Top Tips for Securing WordPress Installations
An out-of-the-box WordPress installation is not very secure. The tool is great for blogging but, unfortunately, an easy target for the unscrupulous to hack your site.
The result of being hacked could be anything from changed &/or deleted content (obvious when you look at the site) to subtle things such as putting links to other sites that you can’t even see. These links sound harmless but if these sites are “undesirable” this can get your site blocked by browsers and severly penalised by search engines. The best approach is to make your site difficult to hack and therefore not worth their time.
