Contents I. Introduction
Critical Infrastructure is an extreme way to identify facilities that make easier our way of life. For example, when we flip a switch, we expect light. When we pick up a phone, we expect a dial tone. When we turn a tap, we expect drinkable water [1]. That kind of services are only a few of the critical infrastructure services that we tend to take for granted and we notice them only when, for some reason, service is disrupted. Critical infrastructures can be defined as a set of systems and assets, whether physical or virtual, which in the event of a failure, would cause great impact on the physical or economic security of the people, or in the good functioning of a Government [1].
