Chapter 5 of Learning #SpringBoot almost done!
This Thursday I’ll be submitting the first draft for Chapter 5 – Securing Your App with Spring Boot inside Learning Spring Boot. If you have no experience with Spring Security, then I hope you’ll enjoy this chapter. Security by itself is a complex topic. There is no single thing that instantly makes your entire application secure from everything.
Spring Security is a powerful application level security tool. You get very detailed control and can customize to your heart’s content. But as is often the case, people want to use some basic settings that enact a common security model: authentication and authorization.
When you add Spring Security to a Spring Boot project, things get automatically locked down. This is handy for demos, but this chapter will show you can then go in and configure things more to your liking. My plan is to walk through in-memory based options (good for testing and getting started) as well as a configuring a couple different databases that are commonly used. With that sort of introduction to Spring Boot + Spring Security, it becomes much easier to read the online reference docs if you want to cut over to an LDAP-based user data store.
As I said earlier, security doesn’t start and end at the application level. I want this chapter to be comprehensive in the sense that security doesn’t end at the application level. Spring Boot does a fantastic job of inverting the concept of a container by having the app bring along embedded Tomcat to run itself. In this chapter, we’ll see how to configure Spring Boot’s embedded Tomcat servlet container use SSL, strengthening the end-to-end security of your app.
