Nodejs development: How To Secure the Application

Node.js is a cross-platform, open-source back-end JavaScript runtime environment that uses the V8 engine to execute JavaScript code outside of a web browser. NodeJS is a very secure platform, but in the current era, you need to take more care when the app’s security is considered. You can also hire Nodejs Development Services to develop a secure app.

NodeJS is a popular web app development framework trusted by many big brands like Netflix, LinkedIn, PayPal, etc.

In the current era, online threats and vulnerabilities have increased a lot. Thus, it is necessary to take extra care of the app’s security.

An app has a lot of data, and it contains a lot of customers’ sensitive data, which you need to protect. It is the responsibility of the brand to protect the customers’ data and assure them of security.

In this post, we will give you tips to secure your application.

8 Tips to secure your application 

  • Regulate HTTP headers 

You must use secure headers to combat cross-site scripting (XSS) and various other types of malware attacks that can attack your NodeJS application. You may construct your node JS security lesson using modules like the helmet, which is readily adjustable. 

  • Linter security

By using Linting, you can eliminate the potentially dangerous patterns in your code. In addition, you can use various plugins to catch threats and vulnerabilities while coding the NodeJS application. The security of your Nodejs Development is critical, and you can use various security plugins to secure your app.

  • Implement strong authentication

If you have a weak or broken authentication, it can be a threat to your company. Many developers think just having an authentication is enough, but it is not; you require strong authentication for your app and not just a simple authentication. If you want to use native Node.js authentication, keep a few things in mind. Use Bcrypt or Scrypt instead of Node.js’ built-in crypto library for constructing passwords. You must limit the number of failed login attempts; don’t allow any user to log in after some attempts. You can tell them that their login credentials are incorrect, and they can now try after some time. Also, it would be best if you implemented 2FA authentication to enhance your app security. 

  • Logging and monitoring

Your goal must be to secure your app or system from the beginning, then only you will achieve a secure app. For this purpose, you need logging & monitoring. Logging and monitoring will help you know if anything is wrong with the application. With just logging, you may not get enough information, and thus you can need to use monitoring as well. 

  • Run vulnerability scanning

NodeJS has many different modules and libraries, and it is very common for you to use a lot of them in your projects. But this can create a security issue for you, and to solve this problem, you must run automated vulnerability scanning. It will help you to find vulnerabilities. You can also make use of the npm audit for the basic check. It would be good if you use regular test exercises as it will help to improve the logging and monitoring policies. It will also help your team establish response and recovery plans in case of any security breach. 

  • Enforce access control on every request

Broken access can give freedom to the online attackers to gain access to the app. And broken access results due to insufficient functional testing by application developers. One method to avoid this vulnerability is manually testing application modules requiring user permissions. In addition, access control rules and middlewares are best implemented on the server-side since this prevents the potential of cookies or JWT (JSON Web Token) authorization tokens influencing access rights on the client side.

  • Run Node.JS as a non-root user

A user process has the least access to the system’s data and resources. An attacker with root access, on the other hand, can gain full control of the local system and divert traffic to other servers. 

  • Limit the payload size

Your Node.JS application may receive a large number of requests, and due to this, you may face difficulty in processing other important tasks. And also, due to a large number of requests, your app performance may get affected; it may also expose your app to DOS attacks. A single thread for large claims executes a larger body payload. Because of the larger payload size, attackers can represent a hazard even if they do not make several requests. You may use express body-parser to limit the size of the body by only accepting short payloads.

Conclusion

In conclusion, we would say that NodeJS is a popular and secure framework for developing apps, and many big brands also trust it. But seeing the rise of online attacks and data breaches, security has become a major concern for every brand. Thus, it has become essential to make your application fully secure. The tips that we have mentioned in this post can help you make your NodeJS application fully safe & secure.
