Bell-LaPadula Model and Markov Chain Model are used for supply chain networks in the previous literature. However, Bell-LaPadula Model only considers the confidentiality aspect of security. Markov Chain Model is used to simulate the dynamics of the security states. In a typical supply chain network, the integrity of business transactions should be as important as confidentiality of those transactions. The purpose of this paper is to apply Clark-Wilson model to the supply chain network integrity. The major concepts of the Clark-Wilson model such as separation of duty, constrained data items, well-formed transactions, and transform procedures are applied to different situations of a supply chain network.
