Nginx Tip - Set up a server tokens configuration with server_tokens

Nginx is a popular web server software known for its high performance, scalability, and flexibility. It is widely used by many websites and hosting providers, including Server.HK, to deliver content efficiently. One of the essential features of Nginx is the ability to configure server tokens, which provide information about the server software version. In this article, we will explore how to set up a server tokens configuration with server_tokens in Nginx.

What are server tokens?

Server tokens are pieces of information that web servers include in their responses to identify the software version running on the server. These tokens can reveal valuable information to potential attackers, such as the server software, version, and even the operating system. By default, Nginx includes server tokens in its responses, which can be a security risk.

Why should you hide server tokens?

Hiding server tokens is an essential security practice to protect your server from potential attacks. By revealing the server software and version, attackers can exploit known vulnerabilities specific to that version. Hiding server tokens adds an extra layer of security by making it harder for attackers to identify potential vulnerabilities.

How to set up a server tokens configuration with server_tokens in Nginx

To hide server tokens in Nginx, you need to modify the Nginx configuration file. Here's how you can do it:

  1. Open the Nginx configuration file using a text editor. The file is usually located at /etc/nginx/nginx.conf or /etc/nginx/conf.d/default.conf.
  2. Locate the http block in the configuration file.
  3. Add the following line inside the http block:
server_tokens off;

This configuration directive tells Nginx to turn off the server tokens and not include them in the server responses.

  1. Save the configuration file and exit the text editor.
  2. Restart Nginx to apply the changes. You can do this by running the following command:
sudo service nginx restart

After restarting Nginx, the server tokens will no longer be included in the server responses.

Conclusion

Hiding server tokens is an essential security practice to protect your server from potential attacks. By following the steps outlined in this article, you can easily set up a server tokens configuration with server_tokens in Nginx. Remember to always keep your server software up to date and follow other security best practices to ensure the safety of your server.

Summary

In conclusion, setting up a server tokens configuration with server_tokens in Nginx is a crucial step in enhancing the security of your server. By hiding server tokens, you can prevent potential attackers from identifying vulnerabilities specific to your server software version.
