Abstract
Critical infrastructure assets contribute to the economy and society as a whole. Their impact on the security, economy and health sector are extremely vital. However, their increasing complexity has led to the creation of direct and indirect interdependent connections amongst the infrastructure groupings. In this paper, the development of a distributed support system is presented. The system employs behaviour analysis techniques to support interconnected infrastructures and distribute security advice throughout a distributed system of systems. The approach put forward is tested through a statistical analysis method approach in order to investigate the cascading failure effect whilst taking in to count the independent variables.
