Matthias Reinwarth and Dr. Phillip Messerschmidt delve into the complexities of Cyber Supply Chain Risk Management (C-SCRM). They discuss the importance of understanding and mitigating risks that arise from external suppliers and the interconnected nature of modern supply chains. The conversation highlights the critical role of Identity and Access Management (IAM) in managing these risks, particularly in the context of federated identities and the challenges that arise from relying on third-party controls.
