An SDN-based Approach For Defending Against Reflective DDoS Attacks
Distributed Reflective Denial of Service (DRDoS) attacks are an immanent
threat to Internet services. The potential scale of such attacks became
apparent in March 2018 when a memcached-based attack peaked at 1.7 Tbps. Novel
services built upon UDP increase the need for automated mitigation mechanisms
that react to attacks without prior knowledge of the actual application
protocols used. With the flexibility that software-defined networks offer, we
developed a new approach for defending against DRDoS attacks; it not only
protects against arbitrary DRDoS attacks but is also transparent for the attack
target and can be used without assistance of the target host operator. The
approach provides a robust mitigation system which is protocol-agnostic and
effective in the defense against DRDoS attacks
