Today, cyber threats are all over the internet. And the same as the other frameworks, Node.js also demands some security measures, especially in its third-party packages. The matter is that by default, NodeJS is not that secure as it should be. Maybe this is why Node.js Development Companies are puzzling with it even in 2021.
The situation made us write a guide on Node.js security. Yes, there are not all the solutions present here but workable and specific. In this article, we will go deep into the Node.js framework (Most Vulnerable) and the keys to secure doors.
Let’s get started with the roots.
Why Node.js Projects Face Security Risks?
The open-source app often comes with inherent and licensing issues along with their open source components. And the worst thing is, even the security testing tools (dynamic and static code) can’t effectively detect the vulnerabilities.
In the case of Node.js, you have to manage the package manager index first and then describe the dependency. While doing this, keep in mind that index files do not include reused open source components.
While performing NodeJS development, open-source communities often reuse open source projects to boost it. However, it also decreases the time to market and combines functionality.
Top NodeJS Security Risks and Solutions
The security issues in Node.js can gunpoint you in front of attacks such as code injection.
- Old Versions Such as Express – Make sure you are not using any old application framework of NodeJS. Especially, if you’re using a version like express (consider the update one). The HTTP headers of Node.js can help you but can hurt you too.
Choose Helmet over Express / connects, as it improves the security of HTTP headers by adding/removing various from them. It also saves your site from man-in-the-middle attacks, enforcing secure server connection and cross-site scripting attacks. If possible, go for Node.js Development Services to help you out.
- XSS (Cross-site scripting) – Accept it, not all the programmers are the experts. XSS secures your site to inject malicious client-side scripts into websites, as they can be responsible for the data leaks.
To cover this up, you can use Retire.js as a tool and scans Node for vulnerabilities. You can use many techniques such as output encoding or tools with built-in encoding frameworks. You can also hire Node.js developers to secure your site with the issue.
- CSFR (Cross-site Forgery Request)- In CSRF attack the end-users and make them take necessary actions. For this, hackers can trap users and do it by social engineering techniques such as chat or email sending links. It ultimately can make you lose your funds.
For prevention, we suggest you go for an Anti-Forgery Tokens, which is a hidden HTML input. And can be rendered for you to avoid the attacks. This will compare or monitor the value that is exchanged by the server to clients and developers.
- Default Session Name- The session cookies started monitoring your activity on sites especially, the e-commerces one. These are responsible to identify users and their actions. And while shopping, the cookies remember your selected items and make a shopping cart to have these items, while checking out.
If you use default cookie names, it increases the risk that hackers threaten your app. So it will be helpful if you use one of the middleware cookies sessions such as express-session.
- X-powered by Header- It is one of the standard HTTP response headers. But some technologies include this response by default. However, servers can change or disable it to prevent hackers.
It will be great if you disable the header and hide information from hackers or more you consult a NodeJS development company for better guidance.
For more, you must check for the vulnerabilities from time to time, beware of the child process module, ignore running code with Sudo, etc.
