CARVER+Shock: Food Defense Software Tool

摘要

The CARVER acronym represents the steps in a threat analysis exercise: Criticality, Accessibility, Recognizability, Vulnerability, Effect, and Recuperability. The CARVER+Shock software was developed as an easy-to-use tool for defending food production against malevolent attacks. Shock is added to incorporate the intangible focus of a terrorist in frightening a targeted group. The software uses the CARVER targeting methodology to identify components in a production process that are best suited for security improvements and recommends mitigative steps to improve defense. The food defense software is described and demonstrated on hypothetical yogurt and apple product food-production processes. Two of the algorithms used to generate scores in the analysis are presented and the assumptions listed. The calculated scores are compared and discussed. Version 1.0 of the software is available free from the U.S. Food and Drug Administration website. Software upgrades for pre-harvest agriculture and for retail/restaurants analyses are being developed for release in early 2009.
