Securing a REST API with OAuth 2.0
In this course, you'll learn how to secure a Spring Boot REST API with Spring Security and OAuth 2.0. From leveraging Spring Security defaults, JWT-based authentication and authorization, to secure integrations, you'll learn the best practices for securing your APIs, and implement these best practices in our hands-on labs.
What you'll learn
From security-first defaults to unlimited customization, Spring Security is the most powerful package for securing your Spring Boot API with OAuth 2.0. But how do you actually use Spring Security, and how do you know when not to configure anything at all and just let Spring Security do it for you?
In this course you'll learn:
- The security risks of an unsecured Spring Boot API
- How to leverage Spring Security's default settings
- How to add OAuth 2.0 to your app
- How to work with integrations securely
- And, of course, how to write automated tests for everything!
Before you begin
This course is designed for developers who are new to Spring Security. We recommend having the following knowledge or experience before getting started:
- Module 1: Secure Defaults
- Module 2: Authentication
- Module 3: Authorizaton
- Module 4: Integrations
Learn what you will learn.
Lab: The Unsecured API
Learn how dangerous an unsecured REST API can be for your application.
Learn how simply adding Spring Security to your project puts you on the path to a more secure application.
Lab: Spring Security's Defaults
Secure our application with a couple of lines of configuration.
Get started with Spring Security authentication.
Limits of HTTP Basic
This lesson covers the limits of HTTP Basic authentication, showing why it is not suitable for many production REST APIs.
OAuth 2.0 and JWT
You down with JWT? Yeah, you know me!
Lab: Adding OAuth 2.0 Bearer JWT Authentication
Implement JWTs in our Cash Card application.
Accessing Authentication in Spring MVC
Implement secure and personalized features based on the user's authentication details in your Spring MVC application.
Lab: Accessing Authentication in Spring MVC
Learn the many ways you can access Spring Security authorization information in a Spring Boot app.
The Big Picture
The heart of Spring Security is still beatin': the Spring Security Filter Chain
