Since its creation in 2009, Node.js has seen exponential growth in its community of users and the applications they are building. With the drive towards a connected society, the need for web applications has never been greater. Yet, despite the push to connect the world as we know it, businesses of all sizes fall victim to data breaches everyday. The security risks that a Node.js based web application face are no different than any other web application. This course, Securing Your Node.js Web App, will empower you with both the understanding of various web based security risks and how to apply the proper mitigation in your Node.js web application. First, you'll learn about implementing proper authentication and session management. Next, you'll explore how to protect your MongoDB database from injection attacks and how to handle untrusted data - a key player in many of the risks you'll look at. Finally, you'll wrap up by learning how to control application and user authorization to key access areas and the benefits of serving our application over HTTPS. By the end of this course, you'll be on your way to building a significantly more secure Node.js web application.
