As a network, which consists of objects communicating with each other through internet technology, Internet of Things (IoT) is considered as an important data source. Through the means of Internet of Things (IoT), not only can data be shared, but also connection to all devices is possible for improving quality, of life, and creating new services and applications. IoT allows various devices and objects to be addressed, and can also recognize and locate such devices. The use of this web, on which objects are interconnected, implies certain ethical issues. Apart from the beneficial intended uses of IoT as part of the process of digitalization, such uses introduce various challenges such as privacy violations, disrespect to privacy, and construction of surveillance society. These challenges must be addressed as a priority, and IoT products and services must be built upon security and privacy. Based on this perspective, the study aims to draw attention to the use of IoT technologies with an ethical approach, and discuss issues related to surveillance, information security, and privacy. The study is important in terms of investigating the threats and solution suggestions within the scope of the use of IoT technology. As a result of the study, it was determined that a flexible approach must be adopted according to the situation since privacy and transparency, and confidentiality and surveillance cannot exist together. It was observed that the responsibilities on the security issue must be shared between providers of IoT device and the users. It was concluded that awareness of the users of IoT devices must be raised on privacy and security.
