There are a few things you should be aware of with your website, this list is by no means complete but should act as a starting point.
1. Make sure you use strong passwords, this is especially important for cPanel and FTP. The password you are sent when the account is created will be strong, this means it's hard to break. As tempting as it is to use an easy password that you can remember it may leave your website open for someone else to get in to. A strong password should be over 7 characters long and made up of a mixture of letters, numbers and special characters such as !"£$%^&*. cPanel has it's own password generator which generates passwords and tells you how strong it is, the generator is available whenever you create a user for email, FTP, databases etc.
2. If you use a Content Management System (CMS) like Joomla, PHP-Nuke or e107 make sure you regularly check for updates, the updates will likely include security fixes for known vulnerabilities in the CMS so updating is strongly recommended.
3. Keep regular backups, if something happens to your website is your responsibility to keep a backup. This includes both the files and any databases. We will help you restore your website but you shouldn't rely on us having a copy of your website. On cPanel there is an option to generate a backup of your site, you can choose to backup the files, the databases or everything and store them on your computer. The most important item to backup for CMS systems is the database, we recommend keeping at least weekly backups of databases and monthly of files.
4. Never chmod files/folders to 777 unless absolutely necessary, folders should be 755 and files should be 644. Configuration files should be the lowest value at which your site still works properly e.g. 600 or 400
