How to Secure APIs and Services Using OpenID Connect

Kong, a modern API gateway, offers a more efficient approach to API management compared to traditional gateways by integrating seamlessly with other platforms through its pluggable architecture. Unlike older solutions that attempt to bundle numerous features into a monolithic structure, leading to inefficiencies, Kong leverages a best-in-breed approach that allows it to be fast, scalable, and user-friendly. This blog post highlights how Kong can integrate with identity providers (IdPs) like KeyCloak to manage authentication and authorization without the need to maintain separate user and group management systems within the gateway itself. By utilizing OpenID Connect and JWT tokens, Kong enables the central IdP to handle user identity and entitlements, streamlining API security and reducing operational overhead. Through a practical example with KeyCloak, the post demonstrates how to configure Kong to secure APIs and services, allowing access based on defined scopes within JWT tokens, thus ensuring efficient identity management and access control.
