Explore a 54-minute conference talk from NDC London where Ashish Jha delves into the challenges of authorization in modern applications. Learn about the limitations of traditional authorization systems like Role-Based Access Control (RBAC) and Attribute-Based Access Control (ABAC), and discover how OpenFGA with its Relationship-Based Access Control (ReBAC) approach offers solutions for fine-grained access management. Understand how ReBAC simplifies complex access control challenges, enhances security posture, and reduces administrative overhead across diverse applications. By the end of this presentation, gain valuable insights into implementing fine-grained authorization in your own applications using OpenFGA, addressing a critical aspect of application security that many engineering teams still struggle with despite advances in authentication.
