Watch a conference talk from Copenhagen Developers Festival exploring the complexities of authorization through relationship-based access control (ReBAC). Dive into advanced authorization concepts that go beyond traditional role-based and attribute-based access control systems. Learn how to implement fine-grained authorization that can handle complex scenarios like friends-of-friends permissions and conditional access rules. Through live demonstrations and practical examples, discover how to define relationships, deploy authorization services, and implement ReBAC in real-world applications. Gain insights into scaling authorization systems effectively while keeping them maintainable and separate from application business logic. Using both human and playful canine-themed examples, explore the nuances of modern authorization challenges and their solutions.
