Rajarajan Ganesarathinam, Muthukumaran Singaravelu, K Pooja · 2022
The promising nature of the Internet, its related technologies, and the applications has brought a significant impact on human beings’ day-to-day activities in the past three decades. As a part of its evolution, the current trend is the Internet of Technology (IoT), which brings automation to the next level via connecting the devices through the Internet, and its benefits are tremendous. Meanwhile, the threats and attacks are also evolving and become an unstoppable menace to IoT users and applications. In this chapter, we are presenting the various security loopholes and concerns in the existing layered architectures of IoT. Out of many attacks and threats over IoT, we have specifically chosen Distributed Denial of Service (DDoS) attacks because of its severity in the IoT environment and dealt extensively with the different categories of DDoS impact as well as a review of existing countermeasures against DDoS in IoT. Further, this chapter addresses critical challenges and future research directions concerning IoT security that gives insights to the new researchers in this domain.
