The learning unit aims to explore some security issues arising from the massive spread of the cloud paradigm, smart/mobile, and IoT. These issues not only alongside aspects of technological security, but also "social" issues, as well as phenomena of "consumerization" and the user's habit of insecure behavior. Moreover, the technological evolution dynamic light always new phenomena (biometrics more usable, blockchain for payments and transactions, etc.) and consequently new risks and opportunities. The LU aims to provide a taxonomy of possible threats to the infrastructure, devices and applications, deepening methodological approaches, tools and organizational solutions for proper management of security in these areas.
