In the process of DNS resolution, the client initiates a query request, and the DNS server may need to make additional queries to complete the resolution process and give a response, which will consume certain computing and network resources. If an attacker uses a large number of controlled hosts to continuously send resolution requests for different domain names, the cache of the DNS server will be continuously refreshed, and the failure of a large number of resolution requests to hit the cache will cause the DNS server to consume additional resources for iterative queries, which will greatly increase the resource consumption of the DNS server.
Both these attacks and SYN flooding target the victim's TCP application and can interrupt the victim's service at much less cost than brute force flooding packet methods. However, SYN flooding is very different from other TCP spoofing attacks. SYN flooding attacks the services of the new connection without affecting the established connection, while other spoofing attacks break the established connection and cannot block the new connection from the beginning. SYN attacks can be stopped only by modifying the initial handshake program, while other spoofing attacks require checking every piece of data throughout the connection life cycle. What SYN flooding and other TCP spoofing attacks have in common is that they all depend on the attacker's ability to send IP packets that disguise the source address, while the same way to defend them is to deploy more address filtering or use IP Security Protocol (IPsec).
