Secure Your Spring Applications with Spring Security 6 and JWT
Spring Security is the standard security framework for Java applications built on Spring Boot — handling authentication, authorization, OAuth2, and token management in production systems worldwide. This track covers Spring Security 6, the major release that replaced WebSecurityConfigurerAdapter with a cleaner component-based model, alongside JSON Web Tokens as the stateless authentication mechanism that most REST APIs rely on today. Twelve focused courses take you from initial project setup through production hardening.
What You Will Learn
You will configure Spring Security 6 from scratch, implement custom authentication providers and password encoding, and define fine-grained authorization rules. The track covers OAuth2 and OpenID Connect — both as a client and as a resource server — so you understand the full token flow. On the JWT side you will learn how tokens are structured, signed, and validated, then wire them directly into the Spring Security filter chain. Later courses address advanced token management, multi-factor authentication, rate limiting, and performance considerations for high-traffic deployments.
The Learning Path
Twelve courses span A2 to C1. The opening course, Spring Security 6 Fundamentals & Setup, establishes the project structure and core concepts at A2. The B1 block covers Custom Authentication & Password Encoding, Authorization & Web Security Configuration, and an OAuth2 & OpenID Connect Introduction. B2 courses move into JWT Fundamentals, Integrating JWT with Spring Security, and both OAuth2 client and resource server configuration. The four C1 courses — Advanced JWT Management & Security, Advanced Token Security & Performance, Multi-Factor Authentication & Rate Limiting, and Production Security & Deployment Best Practices — close the track at professional depth.
How It Works
Each course is split into short, hands-on lessons you complete in the built-in code editor with real-time feedback. An AI tutor is available whenever you get stuck, explaining why a filter chain is misconfigured or why a JWT signature fails — without just handing you the answer.
