This course is your guide for securing Node.js applications. You'll start by properly sanitizing user input and output, and then move on to some fundamental protocols, such as HTTPS and SHA. Passwords and encryption will be discussed next. More specifically, you will learn about different hashing algorithms and protecting your application from brute force attacks.

Following that, you'll explore concepts like authentication, access control, and obfuscation. You will also learn about XSS, CSRF, and other popular hacks near the end of the course.

By the end of this course, you will know how to secure a Node.js application, an in-demand skill to put on your resume!

A Guide to Securing Node.js Applications

# What is typecasting?
One additional step, for security and data integrity, is to typecast known formats. Since JavaScript is dynamically typed, a value can be any type. By typecasting the value, you can verify that the data matches are what you expect. Recall the [previous](https://www.educative.io/courses/securing-nodejs-apps/how-to-guard-against-sql-injection) MySQL example. If the ID came from a variable, it would make sense to typecast it, only if you know it should always be an integer, like this:
