Spring Boot Application Security Fundamentals

Building functional applications is only half the battle; ensuring they are secure against modern threats is critical for any developer. This text-based course guides you through the essentials of securing Java web applications. You will transition from writing unsecured APIs to designing robust, protected systems. What you'll learn: 1. Understand core security concepts, including authentication vs. authorization and common web vulnerabilities. 2. Configure Spring Security using the modern lambda DSL style for clean, readable security configurations. 3. Implement robust user management with secure password hashing using BCrypt. 4. Protect routes and API endpoints using role-based and permission-based access control. 5. Apply method-level security to secure your business logic directly within your services. 6. Integrate OAuth2 and OpenID Connect for secure third-party login flows. 7. Secure stateless REST APIs using JSON Web Tokens. The course starts with essential security terminology and foundational concepts before moving into practical configuration. You will read through step-by-step explanations, review secure code snippets, and learn how to apply these security patterns to real-world scenarios. This course is designed for Java developers who are new to application security and want a solid foundation in Spring Boot security practices. No prior security experience is required, though basic familiarity with Spring Boot is helpful. Start reading today to build secure, production-ready Java applications with confidence.
