architecture and security problems of IOT

Internet of Things (IoT) are everywhere in our daily life. They are used in our homes, in hospitals, deployed outside to control and report the changes in environment, prevent fires, and many more beneficial functionality. However, all those benefits can come of huge risks of privacy loss and security issues. To secure the IoT devices, many research works have been conducted to countermeasure those problems and find a better way to eliminate those risks, or at least minimize their effects on the user’s privacy and security requirements. The survey consists of four segments. The firs segmen presents the IOT architecture. The second one will explore the most relevant limitations of IoT devices and their solutions. The third one will present the classification of IoT attacks. The last segment will focus on the mechanisms and architectures for authentication.
