Why should I remove the Generator meta?

All Joomla! websites come by default with the following meta tag:

<meta name=”generator” content=”Joomla! – Open Source Content Management” />

Removing the Joomla! meta generator tag is one crucial aspect of protecting your website. The generator tag tells hackers that your website is built upon Joomla! framework. Then, once they figure out your Joomla! version, they know what vulnerabilities can be used to hack your website. That's why it is important to hide all the traces that may help the hackers to recognize known vulnerabilities.
