Why Should Security Updates be Done On My Website Regularly?

If your website platform is a CMS such as Wordpress, Drupal or Joomla it consists of core files and contributed plugins or modules. The core files are the main files for your platform and the contributed ones are optional additions you are using to perform various functions that you require for your particular website. Routinely there are updates available for either the core files or these optional additions that will require updates. Some might just have improved code modifications and some will be security updates.
