The goal of this course is to review common web security vulnerabilities and exploits, as well as their corresponding defenses. There is an inherent tension between "web as simple document reader" and "web as application environment", and as the functionality of the web ecosystem increases, so do the vulnerabilities.
General concepts that students will learn: principles of web security, attacks and countermeasures, the browser security model, web app vulnerabilities, injection, denial-of-service, TLS attacks, privacy, fingerprinting, same-origin policy, cross site scripting, authentication, JavaScript security, emerging threats, defense-in-depth, techniques for writing secure code, web archiving, rehosting.
Specific technologies that students will learn: Git/GitHub, DOM/Javascript, CLI, Node.js, Twitter, Youtube.
This course is based on CS 253 Web Security, Stanford, Fall 2019. Special thanks to Feross Aboukhadijeh for generously sharing his course materials (although any errors are mine).
