Fine-Grained Keycloak Authorization with ABAC and ReBAC

Keycloak serves as an open-source Identity and Access Management tool providing authentication and basic authorization, yet it faces limitations when handling advanced, fine-grained authorization models such as Attribute-Based Access Control (ABAC) and Relationship-Based Access Control (ReBAC). Permit.io extends Keycloak's capabilities by introducing dynamic policies and fine-grained permissions, supporting both ABAC and ReBAC, which are critical for modern applications requiring context-aware and scalable access control. The integration with Permit.io allows for the creation of complex authorization workflows, such as conditional transfers in banking systems and cascading permissions in file management akin to Google Drive. Through this enhancement, developers can implement dynamic and flexible policies that adapt to real-world requirements, overcoming Keycloak's monolithic architecture and centralized decision-making, which are less suited for distributed systems. This tutorial demonstrates how to configure Keycloak with Permit.io to achieve advanced authorization, ultimately enhancing security, compliance, and user experience.
