The utilities sector, including water, sewage, and energy networks amongst other, is considered a critical infrastructure, meaning that the loss, or interruption of them would result in a significant impact of the functioning of the state and/or significant economic and social impacts.
These networks, as well as their associated equipment and personnel are increasingly monitored and controlled by communication technologies. While this digitalisation is highly effective in optimising systems performance and management, it also increases the threat and vulnerability surface to deliberate and intentional (cyber) attacks and unintentional and external hazards and its dependability on the availability of terrestrial networks.
