The CRA sets out specific requirements that must be taken into account during product development. The principles of security by design and security by default apply. The required risk assessment ensures that the CRA requirements are met and that possible threats are neither underestimated nor overestimated, thus avoiding the incorrect planning of measures.
Processes (e.g. IEC 62443) and the documentation of process results ensure compliance with the CRA. Depending on the product category, the security can be verified by oneself or a notified body needs to be involved.
CRA defines the categories “Standard/Basic Products”, “Important Products” and “Critical Products”. The product categories do not influence the required activities (processes), but only the conformity assessment procedures (provision of evidence).
Cybersecurity must be guaranteed for the expected lifetime of the product, but at least for 5 years. This is done by regular and effective cybersecurity tests (e.g. penetration tests). This also includes updating the risk assessment. Weak points in the product must be reported immediately and eliminated by means of software updates. All these activities must be planned and documented. Here, too, processes ensure that this is done.
Various aspects of the CRA are still unclear. There are no harmonized standards yet and no notified bodies. The latter should be available in 2026.
Products that are already on the market are not covered by the CRA as long as they are not significantly modified. Guidelines for defining a significant change have not yet been drawn up. However, the CRA provides indications of what could be a significant change. For example, new features or feature updates that could have an impact on cybersecurity risk are to be considered significant changes. It follows that the change must be checked and evaluated, which means that at least a risk assessment of the product must be carried out.
