What is DNSSEC?
DNSSEC, or Domain Name System Security Extensions, is a security protocol suite that adds cryptographic signatures to DNS data. It verifies that DNS responses originate from the authoritative DNS server and haven't been tampered with during transit. This helps prevent DNS spoofing and cache poisoning attacks by ensuring the authenticity and integrity of DNS information.
