What is DNSSEC?

DNSSEC, which stands for Domain Name System Security Extensions, is a set of protocols and extension mechanisms designed to add an extra layer of security to the Domain Name System (DNS). DNSSEC uses cryptographic signatures to ensure the authenticity and integrity of the DNS responses, preventing DNS spoofing and other cyberattacks. It works by digitally signing DNS records in a hierarchical manner from the root zone down to the individual domain names. By verifying these signatures, DNS clients can validate that the information received from DNS servers has not been tampered with. DNSSEC plays a critical role in enhancing the trust and security of DNS infrastructure and protecting users from malicious activities on the internet.
