WordPress security is no joke! This applies to all websites. Besides comments spam, imagine getting hacked and not being able to access your WordPress site, or that someone changes your site or adds hidden links to other sites, or that you entire site gets destroyed, or what about people accessing your hosting account and emailing spam message or installing malware on your hosting?
If you think that is rare or not something you need to be concered about… think again! I was thought the same thing until I started ranking in the search engines and getting my WordPress site hacked or its integrity compromized. The good thing is that WordPress security is relatively easy… though necessary part of runing any type of website. So make sure to pay attention to this section of the training so that you can effectively protect your website and more.
