Introduction
Greetings, fellow web developers and server administrators! Today, we will be discussing Apache Error Remove Server Version and its impact on website security and search engine optimization. As you may know, Apache is a widely used web server software that powers over 40% of the internet. However, it also has a potential security vulnerability that can reveal sensitive information about your server and website to potential attackers.
This vulnerability is the Apache server version, which is revealed in the server header response. Attackers can use this information to exploit known vulnerabilities and attack your website. Additionally, Google and other search engines use this information to determine the credibility of your website, which can affect your search engine rankings. In this article, we will discuss what Apache Error Remove Server Version is, its advantages and disadvantages, and how to implement it on your server.
What is Apache Error Remove Server Version?
Apache Error Remove Server Version is a security measure that removes the server version information from the server header response. This means that when a user requests a webpage from your server, the server header response will not reveal the Apache server version. Instead, it will only display the server software name.
Why is Apache Server Version Information a Security Risk?
Apache server version information is a security risk because it reveals the software version and other sensitive information about your server. Attackers can use this information to exploit known vulnerabilities in the software and gain unauthorized access to your server.
For example, if your Apache server is running on an outdated software version with known vulnerabilities, attackers can use this information to exploit those vulnerabilities and gain unauthorized access to your server. Additionally, attackers can use this information to craft targeted attacks that are specific to your server’s software version.
How Does Apache Error Remove Server Version Work?
Apache Error Remove Server Version works by modifying the server header response to remove the server version information. Instead of displaying the full server version information, it only displays the server software name. This makes it more difficult for attackers to determine the software version and other sensitive information about your server.

How to Implement Apache Error Remove Server Version
Implementing Apache Error Remove Server Version is a simple process. Here’s how:
Step 1: Edit Apache Configuration File
First, you need to edit the Apache configuration file. Depending on your server setup, the file may be located at /etc/httpd/conf/httpd.conf or /etc/apache2/apache2.conf. Open the file in your text editor of choice.
Step 2: Add ServerTokens Directive
Next, you need to add the ServerTokens directive to the configuration file. This directive controls the amount of information that is displayed in the server header response. The default value is Full, which displays the server software name and version information. To remove the version information, change the directive to Prod.
ServerTokens Prod
Step 3: Add ServerSignature Directive
You also need to add the ServerSignature directive to the configuration file. This directive controls whether the server signature is displayed in the server header response. The default value is On, which displays the server signature. To disable the server signature, change the directive to Off.
ServerSignature Off
Step 4: Save and Restart Apache
Save the configuration file and restart Apache to apply the changes:
sudo service httpd restart
