Critical Infrastructure Protection, Modelling and Management: An Australian Commercial Case Study

This research extends upon the previous work of pye and Warren (2005) and presents a refinement of the previously proposed critical infrastructure model to enhance further our understanding and appreciation of where the likely inter-play and existence of dependency relationships between infrastructures coexist. These associations are presented as a number of linkages that exist within each sector of Australia's critical infrastructure, which is then extended further to the modelling of dependency inter-relationships that exist between critical infrastructures utilising Petri Nets. The recognition and identification of such reliance relationships between critical infrastructures is necessary to allow both infrastructure owners and the government to identify and effectively manage and maintain the security, stability and availability of their particular critical infrastructure against potential scenario driven effects. These issues are reflected within a case study as modelled using the Petri Net approach to encapsulate the issues of reliance relationships by drawing upon an Australian commercial case study.
