This chapter explains how to secure your Spring Boot backend. Securing your backend is a crucial part of code development. Securing your backend is essential to protect sensitive data, comply with regulations and prevent unauthorized access. The backend often handles user authentication and authorization process. Securing these aspects properly ensures that only authorized users can access the application and perform specific actions. We will use the database application that we created in the previous chapter as a starting point.In this chapter, we will cover the following topics:
- Understanding Spring Security
- Securing your backend with a JSON Web Token (JWT)
