IoT-based DDoS on Cyber Physical Systems: Research Challenges, Datasets and Future Prospects

The fusion of widespread IoT devices, highly adopted cloud services, and advanced network technologies has laid the foundation of Cyber-Physical Systems. However, the architecture is highly vulnerable due to weak security bound to IoT devices. The IoT devices have played a significant role in launching DDoS attacks, thereby making the state of affairs catastrophic. The attacks are novel and traditional systems are not efficient enough to address high volume and diverse attacks. The roadblock to researchers is the unavailability of an adequate number of datasets that apprehends the diversity of attacks. The paper describes the specifications of cyber-physical systems, description of IoT-DDoS attacks, and highlights the research challenges. The paper further collates and elucidates the IoT-DDoS datasets with a comparative analysis of the test environment, features offered, and statistical details of datasets. At the end of the paper, based on the dataset study, recommendations are proposed for dataset standardization and extracting most out of the datasets.
