Wordpress, apart from being a very popular and widely used CMS, is very vulnerable to hacking attacks in it's out of the box state. Also because of it's popularity and the fact that it is open source, it is prone to security holes. So if you have website based on wordpress, chances are it is open for hackers and script kiddies to attack and take over your website.
So securing and hardening your wordpress installation is the first thing you should do (even before going live if possible).
