Security Concepts

A one-page guide to web security basics, from XSS and CSRF to JWT, CORS and security headers, with live demos.

Fundamental Security Concepts: a list of topics from XSS to CORS, and an interactive XSS demo comparing unsafe and sanitised rendering of a payload.

The concepts every web developer should know, each with a short explanation and, where it helps, a demo to try: type a payload and watch the unsafe render run it while the sanitised one doesn’t.
