This chapter analyses the concept of risk and resilience for critical infrastructures. The two concepts are tied together: minimizing risk means improving

resilience. In critical infrastructure protection world, assessing risk is very complex due to, among the others, due to interdependency: managing risk is well-established in each infrastructure, but the risk of interconnected infrastructures is still an open problem without a single solution.

Modelling infrastructures and their interdependencies could help in managing risk and also resilience. The proposed approach is called MHR and it is implemented with CISIApro 2.0, an agent-based simulator, which assesses the consequences of events on the reference scenario. We test the proposed approach into a telecommunication scenario, with a hospital ward and a smart factory. The results demonstrate the correctness of this approach that is currently under validation within the EU H2020 RESISTO project. During the project, the system will be integrated into real test-bed provided by various telecommunication providers.
