CSRF Attack Quiz: Test Your Web Security Knowledge

📚 Quick Study Guide

🔍 CSRF (Cross-Site Request Forgery) attacks exploit the trust a website has in a user's browser. 🛡️ The attacker tricks the user into performing actions they didn't intend to on a trusted site. 🔑 Prevention methods include: 🔐 Synchronizer Token Pattern: Using a unique, unpredictable token in each request. 🍪 Double Submit Cookie: Setting a cookie and including its value in a form field. 🌐 SameSite Cookie Attribute: Restricting cookie usage to the same site. 🛂 Checking the Origin header: Validating that the request originated from the expected domain. 🚫 CSRF attacks target state-changing requests (e.g., transferring funds, changing email addresses).
