Joomla optimization and Joomla optimization and securitysecurityMost SQL injections that are

written to hack a Joomla! website, try to retrieve data from the jos_users table. This way, they can retrieve the username and password from the super administrator of the website. Changing the default prefix into something random, will prevent (most / all) SQL injections.

Joomla optimization and Joomla optimization and securitysecurityWe can set the database prefix

when installing our Joomla! website. If we already installed Joomla! and want to change our prefix we can use global configuration settings in admin side
