Implementing security features in a Spring Boot application can be achieved using Spring Security. Configure authentication, authorization, and role-based access control. Utilize annotations like @Secured or @PreAuthorize for method-level security. Extend WebSecurityConfigurerAdapter to customize security settings. Encrypt passwords securely using bcrypt or PBKDF2.
Implement custom security filters for additional checks. Enable HTTPS for secure communication. Integrate with external providers like LDAP or OAuth for centralized authentication. Secure Actuator endpoints for managing sensitive information. These measures ensure robust protection against unauthorized access and maintain the integrity of Spring Boot applications.
