in place and employees are trained in security requirements. Never forget that security is not just a question of technology. It is also about suitable processes and qualified personnel.

Step 3: Ensure continuous development
It is clear that the threats of today are not the threats of tomorrow. It is therefore important that protection systems evolve over time. Continuous monitoring, maintenance and updating are essential.
