Defensive Web Fundamentals

Defensive Web Fundamentals introduces the core ideas behind how the web works and why web systems are such common security targets. You probably use websites every day, but using them doesn't mean you understand what's happening between the browser, the server, the application, and the data behind the page. This course builds that understanding specifically for defensive work.
