Economic and Sensitivity Analysis of Information Security Investment

摘要：

The paper derives fuzzy economic models to evaluate economic feasibility of information security investment, and normalized sensitivity analysis is performed to exploit the fact that these models are fully known and not a black box. Fuzzy Net Present Value (NPV), and discounted Return on Investment (dRoI) models are proposed for the execution of costbenefit analysis. The performances of the proposed fuzzy economic models are verified by considering their application to a practical illustration. These investigations not only confirm that the results of the fuzzy economic models are consistent with those of the conventional crisp models, but also demonstrate that the proposed models are more flexible, intelligent and computationally efficient compared to the traditional crisp engineering economics.
