Trend Analysis and Countermeasure Research of DDoS Attack Under 5G Network

DDoS has been terrorizing network operators since its birth in the late 20th century, and people are constantly researching new methods and techniques to mitigate or solve DDoS attacks. However, with the network technology update iteration, DDoS attacks also emerge in endlessly. When we exclaims the high speed experience brought by 5G, we should not forget that the network is a double-edged sword, and the security problem of 5G network is also not to be underestimated. As traditional DDoS defenses continue to fail, researchers who have grown more aggressive in recent years have seen some promising, low-cost technologies emerge. This paper first analyzes the trend of DDoS attacks in the past two years, then analyzes some DDoS defense mitigation schemes based on SDN, NFV and MTD, and points out some challenges faced by using new technologies to defend DDoS attacks.
