Fine-grained Authorization

1 post · May 2024

What this trail covers

Vercel's platform supports implementing fine-grained authorization models within applications, leveraging solutions like OpenFGA and Okta FGA. This enables relationship-based access control (ReBAC) for more flexible authorization than traditional RBAC, allowing developers to define complex relationships between users, groups, and resources. This capability is integrated into the development workflow, particularly within Next.js applications, by introducing a Data Access Layer (DAL) that centralizes authentication and authorization checks. The DAL acts as an intermediary between application logic and persistent storage, ensuring users are authenticated, authorized, and data is fetched or updated securely. The post details how to integrate OpenFGA's DSL for defining authorization models and using its SDK to perform authorization checks within the DAL.

  1. Securing data in your Next.js app with Okta and OpenFGAThis post introduces the concept of a Data Access Layer (DAL) for centralizing authentication and authorization checks in Next.js applications. It demonstrates how to implement fine-grained authorization using OpenFGA (or Okta FGA) and its DSL for defining authorization models and relationships. The post provides code examples for setting up the OpenFGA client and performing authorization checks within the DAL, enabling relationship-based access control (ReBAC) beyond traditional RBAC.
