In this chapter, we covered the basics of security requirements while we are building an application with a Microservices-based design. We started with a JWT-based security implementation, and then discussed JSR 375 (the Java Security API). Following that, we talked about Spring Security and its implementation with respect to Spring-Boot-based Microservices. Finally, we discussed the usage of HTTPS when communicating over the internet.

In the next chapter, we will focus on monitoring Microservices-based applications.
