DNS DDOS — a distributed denial-of-service attack that overwhelms DNS infrastructure with traffic or expensive queries to impair name resolution.
The attack exploits trust in DNS, caching behavior, or the size difference between queries and responses. Mitigation requires a combination of DNSSEC validation, restricted recursion, source-address filtering, rate controls, and resilient infrastructure.
DNS DDOS — a distributed denial-of-service attack that overwhelms DNS infrastructure with traffic or expensive queries to impair name resolution.
An attacker attempts to forge a DNS answer, place false data in a cache, or use DNS servers to amplify traffic toward a victim. The exact technique depends on the attack type.
Disable open recursion, keep DNS software updated, use DNSSEC validation where applicable, limit abusive queries and responses, deploy source-address filtering, and monitor anomalous traffic.
