DNS DDoS Protection

DNS DDoS Protection

Protect your DNS infrastructure from advanced DNS DDoS attacks

Protecting DNS is Critical for Your Business

When a DNS server falls victim to a DoS attack, users lose access to the websites, services and APIs associated with that server. If attacks target your organization, you could see far-reaching consequences that affect the availability of your applications, your customer relationships and your bottom line.

Radware’s DDoS Protection solutions use behavioral-based detection and automatic real-time signatures to identify and automatically block today’s most advanced DNS DDoS attacks. These DNS DDoS protections can be flexibly deployed—appliance, cloud-based and hybrid—to suit every customer’s need and deployment architecture.

Types of DNS DDoS Attacks

DNS Amplification Attack

Attackers exploit misconfigured DNS servers, making the DNS response much larger than the DNS request. The attacker sends a large number of small DNS queries with a spoofed source IP address to the targeted DNS server. The server then sends the amplified responses to the victim's IP address, overwhelming its network capacity

DNS Flood Attack

Attackers utilize a network of compromised computers called botnets to send a massive volume of DNS requests to the target DNS server, which floods the DNS server and causes it to become unresponsive

DNS Water Torture / DNS Random Sub-domain Attack

Attackers send a constant stream of small, legitimate-looking DNS queries to the victim's DNS server at a slow and steady rate. The continuous flow of queries gradually overwhelms the DNS server's resources and causes complete unresponsiveness over time

Phantom Domain Attack

Attackers set up one or more phantom domains and send requests to the victim's DNS server to resolve the phantom domains. The victim's DNS server gets overwhelmed when it tries to resolve the phantom domains through non-responsive servers

DNS NXDOMAIN Attack

Attackers flood DNS servers with requests for non-existent domains, resulting in DNS recursion and NXDOMAIN responses. This causes the server to process numerous requests for domain names that do not exist, consuming the resources and leading to denial of service
