IoT Security Monitoring Tools and Models

Systems based on Internet of Things are more and more being used in many different critical domains. However, such devices introduce new vulnerabilities and trying to cope with them on devices that have limited resources remains a challenge. This chapter presents ongoing research on security modeling and monitoring for IoT networks and describes some of the most popular tools used. First, it describes different reference models and architectures designed for IoT and highlights the need for security features to provide the required trust and privacy. A presentation of the different security modelsSecurity models developed by different research teams allows identifying the most salient features and the challenges that still remain to be answered. This chapter also details different attack types that have high impact on IoT networks, some that are common in the Internet but others that are more specific to IoT. Finally, the chapter provides a description of a concrete example on how network monitoring and security analysis can be used to detect anomalous and malicious behavior. This chapter concludes by identifying some of the problems that still need to be addressed.
