A CMS (acronym for content management system) is a software application running on the web that allows, with simple screens, the insertion, modification and updating of textual and graphic content of a web page and/or an entire website.
In order to achieve proper functioning of the CMS and secure use, it must be kept up-to-date. The risks arising from failure to update the CMS are many and can be summarised as follows:
Sudden site crash. If an automatic backup system was not provided, there will be no possibility of restoring the site, which will be lost forever.
Data and credentials theft, with easily imaginable consequences.
Defacing of the site, i.e. replacement of the main page with a malicious page created by the attacker.
Final deletion of the database, resulting in the loss of all site content. If no backups were present, the deletion will be definitive.
Insertion of unwanted advertising, making surfing annoying and dangerous and running the real risk of seeing one's domain end up on a dreaded blacklist. We talked about blacklisting in this article.
