Traditional role-based access control (RBAC) systems just don't cut it for modern, complex applications. In this talk, we'll dive into how Open FGA, an open-source fine-grained authorization solution, tackles these challenges head-on. We'll highlight the shortcomings of RBAC and show how Open FGA uses relationship-based access control (ReBAC) to offer a more flexible and detailed approach. You'll see how this tool can boost security, performance, and access management across various systems. If you’re curious to learn why the future of authorization is fine-grained and how Open FGA is paving the way, you don’t want to miss this session.
