Policy based management for critical infrastructure protection
Our current societies are fully dependent on large complex critical infrastructures (LCCIs). These LCCIs are large scale distributed systems that are highly interdependent, both physically and in their greater reliance on the information infrastructure, which logically introduce vulnerabilities. Failures, accidents, physical or cyber attacks can provoke major damages which can proliferate by cascading effects and then can severely affect a part or the whole society. This article aims at providing a solution for enhancing dependability and survivability of such systems by developing new models, methodologies and tools. An assessment of vulnerabilities of existing infrastructures is achieved using canonical architectures. Then, we extract abstract security policies that are implemented using a policy based management approach.
