Why Is DNS Security Important?

DNS Spoofing or Cache Poisoning

Attackers may attempt to insert false DNS records into the cache of a DNS resolver, redirecting users to malicious websites.

DNS Amplification Attacks

This involves exploiting misconfigured DNS servers to amplify a small attack into a much larger one, overwhelming the target.

DNS DDoS Attacks

Distributed Denial of Service attacks targeting DNS servers can disrupt or overload the DNS infrastructure, making websites inaccessible.
