Activate security on your site!
Even if you have just got your site up or just wrote one blog – set up your security.
Otherwise you will end up installing it later and spending time fixing things that the security plug in would have fixed.
I had installed a free version of a plug in, but hackers still go through so I upgraded to the paid version.
This week, I searched for way to fix things and also found this blog post with a list of recommended Security Plugins.
It has a lot of great information in it to help you plan for protections for your site.
I would recommend going with the paid version of the software to have less headaches in the future.
Hope this helps you avoid some pitfalls.
