Microservices are no longer a novelty. We’re seeing large-scale microservices deployments with thousands of services. But whether we have one or two services or thousands, security is a top priority. This part of the book takes you through the fundamentals in securing microservices.
Chapter 1 teaches you why securing microservices is challenging, and takes you through the key principles in securing a microservices deployment.
Chapter 2 teaches you how to build your first microservice in Spring Boot and secure it with OAuth 2.0. You will also learn how to set up an OAuth 2.0 token issuer.
When you’re finished with these two chapters, you’ll have the right mindset to take on the challenges of securing microservices. After getting your feet wet in this part of the book, you’ll be ready to build more complex security patterns (which we teach you in the rest of the book) on top of your first microservice.
