JavaScript Security: Best Practices from Pluralsight

Learn how to write more secure JavaScript code. This course will teach you how to find, fix, and prevent vulnerabilities caused by unique JavaScript issues such as prototype pollution, dynamic typing bugs, and code injection attacks.

Complex Web applications contain a lot of JavaScript code. Security of those applications depends on how robust this code is. In this course, JavaScript Security: Best Practices, you’ll learn how to improve the security of your JavaScript code. First, you’ll explore how exploiting the dynamic type system may lead to information disclosure vulnerabilities. Next, you’ll discover how JavaScript dynamic code execution functions can allow attackers to run arbitrary code within your application. Finally, you’ll learn how abusing prototypal inheritance may change the behavior of your application in unexpected ways. When you’re finished with this course, you’ll have the skills and knowledge of JavaScript security best practices needed to protect your web applications against attackers.
