Risks and Solutions for Node.js Applications

Technology brings innovation and creativity increases. Whenever anything becomes popular in terms of technology, slowly it becomes popular with millions of entrepreneurs including attackers, hackers, and security experts. etc. Node.js is secure but when you install it with any third-party package, you need to configure and deploy it to protect web applications.  In this blog, you will learn the different types of Node.js theft and solutions.

Different types of theft of Node.js and solutions

Types of theft

From a security perspective, an attacker can easily modify its prototype and object. Ultimately, it leads to cross-site scripting attacks in the browser then to remote code execution attacks in Node.js applications. For servers and applications, Node.js is a JavaScript-based runtime environment. Cloud functions or any other setup that supports Node.js would be able to host it on your cloud-based machine instance. Your program runs on the machine using Node.js, which interacts with the hardware. But all these processes must run smoothly if only you control rising theft with proper solutions. Let us understand it in detail-

SQL injections

A SQL injection occurs when users enter an SQL statement instead of their id or username, which could destroy your database. Authentication can be bypassed, your database can be retrieved, added, or modified by attackers.

Brute Force Attacks

Brute force attacks involve attackers who rely on automated software data over time. Your actions are stored on the website as cookies and Brute force easily identifies them. 

X-Powered-By header

A common non standard HTTP header is used to script languages. With the help of server and configuration techniques, one can disable or enable the HTTP response header. The developers may fail to disable the X-powered header that gives access to vital information. However, this header is used to reveal the technology in the app development and later on permit the attackers to exploit different security which is associated with the technology. 

Broken Access Control

Broken Access control enforces policies that specify the users to not act outside of their intended permissions. This usually results in unauthorized information disclosures due to failures. Moreover, there is the possibility of modifying or destroying all data or performing business functions without the user’s permission. Hackers always exploit vulnerabilities to gain access to web applications.

Solutions to control theft

Avoid errors

Well, the next list is error handling. You must consider a few things and don’t let the user know the details. The error contains information that you do not want to expose. Such as paths or libraries. The second step is to wrap routes with a catch clause so that Node.js does not crash when the error is caused by a request. As a result, attackers are prevented from finding malicious requests that will crash your application and send them repeatedly, resulting in the application constantly crashing. 

Avoid data leaks

Remember, do not trust the front end. The front, as well as what you send to it, shouldn’t be trusted. The front can filter what to display by sending all data for a specific object. The hidden data sent from the backend, however, is very easy for an attacker to get. Let’s take an example, if you show a list of users who register for any event then a SQL query is generated for all the users. The data are sent to the front end and hence you need to filter and show the first and last names. But you don’t need to show all the data as it is easily accessible via the browser developer Console which ultimately leads to data leaks.

Few developers consider Node.js to be a security threat as it lacks default errors caused by platform construction. But if you keep the above points in mind you can safely work with Node.js as it is an open-source environment. For a smooth and safe development process, you can easily hire Node Js Developer from the best resource. Today, there are many outsourcing companies available for Node.JS developers. Contact the one who can assure you of the security. 

Final lines

Over the years threats and security flaws have caused thousands of companies to breach the data. The sensitive data are compromised and leaked which cannot be priced in simple amounts. This block will surely help to understand the threat which hampers applications. However, you must follow the above practices that help you to consider security at every step of the development cycle.
