About This Course

Web security is no longer optional — it is the foundation every developer must build on. Modern Web Security Fundamentals takes you from zero to confident defender in just five days. You will walk through each of the OWASP Top 10 risks with practical, code-level demonstrations so you understand not only what can go wrong, but why it happens and how to fix it. By the end of this course you will be able to audit a web application for cross-site scripting, injection flaws, and broken authentication. You will know how to set the right HTTP security headers, implement CSRF tokens, and design login flows that resist brute-force and credential-stuffing attacks. Every lesson includes a mini-lab you can run locally so the knowledge sticks.
