Information security is an important issue in supply chain. Information security breaches have serious consequences for companies, such as loss of revenue, reputation, customers, business advantages, and, in the worst-case scenario, bankruptcy. On the other hand, collaboration and integration between different parties is necessary to increase productivity in the supply chain. However, increasing the flow of information increases the risk of information leakage. To mitigate the risk of information security breach in the supply chain we need to have a comprehensive view about information security. This research aims to investigate different dimensions of information security in the supply chain. A review of literature revealed that technological, managerial, organizational, psychological, educational and awareness aspects of information security play important roles in the security of information in supply chain.
