Critical infrastructure Kritikus infrastruktúra

Short definition

Critical infrastructure is one of the eight high-risk areas listed in Annex III: an AI system used as a safety component in the management and operation of critical digital infrastructure, road traffic, or the supply of water, gas, heating or electricity is classified as high-risk. In these sectors, disruption can directly endanger human life or health.

This area is listed among the eight high-risk categories in Annex III, in line with Article 6(2). Unlike some of the other areas — biometrics, education, employment, etc. — this point is not broken down into lettered sub-cases according to the source material reviewed for the knowledge base; instead it covers, as a whole, AI used as a safety component of critical infrastructure. The rationale for the classification is clear: if the malfunction or a faulty decision of an AI system can directly endanger the continuity of electricity, water or transport supply, the risk to human life and health can be immediate and wide-reaching. From a business perspective, this category typically affects utility providers and operators of energy or transport infrastructure, not the average SME — for a consultancy or accounting firm this area is generally not relevant, unless it directly develops or supplies an AI solution for operating such infrastructure.

Why this matters for an EU SME

Most Hungarian SMEs are not directly affected by this area — the exception is a company that supplies an AI-based control or monitoring system to a utility, energy or transport operator.
