What does DNSSEC stand for?

Explanation:
DNSSEC stands for Domain Name System Security Extensions. The idea is to attach cryptographic signatures to DNS data so a resolver can verify that a response is authentic and hasn’t been tampered with, creating a chain of trust from the root down to individual domains. It uses records like DNSKEY, DS, and RRSIG to sign zones and validate responses. Note that DNSSEC provides integrity and authenticity, not confidentiality, so it doesn’t encrypt the DNS traffic. Other options don’t match the actual acronym or purpose.
