A Content Management System (CMS) like Joomla!, is very powerful, and together with the over 7,000 Extension for it, can be used to build any type of web site.
Security becomes an issue when the CMS or the installed extensions are not kept up to date. This can result in the web site getting hacked, defaced, spam links inserted, or the site being used for phishing attempts (to steal people's bank details).
