Spring Security 6 Full Course | Crack Interviews in One Shot

🔐 Complete Spring Security 6 Tutorial Welcome to the Ultimate Spring Security 6 Full Course. In this complete tutorial, we go step by step — from understanding how Spring Security works internally to implementing modern authentication and authorization mechanisms used in real-world applications. This is not just configuration — we focus on architecture, filter chain flow, authentication processing, and production-ready security design. 1️⃣ Form-Based Authentication (Session Authentication) We begin with default form login and session-based authentication. You’ll understand how Spring Security automatically secures your app, how JSESSIONID works, how sessions are created, and how authentication is maintained using cookies. We also deep dive into: SecurityFilterChain UsernamePasswordAuthenticationFilter AuthenticationManager & AuthenticationProvider DaoAuthenticationProvider This builds your core foundation of how authentication works internally. 2️⃣ CSRF (Cross-Site Request Forgery) Next, we understand how CSRF attacks happen in real browser scenarios and why session-based applications are vulnerable. You’ll learn: How CSRF exploits cookies Why it affects POST/PUT/DELETE requests How Spring Security generates and validates CSRF tokens How CSRF protection works behind the scenes This section helps you think like a security engineer. 3️⃣ Basic Authentication (Stateless Authentication) We then move to Basic Authentication and understand stateless security. You’ll learn: How Base64 credentials are sent in headers Basic vs Session authentication Custom SecurityFilterChain configuration Database integration with UserDetailsService PasswordEncoder & BCrypt Secure password storage Custom login & UserDetails implementation This clarifies authentication strategies for REST APIs. 4️⃣ JWT Authentication (Token-Based Security) Now we implement production-ready JWT authentication. You’ll understand: JWT structure (Header, Payload, Signature) Claims, expiration & signature verification JWT vs Session vs Basic Creating token generation APIs Implementing a custom JWT filter Setting authentication in SecurityContext End-to-end stateless authentication flow This section prepares you for real-world API security. 5️⃣ Authorization (Roles & Permissions) Authentication verifies identity. Authorization controls access. Using a Hotel Management example, we implement: Role-Based Access Control Permission-Based Authorization hasRole vs hasAuthority GrantedAuthority @PreAuthorize & @PostAuthorize AuthorizationManager internals Storing roles inside JWT You’ll learn how to design scalable authorization systems. 6️⃣ OAuth 2.0 (Google Login Implementation) Finally, we deeply understand OAuth 2.0 using a real-world Google login example. You’ll learn: OAuth 2.0 architecture (Client, Authorization Server, Resource Server) Authorization Code flow Scope, state parameter, redirect URI Access token generation Implementing OAuth2 login in Spring Boot Integrating Spring Security 6 with Google This gives you both conceptual clarity and hands-on implementation. By the end of this course, you’ll have a strong foundation in Spring Security 6 — from session-based authentication to JWT and OAuth2 — with a clear understanding of how everything works internally. If you're serious about mastering Spring Security, this complete tutorial will give you the clarity and confidence you need. 🔐 00:00:00 : Introduction 00:01:12 : Form and Session Based Authentication 00:26:24 : CSRF Attack & CSRF Token 00:45:24 : Basic Auhentication 01:26:29 : JWT (JSON Web Token) 02:13:12 : Authorization (Roles & Permissions) 03:04:23 : OAuth 2.0 Instagram :   / the.curious_coder   #interview #springboot #java #springsecurity
