Web Security for Developers

The web is a great software delivery platform, making your software available to users around the world with zero installation and easily deployed updates. Unfortunately, it also exposes you to an army of adversaries - some human, some bot - who have darker goals: to cause loss to your data or reputation, subvert your resources for their own gain or attack your user base.

This course helps you to develop a security-oriented mindset. It explores the way the web works, so you have a way to understand how various vulnerabilities arise. Then, with those foundations laid, it covers a range of common and less common vulnerabilities, how an attack based on them would be constructed, and how you can recognize and defend against them.

Target audience

This course is aimed at web developers.


You should have basic web development experience.
