In this tutorial, we will show you how to hide PHP version in Linux server. In default Apache/PHP configuration, the server sends HTTP Header with the information of which PHP version is running on the server. The HTTP response header “X-Powered-By” displays the version of PHP that is running on the server. This information can be used by an attacker to try to exploit any vulnerabilities in the PHP version you are running, specially if you are running an older version with known vulnerabilities.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation hide PHP version information in the header on a Linux server.
