DDoS Attack, a Threat to IoT Devices in the High-Speed Networks—An Overview

High-speed communication technology with the implementation of 5G and Wi-Fi-6 is now getting popular, and the usage of these technologies is growing fast. The Government of India has announced the fast paced implementation of 5G and then to look forward to 6G Technology. The vulnerability and potential attack possibilities grow as data transfer rises, and as more and more devices gets connected to the next generation network. Ability to employ this technology for mission-critical applications has been made possible by the Wi-Fi-6 and 5G network, making it crucial to have security solutions in place. In this paper, we have tried to focus on the most widely used attack, i.e., IoT-DDoS attack on the next generation high-speed network, with the technologies like SDN, these attack can devastate the network itself. Further, we discuss the possible threat that may use the smallest devices, i.e., IoT devices for the launch of DDoS attacks. Further, the paper discusses the possible mitigation for the security of these devices, networks, and resources.
