Foundations of Spring Security for Spring Boot Applications

Securing web applications is a critical requirement for any modern developer, yet implementing robust security can feel overwhelming. This text-based course demystifies access control, helping you confidently protect your Java applications from unauthorized access. You will transition from relying on default, auto-generated settings to writing clean, customized security configurations. By reading through clear explanations and analyzing practical code snippets, you will learn how to handle user credentials, manage roles, and implement modern security practices. What you'll learn: Understand core security concepts like authentication, authorization, and servlet filters; Configure custom user details services and secure password storage using modern hashing algorithms; Implement role-based and authority-based access control to restrict specific application endpoints; Apply modern configuration patterns using the latest non-deprecated Spring Security DSLs; Explore the fundamentals of stateless token-based authentication and basic OAuth2 concepts; Practice securing REST APIs against common web vulnerabilities like CSRF and CORS misconfigurations. The course starts with essential security definitions and architectural concepts before guiding you through step-by-step configuration scenarios. You will progress from basic in-memory setups to database-backed authentication and modern stateless security patterns. This course is designed for beginner Java and Spring Boot developers who want to learn application security from scratch. No prior security experience is required.
