The Node Version Manager (NVM) provides a simple way to manage multiple versions of Node.JS on a single system. This is incredibly useful for testing scripts or programs with multiple Node.JS versions. With NVM, you can easily switch between versions of Node.JS to find the one that works best for you. To get started, check out the comprehensive procedure for working with NVM here.
Keep Your Node.JS Apps Secure: Learn How To Keep Your Data Safe!
Despite its powerful scripting engine, Node.JS can present an open invitation to hackers if not installed properly. To make your instance of Node.JS more secure, here are some basic steps to follow: firstly, always patch your system to ensure the latest security updates; secondly, configure your server with appropriate security settings; and thirdly, monitor your system for suspicious activity. By following these steps, you can ensure a secure and safe environment for your Node.JS instance.
- Conversely, it is strongly recommended not to run Node.JS as the root user, as this would provide a hacker with access to the entire system if they were to gain access. Instead, run Node.JS with only the permissions necessary for the particular application, thus limiting the potential damage that could be done.
- Strong authentication is the first line of defense against hackers for any application. It is best practice to use a tool such as Okta or OAuth for authentication, in order to securely authenticate users and protect your application. Furthermore, these tools provide an added layer of security, making it harder for hackers to gain access to your application.
- Using a reverse proxy is a great way to ensure the security and reliability of a Node.JS application, as it allows for the limitation of incoming requests. Specifically, the reverse proxy receives the user’s request and vets it to make sure it is valid before forwarding it to the Node.JS application. Thus, the reverse proxy acts as a buffer, allowing for increased safety and assurance when using Node.JS applications.
- Using a package manager such as NPM is essential for controlling access to packages and how they can be used. NPM offers a wide range of commands to set package access levels, ensuring that only authorized users have access to the packages they need.
- Node.JS is prone to injection-based attacks, so it is absolutely necessary to confirm that the user is sending data, rather than an executable script. To do this, it is important to validate user inputs.
- Keeping secrets secret is an essential aspect of security. Storing sensitive information such as database connection strings and API keys in code should be avoided, as it can be easily exposed. Fortunately, a specially configured library like dotenv can offer a secure alternative – it enables environment variables to be loaded and stored in a safe manner.
- Error messages should be kept generic. Instead of giving too much information away, such as “Password Invalid,” use “Invalid Input” instead. This conveys enough information for the user to make a correction, while also ensuring that the hacker is not given any clues as to what the valid name or password might be. Therefore, it reduces the amount of work the hacker has to do in order to gain access to the system.
- Adding HTTP response headers can provide added security for users, as it forces their browser to rely on strict transport security, display content in frames, and prevent changes to Multipurpose Internet Mail Extensions (MIME) type. Therefore, it is essential for web developers to consider implementing these headers in order to ensure their sites are secure and protected.
- Maintaining server-side logs and monitoring them is essential for administrators to keep track of their servers. Although it may seem like overkill, it can uncover any patterns in transactions, which could alert administrators to potential hacker activity. Consequently, server-side logging and monitoring is a critical step for protecting a site from malicious activity.
- Using a security linter is an essential part to improving code, as it looks for security issues in code. It helps to locate the majority of security issues, however, there is no guarantee that a hacker won’t find another means of accessing the code. Therefore, it is recommended to use other methods to secure the application as well.
