Abstract—Global strife and the perception of injustice create suitable conditions for terrorists, as well for saboteurs, thieves and vandals, to recruit and raise support.
In addition, as Countries modernize, they increasingly depend on technologies, and the interconnections among systems, such as energy distribution, telecommunication and transportation systems, are becoming increasingly strong. Such networks of Critical Infrastructures (CIs) represent, in many cases, the targets to the above cited adversaries.
Taking into account the above considerations in this paper, the “second step” results of a project aiming to design an effective tool for risk analysis are described, focusing on the problem of evaluating the global risk of ground transportation infrastructures, such as highways and railways, after the introduction of some suitable protections in some the elements making it up.
The paper is organized as follows: after a brief literature review, the main characteristics of the considered tool architecture are recalled. After this brief introduction the new modules are described, focusing on the enhancements they provide to the whole architecture. Finally, a case study is described with the aim of showing the capabilities of the proposed architecture.
