Hello SIr, Joomla, Wordpress or any other open source software is easy to secure by the following steps: 1) host your site in a VPS or Dedicated environment 2) create .htacess file in admin area to avoid other IP address to access server 3) update server + Joomla package. If you need help with that you can contact me. Or you can do it your self if you understand what i am saying :) goodluck and greetings from The Netherlands.
