Before I discuss with you how to secure Node.js Application, first let’s have an overview of Node.js and what is all about.

Node.js is an open source, cross-platform runtime environment for developing server-side and networking applications. Node.js applications are written in JavaScript, and can be run within the Node.js runtime on OS X, Microsoft Windows, and Linux.Node.js also provides a rich library of various JavaScript modules which simplifies the development of web applications using Node.js to a great extent (TutorialPoints, 2020).

Now that we know what is Node.js, we will discuss how to keep your application secure from malicious dependencies.

There are some preventive action you can take to avoid your application being 

– Lock your dependencies. Use package-lock.json or yarn.lock to prevent getting automatic updates when deploying (when doing npm/yarn install in your server). At least this way you will get fewer chances of getting a malicious update that the npm team hasn’t cleaned up yet.

However, this wouldn’t have prevented the event-stream from affecting you since the malicious code was available in the npm registry for weeks.

-Use npm audit, Snyk and/or GitHub security alerts to be notified when any of your dependencies could contain security vulnerabilities.

When perform all these action in order to secure your application not only is a important step to prevent attack but it also very important to know most type of attack to better secure your application.

RESPONSE 2:

The Node.js application at its core is Java Script just like the client side. The core of Node.js makes it a target for the same attacks as Java Script. The application itself is vulnerable to SQL injections, Cross-Site Scripting, and Cross-Site Forgery Requests like the client side. Securing Node.js from the server side is the same as client for these attack vectors.

Cross-Site attacks can be defended against by using input validation. Input validation or properly encoded is a basic form for Node.js. The purpose of input validation is for the system to validate to input forms and ensure they are coming from the correct person or system (Sulemani, 2020).

SQL injections are used to find or retrieve information from the server by injecting a SQL statement instead of the field’s normal content (Sulemani, 2020). The use of parameterized statements in the application ensures the inputs are distinguished between data and code (Sulemani, 2020).

The basic security principles also work when securing Node.js applications. Ensuring the account used on the Node.js account is one with the minimal amount of privileges to do the required task (Sulemani, 2020). Hashing and adding salts to passwords inside the Node.js application is a basic security technique to guard the Node.js application. Salts are added to the password before it is hashed to make the Hash longer than it truly is. This technique protects the passwords from dictionary attacks that uses hashes of different words to crack passwords (Sulemani, 2020).

Adding or Removing HTTP headers in Node.js is another method to secure the application. HTTP headers can leak sensitive information about the application if they are not removed or secured properly. The Helemet.js module for Node.js is a security module for HTTP headers that protects against leaks (Sulemani, 2020).
