A Setting That Many CodeIgniter Developers Miss While Taking Their Code To Production

These two settings inside the index.php file should be changed to random strings. The folder names should also be changed to match as well.


/*
*---------------------------------------------------------------
* SYSTEM FOLDER NAME
*---------------------------------------------------------------
*
* This variable must contain the name of your "system" folder.
* Include the path if the folder is not in the same  directory
* as this file.
*
*/
$system_path = 'system';

/*
*---------------------------------------------------------------
* APPLICATION FOLDER NAME
*---------------------------------------------------------------
*
* If you want this front controller to use a different "application"
* folder then the default one you can set its name here. The folder
* can also be renamed or relocated anywhere on your server.  If
* you do, use a full server path. For more info please see the user guide:
* <a href="http://codeigniter.com/user_guide/general/managing_apps.html">http://codeigniter.com/user_guide/general/managing_apps.html</a>
*
* NO TRAILING SLASH!
*
*/
$application_folder = 'application';

You may be wondering to yourself: “why does it matter?”. It matters when you DO NOT want your application fingerprinted as a codeigniter application by a hacker. One of the first things some of these guys (or gals) do is run a directory fuzzer on your server. That fuzzer makes requests to your server through a list of common directory names. Believe me, the two terms ‘application’ and ‘system’ is early on in that list, I tried it.

Give a hacker as little information about the internals of your program as possible and make it a bit more secure.
