The exponential growth of the number of IoT devices in the last years will increase the number of attacks perpetrated against IoT devices, since more IoT devices will be used to carry out illegal activities on the Internet. An example may be Mirai, a botnet composed of 200.000 and 300.000 infections with a peak of 600.000 infected devices, mainly routers and cameras. In 2016 it was able to launch DDoS attacks against Krebs on Security and Deutsche Telekom leaving 900.000 Germans offline. This poses a great threat for all the systems and infrastructures connected to Internet since they may be of vital importance for human daily activities.
