Domain Name System Security Extensions (DNSSEC)

Few technologies are more critical to the Internet than the Domain Name System (DNS), which translates domain names into IP addresses. DNS Security Extensions — DNSSEC — helps to ensure that you are communicating with the correct website or service.

DNS Security (DNSSEC) is designed to authenticate DNS response data. It verifies responses to ensure a DNS server’s response is what the zone administrator intended. It does not address all threats (nothing does), but it provides a building block for providing additional data security, and not just within the DNS but also within the applications and services that are built on it.

DNSSEC acts like tamper-proof packaging for domain name data, giving users more confidence in their online activities. DNSSEC provides a level of additional security where your web browser can check to make sure the DNS information is correct and was not modified. DNSSEC also provides us with a platform for future innovations to enhance user confidence in Internet-based services.
