We've created an openly accessible analytical app with Cube, which can be accessed by anyone without authentication checks being enabled. We then added authentication using signed and encrypted JSON Web Tokens (JWTs) to secure the API. Next, we implemented authorization with JWT claims to control access to data based on users' roles. Finally, we integrated the web application with Auth0 as an external authentication provider, which identifies all users and generates JWTs for them, ensuring only logged-in users can access the app and perform queries to Cube. With these measures in place, our app now implements IAAA (identification, authentication, authorization, accountability), making it a secure multi-tenant analytics platform.
