Abstract(s)
Today’s critical infrastructures (CIs) depend on information and communication technologies (ICTs) to deliver their services with the required level of quality and availability. ICT security plays a major role in CI protection and risk prevention for single and also for interconnected CIs were cascading effects might occur because of the interdependencies that exist among different CIs. This work addresses the problem of ICT security in interconnected CIs. Trust and reputation management using the policy-based management paradigm is the proposed solution to be applied at the CI interconnection points for information exchange. The proposed solution is being applied to the Security Mediation Gateway being developed in the scope of the European FP7 MICIE project, to allow information exchange among interconnected CIs.
