Vendors and service providers often have privileged access to your data and systems—making them a potential weak link. This episode focuses on third-party risk management, including how to evaluate a vendor's security posture before and after engagement. We cover due diligence checklists, contract clauses, security questionnaires, and ongoing monitoring practices. You'll also learn about shared responsibility models and how to manage risks across cloud, SaaS, and supply chain relationships. CISSPs must ensure that third-party access is governed with the same rigor as internal controls.
