IEC 62443 standards in IIoT: Why is it so important?

29 May 2024 at 15:44

The IEC 62443 series of international standards ensure the cybersecurity of industrial automation systems, also known as Industrial Control Systems (ICS). As an industrial player, it's crucial to use secure solutions. Ewon Cosy+ has been assessed against IEC 62443-4-2 criteria by NVISO, a globally recognized cybersecurity expert. This confirms once again that Ewon is the ideal partner to enhance the security of your industrial plant.

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. These series of standards describes the basic requirements and processes for implementing and maintaining cybersecurity in IIoT. 

Whether you're a machine builder, a systems integrator or a plant operator, you know that assessed solutions can help strengthen the security of your network. Each of these stakeholders follows a risk-based approach at his own level to prevent and manage the security risks specific to its activities.

Why is IEC 62443 crucial in the industry?

What seems obvious today is that for any industrial player, it is no longer possible to ensure the continuity of their business without industrial connectivity. 

IIoT also has a major impact in terms of productivity and cost reduction, and doing without represents a major risk to competitiveness. But 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 management. This holistic approach is one of the strengths of this standard.

These standards set out the guidelines to be followed by all industrial players:
Manufacturers must provide maximum protection for their products.
Integrators and operators guarantee safe interactions and processes.

To ensure the effectiveness of measures, all links in the chain must of course 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, leading to a comprehensive security plan.

Step 2: Setting up appropriate processes

Ensure that appropriate processes are in place and that staff are trained in security requirements. Never forget that safety is not just about technology. It also involves appropriate processes and qualified personnel.

Step 3: Ensuring constant evolution

It's clear that today's threats are not tomorrow's threats. It is therefore essential that protection systems evolve over time. Continuous monitoring, maintenance and updating are essential.
