A Layered Taxonomy of Internet of Things Attacks

Internet of Things (IoT) is heavily affecting our daily lives in many domains, ranging from tiny wearable devices to large industrial systems. However, ensuring the security of IoT systems is really challenging due to the heterogeneous nature of the IoT environments. IoT has experienced unprecedented attacks that target not only businesses but also have a probability of endangering human lives. Therefore, providing a comprehensive classification of IoT attacks and the available defenses against them is of great importance. In this paper, we conduct a survey of IoT security attacks and provide a taxonomy to classify them based on different aspects. This comprehensive survey would be helpful for industry and academic researchers working to design secure IoT systems by analyzing which attacks have been investigated and which have remained unexplored.
