An Introduction to Nginx Server Header Removal

Welcome to our guide on how to completely remove the server header on an Nginx web server.

In this article, we will discuss the advantages and disadvantages of this process, as well as provide you with a step-by-step guide on how to remove server headers in Nginx.

What is a Server Header?

A server header is a piece of information that is sent from your web server to a user’s browser. This information includes the type of web server being used, as well as other technical details that can be used by hackers to exploit vulnerabilities in your website. Therefore, removing server headers is important for improving website security.

Why Remove Server Headers in Nginx?

Nginx is a popular web server used by many website owners around the world. However, by default, it sends a server header in its HTTP response, which includes information about the Nginx version being used. This information can be used by hackers to identify vulnerabilities in your website and launch attacks. By removing the server header, you can make it more difficult for hackers to identify your web server and exploit vulnerabilities.

How to Remove Server Headers in Nginx

Removing the server header in Nginx is a straightforward process that can be completed in a few simple steps. Here’s how to do it:

Step 1: Edit the Nginx Configuration File

The first step is to open the Nginx configuration file, which is typically located in the /etc/nginx/ directory. You can edit the file using a text editor like Nano or Vim.

Step 2: Add the Appropriate Configuration

To remove the server header, you need to add the following configuration in your Nginx configuration file:

server_tokens off;

This configuration will turn off Nginx’s server token, which is responsible for sending the server header.

Step 3: Save the Configuration File

After adding the configuration, save the file and exit the text editor.

Step 4: Restart Nginx

Finally, restart the Nginx server to apply the changes:

sudo service nginx restart
