Turn Off Apache Server Signature

Say Goodbye to Apache Server Signature and Secure Your Website

Welcome to our comprehensive guide on how to turn off Apache server signature. If you own a website or blog, then you are probably familiar with Apache, the most popular web server software in the world. Apache provides exceptional performance, stability, and flexibility, but by default, it also sends a server signature that reveals information about your server software and operating system. This information can be exploited by hackers and other malicious actors who may use it to launch attacks against your website or server. In this article, we will explain in detail what the Apache server signature is, how it works, and the benefits and drawbacks of turning it off.

What Is Apache Server Signature?

Apache server signature is a line of text that contains information about the version of Apache server software and the operating system running on a web server. It is sent in the HTTP header of every request that the server receives and is usually visible in the server response page. The server signature can be used by hackers and attackers to exploit vulnerabilities and launch attacks on the server.

How Does Apache Server Signature Work?

The Apache server signature is enabled by default, and it is sent in the HTTP response header of every request that the server receives. The server signature consists of three parts: the server name, the server version, and the operating system. For example, a typical Apache server signature looks like this:

Server Signature
Apache/2.4.6 (CentOS) OpenSSL/1.0.2k-fips mod_fcgid/2.3.9 PHP/5.4.16

Advantages and Disadvantages of Turning off Apache Server Signature

Turning off Apache server signature can improve the security of your website and server by making it more difficult for hackers and attackers to launch targeted attacks against your system. However, it can also have some drawbacks that you should be aware of before making the decision to disable the server signature.

Advantages of Turning off Apache Server Signature

There are several advantages to turning off Apache server signature, some of which include:

Increased Security

One of the main advantages of turning off the Apache server signature is that it can significantly improve the security of your website and server. By hiding the server signature, you make it more difficult for attackers to exploit known vulnerabilities in the server software and operating system.

Reduced Server Load

By turning off the server signature, you can also reduce the server load and improve the performance of your website. This is because the server signature adds extra bytes to the HTTP response header, which can increase the file size and slow down the page load time.

Disadvantages of Turning off Apache Server Signature

However, turning off the Apache server signature also has some drawbacks that you should consider before making the decision. Some of these drawbacks include:

Difficult to Identify Server Issues

By turning off the server signature, it becomes more difficult to identify server issues and troubleshoot problems that may occur. This is because the server signature provides valuable information about the server software and operating system, which can help diagnose problems and find solutions.

Incompatibility with Some Applications

Some applications and software may require the server signature to function properly. Turning off the server signature may cause compatibility issues with these applications, resulting in errors or malfunction.

How to Turn off Apache Server Signature

Now that you understand the benefits and drawbacks of turning off Apache server signature, you may be wondering how to disable it. Fortunately, the process is straightforward and can be done in a few simple steps.

Step 1: Locate the httpd.conf File

The first step in disabling the server signature is to locate the httpd.conf file on your server. This file contains the Apache configuration settings and is usually located in the /etc/httpd/ or /etc/apache2/ directory, depending on your system.

Step 2: Edit the httpd.conf File

Once you have located the httpd.conf file, open it using a text editor such as vi or nano. Then, add the following lines of code at the end of the file:

ServerSignature Off

ServerTokens Prod

These lines will turn off the server signature and change the server tokens to “Prod”, which will hide the server software version. Save the file and exit the text editor.

Step 3: Restart Apache

The final step is to restart the Apache service to apply the changes. You can do this by running the following command in the terminal:

sudo systemctl restart httpd
