Nowadays one of the most renowned free and open-source platforms for web content and user communities is Drupal. It is used in various spheres of our life, e.g. politics (the White House), art (Louvre), education (University of Oxford) etc. Though fame is a pretty nice thing, sometimes it brings not only success, but also troubles. And Drupal can prove it, as due to this fact all Drupal powered websites have become victims of hackers trying to break them. For this reason I find it rather important to inform you how to protect Drupal sites.
