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!

You need to ensure that a user is who they say they are.

We need to decide whether a user has access to the page/section/feature they are requesting. We can *control* their *access* based on their user type, e.g., admin or muggle.

Someone can bypass your expected flow by simply sending a request straight to this final page. This can allow them to skip your validation step.

Why do we need to validate redirects?

At times, we do not want to expose the user to the data that we are using in our application. This data can be things like user IDs or table headers.
