Learn about DNS DDoS attacks, their impact on networks, and how to protect your organization against this type of cyberthreat.

A DNS flood is a type of distributed denial-of-service attack (DDoS) where an attacker floods a particular domain’s DNS servers in an attempt to disrupt DNS resolution for that domain.

A DNS reflection/amplification distributed denial-of-service (DDoS) attack is a common two-step DDoS attack in which the attacker manipulates open DNS servers. The cybercriminal first uses a spoofed IP address to send massive requests to DNS servers.

This DDoS attack leverages open DNS resolvers in order to overwhelm a server or network with an amplified amount of traffic, rendering the server and its surrounding infrastructure inaccessible.

Understand DNS attacks, how cybercriminals exploit vulnerabilities, and the best practices to secure your network from DNS hijacking and poisoning.
