Inter-dependency assessment in the ICT-PS network: the MIA project results

Inter-dependency evaluation through quantitative approaches is one of the open challenges in Critical Infrastructure Protection. The incapability to conduct appropriate networks inter-dependencies measurements undermines the possibility that the Critical Infrastructures protection programs can correctly assign resources and efforts for mitigation solutions targeted to the most important risks. This paper describes the approach and metrics used in the "Methodology for Interdependencies Assessment" EU Project to asses inter-dependencies in ICT and Power System networks. The major project finding, metrics applicability results and scalability issues are described in the paper.
