An Economic Optimal Model For Risk Analysis of IT Security
首发时间:2004-10-06
Abstract:A complicated problem faced by organizations is how to balance their potential opportunity costs against the expense of securing their IT infrastructure (preventative defensive measures). The primary goal of this paper is to minimize the costs when we implement preventive defensive measures in a new university campus or enterprise. On the basic assumption that the opportunity costs function are all inverse proportion functions, and with our introduction of 0-1 variables to represent different defensive measure, we constructed an non-linear, restricted optimal model (see formula (10)) to obtain a minimum costs. With the help of the mathematic software LINGO we got the minimum costs and determined the corresponding politic and technical defensive measures.

关于IT安全风险分析的经济模型
摘要:本论文主要针对现在许多机构面临的IT安全措施花费与潜在机会花费间的矛盾,通过引入0-1变量来表示是否采用某IT安全措施,在假设了潜在机会花费为反比例函数基础上,建立了以总花费为目标函数的非线性有约束的最优化模型。并通过LINGO软件解得了此模型的最优解。本论文源于2004美国大学生数学建模竞赛,原文被美国应用数学协会评为国际一等奖。
