The energy industry faces unique cybersecurity challenges because of the large supply chain and the interconnection of heterogeneous, complex, distributed systems. The digitalization of Operational Technology (OT) systems and the interconnection to traditional IT increase the complexity of the infrastructure, expanding the attack surface to more threat actors.

Distributed monitoring and supervising devices, such as smart meters and smart breakers, are located in unsafe environments and exposed to physical and hardware attacks that could have serious impact on the whole infrastructure.
