ABSTRACT
Internet of Things (IoT) is the network where physical objects are connected. People began to be concerned about the security of IoT when more and more devices in IoT were found vulnerable to hacking and it was reported on headline news recently. Cybersecurity in IoT faces many challenges. IoT is highly heterogeneous. The devices in IoT are heterogeneous. The data in IoT are heterogeneous. Big data analytic (BDA) methods for cybersecurity adopt big data analytic technologies to solve big data cybersecurity problems. IoT relates to people's daily lives closely. The applications of IoT cover almost all the aspects of people's lives. The technology of IoT is used to build smart homes where all the home appliances, such as TV, refrigerator, microwave oven, and so on, are smart. IoT is a giant complicated network of many subnetworks involving a huge amount of devices, different protocols, different data structures, different message formats, and different system requirements.
