Over the last decade, critical infrastructures have become increasingly complex. They now possess levels of automation which requires the integration of, often, mutually incompatible technologies. In addition, the data sets generated are t, vast and intricate level of interdependency between infrastructures has grown. Any failures, caused by cyber-attacks, have the ability to spread through a system of systems and are a challenge to detect. Therefore, this paper firstly discusses the interdependency challenges facing critical infrastructures; and how it can be used towards creating a support network against cyber-attacks. In much the same way as the human immune system is able to respond to intrusion, our proposed system is able to detect cyber-attacks and share the knowledge with interconnected partners. In order to demonstrate our approach, a simulation framework of 8 critical infrastructures is presented. Furthermore, our big data analysis techniques, used to identify and share threats between infrastructures, are discussed in depth.
