The concept of “Smart Cities” interconnects different operators and service in order to improve functionalities and the quality of life of citizens. For that purpose, Smart Cities rely on an Information and Communication Technology (ICT) architecture to retrieve, process and exchange data.


Operators in Smart Cities have different domains of activity, such as the Energy, public transport, public safety. They deploy and operate “cyber-physical systems”, that are data-controlled equipment which interact with the physical world. They collaborate and exchange data under several schemes, depending on the level of maturity of the Smart City.

Yet, these operators are not experts in cyber security. ENISA supports sectors such as Intelligent Public Transport and Smart Airports.
