A comparative analysis of security risk assessment methodologies for the chemical industry

none4noAn overview and a comparative analysis of existing methodologies adopted in the US and in Europe for the assessment of risks posed by intentional attacks against industrial sites, and more specifically chemical facilities where relevant quantities of hazardous substances are stored or processed, are given. Two case studies were analyzed by the ANSI/API RP 780 and the VAM-CF methodologies. The results show that the VAM-CF methodology resulted to be more conservative with respect to the API methodology for low-risk scenarios. The API methodology resulted more suitable for practical application, in particular for analysts having limited experience. © 2018openAnita Matteini; Francesca Argenti; Ernesto Salzano; Valerio CozzaniAnita Matteini; Francesca Argenti; Ernesto Salzano; Valerio Cozzan
