Work-in-Progress: Analyzing Worst-Case DDoS Traffic Scrub Effect and Recovery Delay via Attack Vector Combination

Distributed Denial of Service (DDoS) continues to be a prevalent attack on Internet today, and DDoS mitigation has garnered significant attention from the academic and industrial communities. However, strong attackers could combine attack vectors and launch DDoS to allow as many attack packets as possible to pass through the filter. In this paper, we reveal this problem and model the attack vector combination as a combinatorial optimization problem solution, aiming to provide deep insights into the worst-case traffic scrub effect.
