Hide Server Header Nginx: Blocking Sensitive Information from Hackers

Introduction

Hello there, dear readers! In today’s digital age, websites are prone to attacks from hackers. One of the most common security vulnerabilities is the server header information. This information contains sensitive data that hackers can use to exploit your website’s weaknesses. One way to protect your website is by hiding the server header Nginx. In this article, we will discuss what it is, why you should do it, its advantages and disadvantages, FAQs, and more.

What is a Server Header?

A server header is an HTTP response header that shows what server software the website is using. It contains sensitive information such as the server type, version, and operating system. This information is public and can be seen by anyone who inspects the HTTP response headers.

For example, if your website uses Apache, the server header will look like this:

Header Name	Header Value
Server	Apache/2.4.29 (Ubuntu)

Why Hide Server Header Nginx?

By hiding the server header Nginx, you are blocking hackers from obtaining sensitive information about your website server. This is crucial because it prevents attackers from identifying vulnerabilities in your website software. It also gives the impression that your website is more secure than it actually is.

Moreover, hiding the server header Nginx can improve your website’s SEO score. It prevents competitors from knowing what technologies you are using, giving you a competitive edge. It also hides the fact that you are using older technologies, which can negatively impact your SEO ranking.

How to Hide Server Header Nginx

To hide the server header Nginx, you need to modify the Nginx configuration file. Follow these steps:

1. Open the file /etc/nginx/nginx.conf
2. Look for the line that starts with “server_tokens”.

4. If it is present, change “on” to “off”.
5. Save the file and restart Nginx.

Once you have done this, the server header Nginx will be hidden, and your website will be more secure.
