Collaborative intrusion detection in the era of IoT: Recent advances and challenges

Internet of Things (IoT) is currently transferring the conventional networks by allowing various devices to connect with each other, and the continued growth of IoT networks can benefit many organizations such as enterprises, consumers, and governments. Due to the distributed architecture of IoT networks, collaborative intrusion detection networks (CIDNs) are becoming a promising solution, which can deploy various detectors and allow them to exchange required information in order to enhance the detection performance. This chapter aims to survey the recent development of CINDs/networks in different disciplines. It then highlights some advanced insider attacks that may bypass the existing trust mechanisms and presents some promising solutions. The chapter also discusses existing open challenges and future directions in this area. IoT security threats have become more severe than ever; there is a demanding need for a strong, robust, and accurate CIDN/collaborative intrusion detection system/distributed intrusion detection system in practice.
