Abstract

Increasing concerns about the security and survivability of critical infrastructures have led to the emerging of vulnerability concept as a study field in parallel with the risk paradigm. But vulnerability is still an ill defined concept and the method for analysis and assessment is hence not sufficiently available. What is vulnerability? Why it matters? How vulnerability approach works in accordance or complementarily with risk approach? How to measure it? These are questions embraced in the present work.

The complexity of critical infrastructure systems and its related security issues calls for a holistic approach. Various modeling techniques of complex systems are in rapid development, and facilitate vulnerability assessment and management with good theoretical and practical foundation. The work done in this thesis is mainly oriented towards the following: after reviewing the studies on critical infrastructure and vulnerability study, to come up with a methodological framework of Hierarchical Holographic Vulnerability Assessment.

The central idea is Hierarchical Holographic Modeling (HHM), which is used in stepwise approach within the framework of parsing the vulnerability concept, hazards and accident scenarios identification, and vulnerability management etc. The proposed framework can served as generic vulnerability assessment platform, and leaves the potential to be further developed with application cases.
