Say Goodbye to Your Apache Server Header – Here’s How
Greetings, dear reader. Are you looking for ways to improve your website’s security and protect it from potential attacks? If yes, then you have come to the right place! One of the essential steps towards securing your website is removing your Apache server header. In this article, we will discuss everything you need to know about removing your Apache server header, its advantages and disadvantages, and how to do it. So, let’s dive in!
What is an Apache Server Header?
Before we discuss how to remove your Apache server header, let’s first understand what it is. An Apache server header is a line of text that contains information about the server that is hosting your website. It typically includes the server software name, version number, and the operating system. It is visible to anyone who has access to your website’s source code and can easily be seen by potential attackers looking for vulnerabilities on your website.
While it might seem harmless to display this information, it can pose a severe security threat to your website. Hackers can use this information to exploit known vulnerabilities in your server software and operating system and gain unauthorized access to your website. That’s why it’s crucial to remove your Apache server header and keep your website secure.
How to Remove Your Apache Server Header
Removing your Apache server header is a simple process that can be achieved by tweaking some configuration files. Follow these steps:
Step 1: Locate Your Apache Configuration Files
The first step towards removing your Apache server header is to locate your Apache configuration files. Depending on your server’s operating system, the location of these files may vary. Generally, the files are located in the following directories:
Operating System |
Configuration File Location |
Ubuntu/Debian |
/etc/apache2/conf.d/security |
CentOS/Fedora/Red Hat |
/etc/httpd/conf/httpd.conf |
FreeBSD |
/usr/local/etc/apache24/httpd.conf |
Step 2: Open the Apache Configuration File
Once you have located your Apache configuration file, open it using your favorite text editor. You will need to have superuser privileges to edit this file.
Step 3: Find and Modify the “ServerTokens” Directive
The next step is to find the “ServerTokens” directive in your Apache configuration file and modify its value. The “ServerTokens” directive controls what information is displayed in your Apache server header. By default, it is set to “Full,” which displays detailed information about your server software and operating system. To remove your Apache server header, you need to set it to “Prod” or “ProductOnly.” Here’s how:
Find the following line in your Apache configuration file:
ServerTokens Full
Change it to:
ServerTokens Prod
Or:
ServerTokens ProductOnly
Save the changes and close the file.
Step 4: Restart Apache
Finally, restart your Apache server to apply the changes. Run the following command:
sudo service apache2 restart
Or:
sudo systemctl restart httpd
Congratulations! You have successfully removed your Apache server header.
