Choosing WordPress to power your site means WordPress is the foundation of everything on your site. The fact that it is free and open source carries many benefits. But with each update, the exploits of the previous version are made available to the public making previous versions more susceptible to being hacked. Employing backs security through obscurity tactics, you can remove or hide the version number of your WordPress installation from displaying. You can even choose a more simple solution with plugins to hide the version number. This may deter a bot from attaching to your site, but this does not patch holes in older versions of WordPress. Only updating your WordPress installation as newer versions are made available will remove the published exploits.
Updating WordPress is simple (since version 3.7 was released with automatic updates)
In previous versions of WordPress a new version banner would display in your dashboard whenever there is an update available. Now WordPress installs will automatically update to new minor versions without you having to lift a finger. Minor versions are usually for security updates. You will, however, still need to update for to new major versions.
To update WordPress
- First things first! Backup your WordPress.
The biggest threat to your site
The quickest way to compromise your site includes adding poorly, maliciously coded or out of date themes or plugins from untrusted developers or sites. Due to the open source nature of WordPress many themes or plugins are distributed under a GPL or GPN (General Public License) licenses. So its easy for themes and plugins to be forked and redistributed on free WordPress theme and plugin sites with the addition of hidden or malicious code. This code can be as simple as exposing a virus or as serious as exposing your visitors to identity theft.
Before downloading a free theme or plugin:
- Research the author and only download from the authors site or the WordPress depository
- Ask advise at WordPress.org/support
- If you are going to use free trusted plugins or themes, check the version number compatibility listing and verify that the plugin or theme is still being supported and updated. Many themes or plugins are slow to receive updates or are simply abandoned.
- If you don’t use it, lose it. If you are not using a theme or plugin, delete it.
- Use paid supported themes and plugins (not free).
Experience shows that nearly all WordPress attacks could be defended against and defended by simply using safe, up to date and trusted plugins and themes.
