Security Architects and Lead Developers
Designing the authentication and authorization layer for a new set of public-facing APIs
Use cases
About
The API Security Architect mind map provides a technical framework for securing application programming interfaces, specifically focusing on the OAuth 2.0 protocol and OpenID Connect (OIDC) standards. This API Security Architect template serves as a comprehensive API Security Architect cheat sheet for developers and security engineers, mapping out the critical interactions between the 'API security domain' components, including users, developers, and administrators. The structure details the 'Authorization Flow' through a concrete banking scenario, illustrating how third-party applications request access to sensitive data via authentication servers. By covering the 'Extension of Oauth 2.0', the template explains how OIDC addresses authentication gaps and enables Single Sign-On (SSO) capabilities. This 9-node diagram acts as a foundational reference for designing secure digital ecosystems where developer portals distribute keys and manage API access control.

How to use this template
Step 1
Import the security framework
Download and open the .xmind file to view the pre-structured API security domain and authorization flow branches.
Step 2
Map your specific components
Replace the generic banking scenario nodes with your own application's specific authentication server URLs and redirect logic.
Step 3
Define access control roles
Customize the developer portal and admin nodes to reflect your organization's specific API key management and permission policies.
Frequently asked questions
This template includes a breakdown of the API security domain, the step-by-step OAuth Authorization Flow, and the integration of OpenID Connect. It covers the roles of developers, users, and admins, as well as the technical process of key distribution and authentication server redirects.
It uses a practical scenario where a user (Joe) attempts to access banking information through a third-party app. The template maps the request from the app to the bank's authentication server and the subsequent browser redirect for user login.
Yes, the template specifically addresses how OpenID Connect functions as an extension of OAuth 2.0 to fill authentication gaps and better enable Single Sign-On (SSO) across different applications.
Absolutely. You can expand the 'API security domain' nodes to include specific gateway configurations, add your own security protocols, or modify the authorization steps to match your specific project architecture.
