WordPress Security

A few of the more obvious steps that you can do to make your WordPress site more secure includes the following:

• Make sure that you have the most up to date WordPress installation as well as having all your plugins updated.
• Delete the admin username. By keeping the admin username, you're making it that much easier for hackers to gain access to your website as you're saving giving them half of the information needed to gain access to your blog, saving them time on hacking your site as now all they'll need to do is figure out the password. 
• Choose a password that's difficult to crack The password that you choose should be at least each characters and comprised of upper and lowercase letters as well as numbers and specials characters. 
• Protect your WordPress using .htaccess which is a configuration file allowing you to override your server's global settings for the directory that it's installed in. Here's a great article with a few suggestions on snippets of code that you can add to your .htacess file.

Take a look at the infographic below from WordPress Templates, that shows statistics of how many WordPress sites have been hacked over the past few years as well as some steps you can take (in addition to what was mentioned above) about protecting your site. Additionally, you should make sure to regularly backup your database, that way you have peace of mind in case anything does ever happen to your website.
