Remove the default index.php

In web development, many websites have a default homepage file, which is usually called index.php. Sometimes, you may want to remove this default file because it may leak sensitive information and make your website more vulnerable. In this article, we will explain how to remove the default index.php file.

Why should we remove the default index.php file?

On many web servers, index.php is the default home page file. When you access a directory without a specific file name, the server automatically directs you to this file. For most developers, this is a convenient feature. However, this file may also make your website more vulnerable.

Why is this? Because due to incorrect configuration or code vulnerabilities, attackers may exploit vulnerabilities in the index.php file to obtain sensitive information or execute malicious code. Therefore, for those websites that involve sensitive information, we should remove the default index.php file to reduce the risk of being attacked.

How to remove the default index.php file

The following is how to remove the default index.php file:

1. Rename the index.php file

First, you can rename the index.php file, for example, change it to index_backup.php. This way when the HTTP request reaches the server it does not go to the index.php file but ignores it and goes to the next available file. This solution is very simple, you only need to change the file name, and it is suitable for most websites.

2. Disable index.php through .htaccess file

.htaccess is a configuration file on the Apache server, which can be used to specify server parameters and rules. You can specify not to use index.php in the .htaccess file. The specific steps are as follows:

First, you need to access the root directory of the website, which is often called the "website root directory".

Secondly, you need to find a file named ".htaccess" or create one yourself. On a Windows system, you can create this file using Notepad, name it ".htaccess" and set the file type to "All Files". On a Linux or Mac system, you can create this file using Terminal.

In the .htaccess file, add the following code:

DirectoryIndex home.html index.php

Change it to:

DirectoryIndex home.html

In this way, when you access a directory without a specific file, the server Will forward the request to the home.html file instead of the index.php file.

It should be noted that if your website uses other home page files, you need to specify the name of this file in the above code.

3. Disable index.php through the website backend

Some website backends also provide options to disable the index.php file. The specific steps will vary depending on the website backend. If you are using WordPress, you can find the "Permalinks" option in the "Settings" option and modify it to a non-default value.

In web development, many websites have a default homepage file, usually called index.php. While this file is convenient for developers, it may also make your site more vulnerable to attacks. Therefore, we should consider removing the default index.php file to reduce risks.
