The Domain Name System (DNS) is one of the core Internet services. It provides the vital function of translating human readable domain names into IP addresses and supports most Internet applications, commercial content distribution platforms, and many security services. Distributed Denial of Service (DDoS) attacks against the DNS can therefore have devastating effects.
Rigorous and systematic measurement and analysis are essential for quantifying the risks of DDoS attacks against DNS and the benefits of proposed solutions. In this project we seek to develop and extend tools that generate actionable intelligence to support protecting the DNS against DDoS attacks, including, wherever possible, preventing such attacks before they occur. To attain this objective, we will:
- perform a systematic analysis of vulnerabilities in the current DNS using comprehensive active DNS measurement data from the OpenINTEL project that covers 60% of the global DNS name space;
- analyze the DNS DDoS ecosystem, identifying attack sources, targets, and characteristics;
- synthesize the resulting insights into a coherent unified view that considers both ongoing attacks and current vulnerabilities.
The results of this project will provide recommendations for protective measures that would help to minimize the risk and impact of DDoS attacks as well as yield clear guidance for improving DNS resilience.
