How can you check your Joomla! installation's overall security and health?
From Joomla! Documentation
- Use the free Joomla extension, Joomla! Tools Suite (JTS), which is a Joomla! environment audit, maintenance and diagnostic application written in PHP. The JTS suite of tools can diagnose, report and advise on common installation, health and security issues, including performing several common performance and recovery actions.
