Implementing Zero Trust Architecture with OAuth 2.1 and OpenID Connect 1.1: A Practical Guide

Opening Hook

You've just deployed your application, and you're concerned about securing your API gateways. As a developer, you know that security is a top priority, but you're not sure where to start. In this article, we'll explore how to implement Zero Trust Architecture using OAuth 2.1 and OpenID Connect 1.1.

Why This Matters

The current state of API security is a major concern in the industry. With the rise of microservices and cloud-native applications, the attack surface has increased significantly. OAuth 2.1 and OpenID Connect 1.1 are the latest standards for securing APIs, and understanding how to implement them is crucial for any developer.

Background/Context

OAuth 2.1 and OpenID Connect 1.1 are built on top of the OAuth 2.0 and OpenID Connect 1.0 standards. The new versions provide improved security features, such as proof-of-possession tokens and better support for native applications. The current ecosystem includes a wide range of libraries and frameworks that support these standards, making it easier to implement them in your application.

Core Concepts

The core concept of Zero Trust Architecture is to verify the identity of every request, regardless of whether it's coming from inside or outside the network. OAuth 2.1 and OpenID Connect 1.1 provide the necessary tools to implement this architecture.
