Chemical facility security has become a much debated topic since the 9/11 attacks. There are many parallels between security vulnerability and safety analyses of engineered systems. A security vulnerability analysis of a medium-sized chemical facility was conducted using a methodology similar to that developed by Sandia National Laboratories. The facility was evaluated in terms of its susceptibility to adversarial actions from outsiders and insiders, which could lead to the release of a hazardous chemical. Focus was placed on the most critical aspects of the facility, but all areas that could be in danger were addressed. A quasi-probabilistic risk assessment methodology was followed to allow proper ranking of various scenarios. Special attempt was made to identify a comprehensive list of scenarios and to characterize them in terms of threat source, likelihood of attack, features in place for detection and deterrence and extent of consequences of the malicious act. This paper concentrates on the application of the methodology and lessons learned in terms of strengths and weaknesses.
