DDoS in IoT: A Roadmap Towards Security & Countermeasures
Ammara Roohi, Muhammad Adeel, Munam Ali Shah · 2019
In this era of digitization, more and more technologies are spurring up but are failing to make a successful impact due to the security and privacy issues. Internet of Things (IoT) has made its mark recently and being end-consumer oriented, makes it more prone towards being exploited. There are many types of security attacks in the IoT which can compromise the end user data and services. The most common and devastating security attack in the IoT is a Denial of Service (DoS)/Distributed Denial of Service (DDoS) attack. In this paper, the contributions are: we provide a structured & comprehensive overview of the existing research on DDoS Attacks, its security & countermeasures in the context of IoT. We survey latest vulnerabilities and their security solutions over the period 2014-2019. With elaborate discussion on IoT architecture and underlying security threats impacting each layer in the IoT, we have grouped existing approaches and derived taxonomy. With this concise overview, the paper seeks to provide an understanding of the pertaining models adopted by different researchers.
