Vulnerability and Resilience Assessment of Infrastructures and Networks: Concepts and Methodologies
Résumé
The vulnerability of infrastructures and networks is being increasingly studied especially regarding combined natural/technical risks or/and intentional threats, in response to recent catastrophic events and their global consequences. Some methodologies have been recently developed coming from fields as diverse as: technological risk analysis, resilience engineering and global security approaches, but also logic system security, system of system vulnerability, etc. All these methods are adapted to specific contexts, and in general cases, a combination of them is needed. This is why generic conceptual studies of the vulnerabilities and resilience of systems have been developed. This chapter deals with these generic concepts and systemic approaches concerning risk, vulnerability and resilience concepts, presents paradigms as consequences of those and some recent methodologies for resilience analysis and assessment. Finally, the conclusion is dedicated to the new challenges and fields to be studied in terms of system resilience.
