Abstract

Explosives continue to be the primary tactic used by terrorists across the world and given the high security risk faced by mega infrastructure, a systematic security risk assessment framework is proposed in this paper. Classification and rating criteria are established for this framework pertaining to threat/vulnerability and impact/consequence assessment, based on which asset risk rating can be calculated. The proposed risk assessment framework refines the author’s previous work of risk rating criteria and evaluates risks in both qualitative and quantitative ways. Risk ratings are classified both numerically and in color codes for the ease of analysis and application. This framework is validated in a case study of risk assessment of a mega infrastructure facility and can support further risk management and investment policy. A case study of a chemical facility utilizing the risk assessment framework is provided.

摘要

炸药仍然是世界各地恐怖分子使用的主要策略，鉴于大型基础设施面临的高安全风险，本文提出了一个系统的安全风险评估框架。为该框架建立了与威胁/脆弱性和影响/后果评估相关的分类和评级标准，可以根据这些标准计算资产风险评级。拟议的风险评估框架改进了作者之前的风险评级标准工作，并以定性和定量的方式评估风险。为了便于分析和应用，风险评级按数字和颜色代码进行分类。该框架在大型基础设施风险评估的案例研究中得到验证，可以支持进一步的风险管理和投资政策。
