Super-Router: A Collaborative Filtering Technique Against DDoS Attacks

DDoS attack is one of the well known cyber attacks of Internet era, which affects on the availability of the network. In 1999, though Computer Incident Advisory Capability (CIAC) reports the first ever DDoS attack, but first major DDoS attack was recorded in year 2000 on some of the big websites e.g., Yahoo, Amazon, CNN, eBay etc. due to which their services went offline for few hours and huge amount of revenue losses were recorded. Since then DDoS attacks become favourite attacks of antagonists. There are so many different defense techniques available to detect and filter malicious traffic, but none of these methods could adequately filter out the malicious traffic. In this context, this paper proposed a new filtering scheme, Super-router, which uses collaborative filtering technique to filter malicious traffic. More specifically, Super-router uses unicast method of communication between filters which reduces the communication overheads and response time of individual filters. This makes Super-router an effective defense against DDoS attacks for high speed networks.
