DNSSEC is specifically designed to prevent DNS spoofing, also known as cache poisoning, where an attacker injects malicious data into a DNS resolver’s cache, redirecting users to fraudulent websites. DNSSEC works by using digital signatures and public-key cryptography to verify the authenticity of DNS responses. This ensures that users always receive accurate and untampered domain-to-IP mappings. For instance, if a user attempts to access "example.com," DNSSEC validates the response from the authoritative DNS server, blocking any malicious attempts to redirect the user to a phishing site.
