Introduction
The CI (Critical Infrastructure) acronym refers to a complex, interconnected network of physical and logical components composing systems that are essential for the functioning of our daily lives. These systems provide vital services and support several sectors, including energy, water supply, transportation, communication, healthcare, emergency, and finance. Disruption in any of these services, even if isolated but persistent, can cause considerable damage, which gives this threat a very high-risk level. Different countries assume slightly different definitions, classifications and approaches. But all share the same concern, even if adopting more solo approach strategies than desired, as the impact of incidents in this context can affect several countries when there are shared distribution chains.
