Critical infrastructures: a comparison of definitions

摘要

The aim of this paper is to identify common characteristics of critical infrastructure that is informed by national, standards and academic sources. A fundamental understanding of the interconnectivity and dependencies and interdependencies that exist within critical infrastructure is essential to ensure international protection. In working towards an international definition of critical infrastructure there will need to be cooperation and collaboration between nations. The paper determines, through analysis, the foundation of critical infrastructure and its complexity given national and international links to support collective understanding. The paper highlights the potential harm that can be caused if critical infrastructure links are not fully understood. A definition of critical infrastructure is proposed, and future work suggested.
