Building Safer JavaScript Applications
Explore JavaScript web application security to mitigate vulnerabilities, handle user input, securely store and transmit data, and understand HTTP and API security. Gain insights for interviews and practice assessments.
JavaScript is one of the most popular and in-demand programming languages today and its usage shows no signs of slowing down. If you use JavaScript for either the backend or frontend, it is crucial to have a firm understanding of web application security in order to keep our users safe.
In this course, you’ll learn how to mitigate the most common JavaScript vulnerabilities and attacks. For example, you will learn why user-provided input should be treated with caution. Then, you’ll see how to safely store sensitive data on the client and the server, and how to securely transmit it across the internet. Finally, after learning about HTTP and API security, you can take an in-depth assessment to test what you've learned.
Questions about web application security often come up in interviews since knowing security principles is a sign of a mature developer. Should input validation happen on the client or the server? Take this course to find out!
