What Does Domain Name Server Amplification Attack (DNS Amplification Attack) Mean?
A domain name server amplification attack (DNS amplification attack) is a sophisticated type of distributed denial-of-service attack (DDoS) that involves sending massive amounts of incoming data to a server. Through spikes in network traffic, the intent is to make a system unavailable to legitimate users.
Techopedia Explains Domain Name Server Amplification Attack (DNS Amplification Attack)
Experts characterize DNS amplification attacks as techniques that use specific kinds of DNS query protocols and available hardware setups to plague a system with unnecessary incoming queries. Earlier and more primitive DNS amplification attacks sent individual requests to central network resources. Due to a lack of handshake authentication, these nodes would distribute requests to other network system devices. These kinds of attacks have largely been prevented through modern network administration.
