Many look to 2020 as the beginning of a planetary awareness that removes cybersecurity from the list of facade priorities of each company, to make it, instead, an integral part of daily life. Every year the reports of various research centers, more or less specialized, repeat like a mantra that spending in the IT world will grow, breaking through the psychological threshold of yet another trillion dollars. It is a fact that the number of successful attacks, of any kind, increases every year and with it increases the cost for companies to repair the damage. Despite the alarming data, more than half of the companies, and not only the Italian ones, are convinced that their network and data are not an object of interest for computer piracy and therefore no special measures are required. Far from representing the magic potion that solves everything, this book aims to increase the level of knowledge of the mechanisms that guide the action of computer piracy, showing the weak parts to be reinforced and the potential risks.
