Deep Dive Spring Security

This course offers a comprehensive, hands-on guide to Java Spring Security, designed to help developers build secure, real-world Spring Boot applications with confidence. Security is no longer optional in modern software development, and Spring Security is the industry-standard framework used to handle authentication, authorization, and protection against common security vulnerabilities.

You will begin by learning the core concepts of Spring Security, including how the security filter chain works, how requests are intercepted, and how authentication and authorization are applied behind the scenes. The course then walks you through setting up Spring Security in a Spring Boot project, configuring form-based login, logout, and securing URLs using roles and authorities.

As you progress, you will work with user authentication using multiple approaches, including in-memory users, database-backed authentication with JPA, password encoding using BCrypt, and custom UserDetailsService implementations. You will also learn how to restrict access to endpoints using annotations and method-level security.

The course covers important real-world security topics such as session management, protection. You will also secure REST APIs.

By the end of this course, you will have a solid understanding of how Spring Security works internally and how to apply best practices to secure enterprise-grade applications. This course is ideal for Java and Spring Boot developers who want to advance their backend skills and build production-ready, secure applications using Spring Security.
