Tips to protect your web site:
1. Keep contact with your web hosting provider, so they can help you out if there is a hacking.
2. Don’t give your username/password to anyone else.
3. Change your password frequently.
4. Disable the “Forgot Password” on your site. This function is convenient but it gives a chance for hackers to play with.
5. Keep third party components in your website update, likes Forum, Online Chat, etc.
