In a period of true transformation and transition for the energy sector, cybersecurity issues become a driver that influences this evolution. To improve, modernize and innovate business services, ensuring the trust and security of the service becomes paramount. The evolution and growth of electric vehicle (EV) charging stations essentially using IoT components is a prime example. With the introduction of these stations and to ensure their secure use, the EDP cybersecurity team invested in a security assessment of previously installed charging stations. While the results of the security assessment did not identify any highly critical issues, some of the models evaluated presented a set of vulnerabilities of medium severity. These results were decisive in educating and increasing the awareness of the key people responsible for managing the charging station services. Moreover, it led to the involvement of the cybersecurity team in the production of technical specifications and necessary security requirements for the renovation and acquisition process for new electric vehicle charging stations. These exercises contributed to the creation of two checklists of security controls: one for IoT components in general, and the other a technically specific list for EV charging stations.
