Disabling Website Directory Browsing

Sharing is caring!

The world wide web has hit Zimbabwe like a pandemic. Almost everyone and even companies have registered their online presences, either on a website or on social platforms. But Cyber security has become some what a foreign language to most, even the Mobile Network Operators (MNOs).

Website Directory Index Vulnerability simply means that if somebody goes to a directory that does not have an index file, they will see a listing of all files in that directory. If the directory contains nothing but publicly-accessible files (such as pictures, PDFs, HTML files, or what-have-you), then the auto-generated index is no less secure than an equivalent manually-generated index.

However if that directory contains scripts written in PHP or ASP or ASP.NET or a other languages where the application files are stored inside the document root mixed in with the media then the auto-generated index may deliver links to files that you didn’t expect to make public. This is even truer if you have “include” files in there as well.

This can be done from within your FTP program itself. If .htaccess exists, download it to your computer.

Create or Open the .htaccess File

If you’ve managed to get the .htaccess file, open it in an Notepad++ text editor (like Notepad). If one does not exist, use the editor to create a new blank document. The rest of this article will assume that you have already started the editor with the .htaccess open or with a blank document if no .htaccess file previously existed.

WARNING: do not use a word processor like Word, Office, or WordPad to create or edit your .htaccess file. If you do, your site will without explanation fail to work when you upload the file to your web server. This is very important. There are no exceptions.
