Network-Layer DDoS Attack Trends for Q1 2020

What this post added

This post analyzes network-layer DDoS attack trends for Q1 2020, noting a rise in smaller, shorter attacks (under 10 Gbps, under 1 million pps, 30-60 minutes duration) attributed to DDoS-as-a-service and the ROI for attackers. It also highlights the persistence of larger attacks (up to 550 Gbps) and a decrease in attacker persistence compared to Q4 2019. The analysis details top attack vectors (SYN, ACK, CLDAP) and observes an increase in attacks during the COVID-19 crisis, with a surge in large-sized attacks in late March. Cloudflare's mitigation strategies are discussed in relation to these trends, emphasizing rapid Time To Mitigate SLAs, distributed architecture, and massive network capacity.
