Abstract
Information sharing is a key element in any Supply Chain Management (SCM) system and is critical for improving supply chain performance and enhancing the competitive advantage of an organization. However, many organizations are reluctant to share information with their supply chain partners because of lack of trust, the fear of information leakage and security attacks from malicious individuals or groups. Through an extensive literature review, this paper examines the possible security threats/attacks in a SCM system. Then the key technologies and techniques for securing the information shared in SCM are identified with the goal of improving organizations' capabilities in sharing secure information.
