Spring Security and JWT: Modern Web Authentication in Java

Securing web applications is a fundamental requirement for modern backend development. This text-based course guides you through the core concepts of web security using Spring Security, the industry-standard framework for Java applications.\n\nYou will transition from understanding basic security principles to configuring robust, production-ready authentication and authorization mechanisms. You will learn how to protect REST APIs, manage user roles, and implement modern stateless authentication using JSON Web Tokens (JWT).\n\nWhat you'll learn:\n- Understand foundational security concepts, including authentication, authorization, and common web vulnerabilities.\n- Configure Spring Security using the modern lambda-based DSL configuration style.\n- Implement stateless session management and secure REST endpoints using JSON Web Tokens (JWT).\n- Apply role-based and authority-based access control to restrict user actions.\n- Build custom security filters to intercept and validate incoming web requests.\n- Practice user auditing and secure password hashing techniques.\n\nThe course starts with essential security terminology and architecture before moving step-by-step through configuration, custom filters, and JWT integration. You will read clear explanations and study structured code snippets designed to build your practical security skills.\n\nThis course is designed for Java developers who are new to Spring Security. No prior security experience is required, though a basic understanding of Spring Boot is recommended.\n\nStart writing secure Java applications today and protect your users with confidence.
