Evaluation of the management of supply chain cybersecurity risks via the application of innovative technologies – The case of Walmart China Blockchain Traceability Platform

Abstract

This study investigates the application of blockchain technology in managing cybersecurity risks within food retail supply chains, focusing on Walmart China's Blockchain Traceability Platform (WCBTP). The aim of the research is to explore potential cybersecurity threats, evaluate the impacts of such threats on supply chain operations and corporate reputation, assess the effectiveness of blockchain technology in mitigating these risks, and propose recommendations for future applications of blockchain technology within the food retail supply chain sector. Using a qualitative research design, the study adopted a case study approach and gathered data through surveys conducted with 20 participants involved in the implementation and management of the WCBTP. The collected data were analysed using thematic analysis to categorize the key themes and insights related to the research objectives. The findings revealed several key cybersecurity risks within Walmart's supply chain, including unauthorized access, data breaches, and system vulnerabilities. The impacts of these threats on supply chain operations included operational disruption, threat to data integrity, and potential financial implications. The study also found that the application of blockchain technology within the WCBTP has been instrumental in managing these risks, with participants noting the benefits of features such as encryption, decentralization, and immutability. Despite the challenges associated with the technical complexity of blockchain and integration issues, several key factors were identified that contributed to the successful implementation of the WCBTP system. These included technical expertise, regular security assessments, stakeholder commitment and effective communication. The study concludes with recommendations for future applications of blockchain technology within food retail supply chains, emphasizing the importance of continuous learning and adaptation, robust security measures, rigorous testing and evaluation, and stakeholder involvement. The research contributes to the growing body of literature on the intersection of supply chain management, cybersecurity, and blockchain technology, providing valuable insights for both academics and practitioners.
