Hide Apache Server Header: Why It Matters and How to Do It

Protect Your Website from Cyber Threats and Enhance Your Security with This Simple Step

Greetings, dear readers. In today’s digital age, website security is of utmost importance. With the rise of cyber threats and attacks, it’s crucial to take every possible step to protect your website from potential harm. One such step is hiding your Apache server header.

What Is Apache Server Header?

Before we dive into the details of hiding your Apache server header, let’s define what it is. Apache is an open-source web server software that is widely used around the world. When a web server serves a page, it usually sends some information along with it, such as the type of software it’s using to serve the page, which is called the Apache server header.

For example, if you open the developer tools on your browser and check the headers of a page, you’ll see something like this:

HTTP/1.1 200 OK
Date: Thu, 01 Jul 2021 00:00:00 GMT
Server: Apache/2.4.46 (Ubuntu)
Last-Modified: Wed, 30 Jun 2021 23:59:59 GMT
ETag: “abcd1234efgh5678”
Content-Length: 1234
Content-Type: text/html; charset=utf-8
Cache-Control: max-age=3600

In this example, “Server: Apache/2.4.46 (Ubuntu)” is the Apache server header. While it may seem harmless, it can actually reveal valuable information to potential attackers.

Why Should You Hide Your Apache Server Header?

Now that we know what the Apache server header is, let’s talk about why you should consider hiding it. There are several reasons:

Increased Security

As mentioned earlier, the Apache server header can provide valuable information to attackers, such as the version of Apache you’re using and the operating system it’s running on. This information can be used to launch targeted attacks on your website.

Less Information Leakage

By hiding your Apache server header, you can reduce the amount of information that is leaked to potential attackers. While it may not completely eliminate the risk of attacks, it can make it more difficult for attackers to gather the information they need to carry out an attack.

Compliance with Security Standards

In some industries, such as finance and healthcare, there are strict regulations and standards that require websites to hide their server information. By hiding your Apache server header, you can ensure that your website is compliant with these standards.

How to Hide Your Apache Server Header

Now that you understand the importance of hiding your Apache server header, let’s talk about how to do it. There are several methods you can use:

Method 1: Using the ServerTokens Directive

The easiest way to hide your Apache server header is by using the ServerTokens directive in your Apache configuration file. This directive allows you to set the level of detail that is included in the server header.

To use this method, follow these steps:

  1. Open your Apache configuration file. This file is usually located at /etc/httpd/conf/httpd.conf or /etc/apache2/apache2.conf, depending on your operating system.
  2. Search for the ServerTokens directive. If it doesn’t exist, add it to the file.
  3. Set the value of the ServerTokens directive to “Prod” or “ProductOnly”. This will remove all version information from the server header.
  4. Save the file and restart Apache.

Method 2: Using the ServerSignature Directive

Another method to hide your Apache server header is by using the ServerSignature directive. This directive controls whether or not Apache includes its server signature in the error messages it generates.

To use this method, follow these steps:

  1. Open your Apache configuration file.
  2. Search for the ServerSignature directive. If it doesn’t exist, add it to the file.
  3. Set the value of the ServerSignature directive to “Off”. This will prevent Apache from including its server signature in error messages.
  4. Save the file and restart Apache.

Method 3: Using a Third-Party Module

If you’re not comfortable editing your Apache configuration file, you can also use a third-party module to hide your server header. One such module is mod_headers.

To use this module, follow these steps:

  1. Install the mod_headers module on your server.
  2. Add the following line to your Apache configuration file to remove the server header:
  3. Header unset Server

  4. Save the file and restart Apache.
