Spring Security 6 | CSRF Attack | CSRF Token
In this video, we deep dive into CSRF (Cross-Site Request Forgery) and understand how a CSRF attack actually takes place in real-world applications, not just theory.
You’ll learn why CSRF is a serious security vulnerability in session-based authentication and how Spring Security prevents CSRF attacks using a CSRF token.
We start by understanding a real browser-based CSRF attack scenario, where a malicious website tricks a logged-in user’s browser into sending authenticated requests without their knowledge. Then, step by step, we break down how Spring Security protects your application by validating CSRF tokens and blocking unauthorized state-changing requests.
This video explains CSRF at both conceptual and implementation levels, making it ideal for Spring Security interviews and real project understanding.
