Node.JS Security Best Practices to Follow

NodeJS Security Best Practices

For building backend APIs and web applications, NodeJS has proven to be one of the best frameworks for runtime JavaScript code bases. Since it is asynchronous, developers have the leverage to develop innovative software solutions with nonblocking events running on a single thread.

Although NodeJS comes with an array of advanced features, there is always a question of security and privacy when considering applications interacting directly with the users. Several cyber crimes and hacking cases have been reported in the last couple of years. In addition, with the increasing pace of digitalization, online safety has become a major concern for many businesses and organizations.

Therefore, if you hire remote NodeJS developers, you should ensure they know the top security practices for making the applications more secure and safer. This article will walk you through the major ways you can implement security in the note application.

Validate SQL Injection Query

In most NodeJS applications, the user sends a request as a database query from the front end to the back end DB. Usually, no validation is used to verify if the query sent to the database from the front end has any malicious content or not. 

A hacker can easily manipulate the data in a query and send a command that can wipe out the entire database or clone the tables to get free access to all data. 

The best way to prevent such kind of SQL injection query is to validate the user input from the front end. Several types of databases exist where built-in validation is already present to ensure hackers cannot get entry to the server and the on-site database through injection queries.

Prevents XSS Attacks

In a cross-site scripting attack, hackers use JavaScript code to gain access to the main code base of the application and the database. When the person includes the JavaScript code inside a database query, it is executed without restriction. 

As a result, unintentional functions are performed on the application that might cause it to shut down completely or allow the hacker to have unhindered access to store user data and sensitive information.

Like SQL injection, the cross-site scripting attack can be prevented by implementing front-end query validation. You should not allow the use of any random database for NodeJS applications as it won’t be able to verify the input and block it if any JavaScript code is presently encoded within the query.

Implementation of a Strong Authentication Layer

Suppose the NodeJS application collects user-sensitive data and stores it in an on-site or cloud server. In that case, it is crucial to ensure you hire NodeJS developers who understand encryption and authentication. 

There are several ways of securing an application through multiple layers of authentication. Usually, applications have a simple login or sign-up portal with a user ID and password. These details are easy to hack and therefore don’t provide the ultimate security.

You can implement authentication processes like Okta or auth indicated to ensure the application is fully secured. This will generate a push notification on the mobile either as a confirmation message or a one-time password. 

Either way, only the user can access the application because, without the password or the confirmation, the application won’t allow any other person access.

Practical Error Handling Logic

Sometimes, errors are encountered when a code is executed, or an API is run. When you check the log from the back end, you get the full stack dress of the defect, comprising the packages, path, process services, line numbers, functions, and so on where the error has occurred. These information pieces are necessary for a developer to take the debug and check the root cause.

However, it is not of any use to a user. Therefore, when you apply logic in the code for error handling, ensure the error message is abstracted, and only a certain portion is shown to the users. 

Similarly, ensure you wrap all the routes to prevent the application from crashing if it encounters any error from the front-end requests. As a result, hackers won’t be able to send any request that can cause your application to shut down completely.

Schedule Automatic Scanning For Vulnerabilities

The NodeJS platform comes with hundreds of built-in libraries and code snippets. You include them in your code base to reduce effort and time because you don’t have to write everything from scratch. 

However, there is one problem in terms of security. As the library packages and functions were coded by someone else, you don’t have the guarantee that they are completely secured and won’t open a back door for the hackers.

This is why scheduling automatic scans for code vulnerabilities is crucial when dealing with NodeJS applications. The testing will provide a detailed insight into the app’s health, letting you know if there is any vulnerability in the code which can allow easy access to the hackers. 

In addition, you won’t have to wait for a data breach to understand whether any back door is open in the encryption layers or not.

Implement The Use of Security Linters

Security linters are almost like error catchers you can implement during code development. For example, when you write a syntax wrong, the NodeJS framework instantly notifies you about the error. This way, you don’t have to wait for the compilation to happen to identify where the error is and understand the root cause.

Similarly, instead of waiting for the scheduled automatic vulnerability scan to run, you can take the security to the next level by implementing linters. These filters notify you about any erroneous or unsafe code used during the development. As a result, you can easily remove or modify that block to make the statements safer and less vulnerable to attacks.

Make the Configuration Files Transparent

When you hire remote NodeJS developers, you should ensure they have complete knowledge about configuration files and their safety. These files have details about how you configured the application, the orchestrated workflow, integration details, environment data, source code, and so on. 

In most cases, developers used to store the configuration files in unsecured repositories. As a result, hackers could easily access these files and know everything about the back end of your application.

Therefore, you should not hide any secrets in the configuration files. Instead, you can implement the concepts of continuous integration and continuous deployment to ensure the coded secrets stored in the config files are integrated properly and deployed regularly.

Orchestrate Production Security For a Node Application

Last but not least, you have to implement appropriate security measures for production. Once the node application is developed, you must release the code to merge with the production environment. Since it interacts with the users upfront, you should put multiple validation layers so that no front-end query or request can trigger any unwanted JavaScript code or database query.

Also, every developer must close all possible backdoors and prevent data leakage. There is nothing like a 100% secure application, but you can achieve 99% security by implementing some of these techniques in the production environment of the node application.

How can to secure Node.js applications against common vulnerabilities

Now let’s understand how you can secure your Node.js application against common vulnerabilities. By following these best practices, you can protect your application and user data from potential threats.

  1. Keep Dependencies Up-to-Date

One of the primary sources of vulnerabilities in Node.js applications is outdated dependencies. Regularly update your project’s dependencies, as developers often release patches and updates to fix security issues. Utilize tools like npm audit to check for known vulnerabilities in your project’s dependencies and address them promptly.

  1. Implement Input Validation

Inadequate input validation is a leading cause of security vulnerabilities. Ensure that your application thoroughly validates and sanitizes all user inputs. Use libraries like express-validator to simplify the input validation process and prevent common attack vectors like SQL injection and cross-site scripting (XSS).

  1. Avoid Callback Hell with Promises or Async/Await

Callback hell, also known as the “pyramid of doom,” can make your code harder to read and maintain. Using Promises or async/await makes your code more manageable and can help prevent race conditions and callback-related vulnerabilities.

  1. Set Secure HTTP Headers

HTTP headers play a crucial role in web security. Configure your Node.js application to set secure HTTP headers, such as Content Security Policy (CSP), X-Content-Type-Options, and X-Frame-Options. These headers can help prevent cross-site scripting attacks and other common web vulnerabilities.

  1. Use Authentication and Authorization

Implement strong authentication and authorization mechanisms to control access to your application’s resources. Popular libraries like Passport.js can simplify the authentication process, while access control lists (ACLs) and role-based access control (RBAC) can help manage authorization.

  1. Protect Against Cross-Site Request Forgery (CSRF)

To prevent CSRF attacks, use tokens in your forms and APIs. Libraries like csurf can automatically generate and verify these tokens. Additionally, always require the SameSite attribute on cookies to prevent cross-origin requests from potentially compromising your application.

  1. Employ Secure Authentication Methods

Avoid storing passwords in plain text or using weak encryption. Instead, use strong, industry-standard hashing algorithms like bcrypt to securely store user passwords. Implement multi-factor authentication (MFA) for an extra layer of security.

  1. Logging and Monitoring

Implement comprehensive logging and monitoring for your application. Monitoring tools like New Relic, Sentry, or custom solutions can help you detect and respond to unusual activity or potential security breaches promptly.

  1. Regular Security Audits and Penetration Testing

Periodically conduct security audits and penetration testing to identify and address vulnerabilities in your Node.js application. Hiring a professional penetration testing team can help you discover hidden weaknesses.

  1. Secure APIs

If your Node.js application serves as an API server, ensure it follows RESTful API security best practices. Implement OAuth 2.0 for user authentication and authorization to protect your APIs from unauthorized access.

  1. Deploy a Web Application Firewall (WAF)

Consider deploying a web application firewall (WAF) to provide an additional layer of security. A WAF can filter and block malicious traffic before it reaches your application, offering protection against common attacks such as SQL injection and cross-site scripting.

How to Secure RESTful APIs in Node.js

They enable seamless communication between client-side and server-side applications, making them a fundamental component of the Internet. However, this increased reliance on RESTful APIs also means that securing them is of paramount importance. In this blog post, we will explore various strategies and best practices for securing your RESTful APIs in a Node.js environment.

1. Use HTTPS (SSL/TLS): Secure Sockets Layer (SSL) or Transport Layer Security (TLS) is the first and most fundamental step in securing your RESTful APIs. By encrypting data in transit, you protect it from eavesdropping and tampering. Node.js offers excellent support for HTTPS, and services like Let’s Encrypt make it easier than ever to obtain and manage SSL certificates.

To set up HTTPS in Node.js, you can use the built-in ‘https’ module. Here’s a simplified example:

setup HTML in node js

2. Implement Authentication:

a. Token-Based Authentication: Token-based authentication, such as JSON Web Tokens (JWT), is a popular choice for RESTful APIs. In this method, clients receive a token upon successful login, which they include in their requests. The server validates this token for each request.

Here’s an example of using JWT with Node.js and the ‘jsonwebtoken’ package:

using JWT with Node

b. OAuth2: OAuth2 is an industry-standard protocol for authorization. It enables third-party applications to access your RESTful APIs on behalf of the user. Implementing OAuth2 in Node.js can be done using packages like ‘passport’ and ‘oauth2orize’.

3. Rate Limiting: To prevent abuse or DDoS attacks on your RESTful APIs, you should implement rate limiting. With rate limiting, you can restrict the number of requests an IP address or user can make within a given timeframe. The ‘express-rate-limit’ package can help you achieve this.

4. Input Validation and Sanitization: Always validate and sanitize user input to protect your RESTful APIs from SQL injection, cross-site scripting (XSS), and other attacks. Using libraries like ‘express-validator’ can simplify this process.

5. Error Handling: Handle errors gracefully and avoid exposing sensitive information. Use custom error messages instead of revealing internal details about your application. You can create a centralized error handler middleware in your Node.js application to achieve this.

6. Cross-Origin Resource Sharing (CORS): Implement CORS to control which domains can access your API. This prevents unauthorized websites from making requests to your API and helps protect against cross-site request forgery (CSRF) attacks.

Here’s an example of enabling CORS with the ‘cors’ package:

enabling CORS

7. API Versioning: Always version your APIs to maintain backward compatibility. This ensures that changes to your API won’t break existing clients and allows them to migrate at their own pace. You can implement API versioning in your routes and controllers.

8. Logging and Monitoring: Implement comprehensive logging and monitoring to keep track of any unusual activities or security breaches. Tools like ‘Winston’ and services like ‘Sentry’ can help with this.

9. Regular Security Audits: Conduct security audits and penetration testing of your RESTful APIs periodically to identify and fix vulnerabilities before they can be exploited by attackers.

10. Keep Dependencies Updated: Regularly update your Node.js and package dependencies to ensure that you are protected against known security vulnerabilities.

In conclusion, securing RESTful APIs in Node.js is a multi-faceted task that involves encryption, authentication, rate limiting, input validation, error handling, and many other considerations. By following these best practices and staying up-to-date with the latest security trends, you can build robust and secure RESTful APIs to protect your data and users. Remember that security is an ongoing process, and vigilance is key to maintaining a strong defense against evolving threats in the digital landscape.
