Authorization models need to be as flexible and dynamic as the environments they protect. In this session, I’ll take you on an adventure through the world of Relationship-Based Access Control (ReBAC) with OpenFGA, an open-source authorization system built for high performance and flexibility. I'll demonstrate Airport Quest; a fun, interactive scenario to guide you through the limitations of traditional models like Role-Based and Attribute-Based Access Control. Then, I’ll show you how we can improve Airport Quest by incorporating OpenFGA. OpenFGA empowers developers to manage fine-grained, dynamic access control by leveraging real-world relationships between users and objects. Expect a unique and engaging experience that combines practical demos with a touch of adventure as I show how to implement ReBAC in a .NET environment and make authorization smarter, not harder.
