This course shows you how to build secure Java web apps with Spring Security 6. You learn how the core parts work and how they handle login, roles, and request checks. You also learn how to protect APIs with JWT and OAuth2.

What You Learn

You get clear steps to add security to a Spring app. Each topic includes hands-on work so you can try it on your own.

Spring Security Basics

  • How the Spring Security framework works
  • Main packages, classes, and interfaces
  • How requests move through the security chain

Add Security to a Web App

  • Set up security for a Java web app
  • Use Ant, MVC, and regex matchers to protect URLs
  • Add custom filters when you need extra checks

Password and Data Safety

  • Use PasswordEncoders
  • Know the difference between encoding, hashing, and encryption

Web Protection

  • What CSRF is and how to handle it
  • What CORS is and when it matters

Login and Access

  • What authentication and authorization mean
  • How to use roles and authorities
  • How to add method-level rules

JWT and OAuth2

  • How JWT works in login and access checks
  • OAuth2 grant types and when to use each one
  • OpenID Connect and how it fits with OAuth2

More Features

  • Social login in web apps
  • Set up an authorization server with Keycloak

Who Should Take This

You should know basic Java and Spring. You do not need past security work, but you should want to learn it.
