Abstract

Acts of interference against process facilities may lead to major accidents in case of a successful attack. Although several security risk assessment (SRA) methodologies are available to provide guidance to operators of the chemical and process industry in the assessment and management of security risks, they lead to a qualitative or a semi-quantitative assessment. The present contribution presents a quantitative analysis tool aimed at supporting the probabilistic assessment of industrial facilities vulnerability to external attacks, supported by a Bayesian Network (BN). The adoption of BN allowed to represent the interactions among attack impact vectors, the protection systems and the process units, which determine the final outcomes of an attack. Possible practical applications in the perspective of conducting SRA quantitatively were presented; on the other hand, the main limitations were discussed and future research needs identified. |
