Enhancing transport security: Characterization and identification of the main security challenges in 5 transport subsectors

In a context of growing attention towards transport security and critical infrastructure protection in Europe, this paper aims to provide a concise overview of security issues which could affect the 5 transport sub-sectors listed by Council Directive 2008/114/EC. Transport system´s supply chains are to identify their key assets, functions and operators and interactions between components. The aim is to suggest a useful approach to understand the different security challenges along the supply chain and to support the future development of tailored protection strategies, especially in the time of Critical Infrastructure strategy evaluation.
