Rationale and development of a Security Assurance Index with application toward the development of a World Risk Index

摘要

Assurance categories were previously developed to support the Department of Homeland Security's efforts in the mitigation of Cyber Control System events. Defined according to the risk of life and economic loss, the minimum range is designated by policy; whereas, the maximum limit seems to be constrained only by limits and interdependencies of the event. Use of this life/assets scale has proven to be helpful in managing risk due to the scales ease in use, communication, and understanding. Suggestions have been made that this scale could be applied to all events of terror, disaster, and calamity of an international scale, with equally good results. This paper will present the history of some existing scales of disaster and assurance, the rationale behind the development of the original Security Assurance Index, and our proposed scale of disaster and calamity as a World Risk Index.
