The Internet of Things (IoT) comprises the interconnection of a wide range of different devices, from Smart Bluetooth speakers to humidity sensors. The great variety of devices enables applications in several contexts, including Smart Cities and Smart Industry. IoT devices collect and process a large amount of data on machines and the environment and even monitor people's activities. Due to their characteristics and architecture, IoT devices and networks are potential targets for cyberattacks. Indeed, cyberattacks can lead to malfunctions of the IoT environment and access and misuse of private data. This chapter addresses security concerns in the IoT ecosystem. It identifies common threats for each of IoT layers and presents advantages, challenges, and limitations of promising countermeasures based on new technologies and strategies, like Blockchain and Machine Learning. It also contains a more in-depth discussion on Intrusion Detection Systems (IDS) for IoT, a promising solution for cybersecurity in IoT ecosystems.
