How do I keep my Joomla site secure?

Following that you need to keep your Joomla version, and all extensions up to date at all times and apply security patches as they are released, ensuring you have backups in place should you run into problems.

It's worth taking extra precautions, installing an SSL Certificate, along with extensions that provide additional security, and you should monitor the vulnerable extensions list on a regular basis, along with Joomla security bulletins.
