The purpose of this study is to treat aspects that are related to the sensitivity of data, information and knowledge transmitted through Internet of Things, helping all people interested in these new ICT technologies to become aware of some ethical issues. In this new media, which is no more in its infancy, the vulnerabilities and attacks are various, caused by technological advances and proliferated through lack of users’ awareness. This warning message is needed because of data, information and knowledge transfer from virtual to physical devices that are connected to wireless networks of different sizes and importance. The transfer is augmented by the extended use of new technologies as RFID, NFC, sensors, 3G and 4G and brings along the adjustment of the traditional information security threats to this new environment, as well as the emergence of new characteristic dangers. The problems treated here are of interest both for each of us, as individuals, and for the organizations managers – especially in a world in which the borderline between the physical and virtual life is becoming more and more difficult to draw.
