The Developer's Guide to RBAC: Part I

This blog series discusses role-based access control (RBAC) and fine-grained authorization (FGA), offering practical guidance for engineers implementing these systems. It highlights that as applications scale, authorization becomes critical for finer access control. The text covers the transition from basic RBAC to more advanced FGA, explaining how authorization is not a priority at first but becomes essential as companies grow and require granular access management. It also delves into the different stages of authorization implementation, from no authorization to resource-based FGA, and discusses role-based authorization basics and challenges. Additionally, it introduces policy languages like OPA and full systems like Zanzibar as potential solutions for implementing FGA.
