Comment (by tomjdevisser):

 For added security, I think it would be a nice addition to the theme to
 add the following code to each file in the theme:

 {{{#!php
 <?php
 <?php
 // Make sure no one can call this file directly
 defined( 'ABSPATH' ) or die;
 }}}

 Some more information on using this:

 abspath

 differences-between-wpinc-and-abspath

 PS: This is my first ticket, and I don't know exactly what
 focuses/type/keywords would fit. If anything needs changing, constructive
 feedback is highly appreciated.
