Abstract

This paper presents a quantitative information security model using measurable values to describe the security of information systems in supply chain management (SCM) systems, [1]. There are four main drivers in a SCM system: 1) suppliers, 2) manufacturers and inventories, 3) distributors and retailers, and 4) the customers [2]. The security of supply chain management concerns the security of various interactions among these drivers. Each driver requires a different security level relevant to the services it contributes to the overall SCM system. A transition matrix representing the semi-Markov chain model of each driver is developed. Then, a system-wide security for SCM is produced using the transition matrices of each driver to reach a steady state of SCM information security. The model includes nine different levels of attacks presenting several scenarios for an intruder. Comparison of the steadystate security for multi driver model with different levels of attacks is presented. An analysis of the results is then presented and discussed.
