Role-based access control (RBAC) is essential for implementing a secure and effective internal developer platform, as it enhances the developer experience by clearly defining permissible actions and views based on user roles. The Port platform offers a no-code, flexible approach to RBAC, integrating with single sign-on (SSO) providers to inherit organizational structures and allowing administrators to define granular access rules. This includes setting permissions for reading, writing, and executing actions within the platform, with self-service options tailored to various user roles and proficiency levels. Port's implementation of RBAC also includes an audit log feature, which records all events within the developer portal, providing transparency and security by tracking interactions and modifications.
