Abstract(in English) | A distributed denial-of-service (DDoS) attack is a major social problem. As one of the actual attacks, Dyn DNS, the Domain Name System (DNS) provider used by many well-known sites, was subjected to a DNS DDoS attack in 2016, causing these well-known sites to become inaccessible. This paper tackles the DNS water torture attack used in this cyberattack on Dyn DNS as a DDoS attack model. To perform a DNS water torture attack, attackers create a large number of unique fully qualified domain names (FQDNs) with a random label attached to the targeted domain, and then send the attack DNS queries to the targeted authoritative DNS server via DNS cache servers, which brings down the authoritative DNS server. This paper proposes an effective detection and prevention method against stealthy DNS water torture attack that is difficult for attack source side to detect, which quickly detects the occurrence of the attack on the targeted side and performs effective prevention on the attack source side. |
