ABSTRACT
This chapter proposes a novel Internet of Things (IoT) security framework which discusses security issues and countermeasure techniques at various layers in IoT environment. It also proposes attack taxonomy and discusses various attacks concerning each layer. The chapter provides a real-time case study based on Denial of Service attack for home automation application. It highlights the state-of-the-art research challenges to provide future directions to researchers in this area. Some IoT devices are used in our day-to-day life such as hospitals, homes, electronics appliances, and healthcare, etc. However developing a new application of IoT contains several challenges, object identification, highly complex structure and distribution, lack of common platform, distinguishing protocols, and involvement of third party services. There are several security attacks that target IoT layers. In general, these attacks can be classified into five categories: physical attack, side-channel attack, cryptanalysis attacks, network attacks, and software attacks.
