Learning Path

Writing Secure Code in Node.js

In this learning path, you will learn how to attack and protect Node.js applications.

What you will learn

Node.js is the most popular server-side asynchronous runtime. Applications built with this technology heavily depend on the NPM ecosystem. Through this learning path, you will learn to attack and protect Node.js applications, covering many different attack types from the perspective of the Node.js side. You will also learn about Node.js-specific attacks such as prototype pollution and their real impact on your applications.
