In this video walk-through, we covered conducting security review for a web application using browser developer tools.

In this room you will learn how to manually review a web application for security issues using only the in-built tools in your browser. More often than not, automated security tools and scripts will miss many potential vulnerabilities and useful information.

Here is a short breakdown of the in-built browser tools you will use throughout this room:

  • View Source – Use your browser to view the human-readable source code of a website.
  • Inspector – Learn how to inspect page elements and make changes to view usually blocked content.
  • Debugger – Inspect and control the flow of a page’s JavaScript
  • Network – See all the network requests a page makes.
