Phase 16 · Security Across the Stack
TopicsXSS & CSRF Protection
Part of the Full Stack Developer Roadmap.
Summary
Preventing malicious scripts from executing in your frontend (XSS) and preventing forged requests using a logged-in user's session (CSRF) — defenses needed on both sides of the stack.
How to Learn This

- 2Implement CSRF protection if you're using cookie-based sessions.
- 3Sanitize any user-generated content that gets rendered as HTML anywhere in your app.
