So you want to secure your WordPress installation from hackers? That’s quite a broad subject as there are many different types of hacking out there.
First of all, getting the right host is the most important. This not only effects the speed of your WordPress website, but also your security. If your host isn’t patching their servers or isn’t configuring their firewalls correctly, then your WordPRess website is not secure against hackers. I highly recommend Fast WP Hosting, they’re cheap, fast and secure.
Secondly, there are plugins you can get for WordPress security, such as Better WP Security that can secure your website or Limit Login Attempts, which protects you from brute force attacks.
Thirdly, you should ensure that you update WordPress so you’re always running the latest version.
Finally, you need to ensure that you install WordPress with the correct file and folder permissions.
These things should help to secure your WordPress website from hackers.
