The Domain Name System Security Extensions (DNSSEC) is a suite of Internet Engineering Task Force (IETF) specifications for securing certain kinds of information provided by the Domain Name System (DNS) as used on Internet Protocol (IP) networks.How does DNSSEC work?
How DNSSEC Works. The domain name system (DNS) is the phone book of the Internet: it tells computers where to send and retrieve information. Unfortunately, it also accepts any address given to it, no questions asked. Email servers use DNS to route their messages, which means they’re vulnerable to security issues in the DNS infrastructure.What is the difference between DNSSEC and DNS security?
The difference between DNSSEC and DNS security is that DNSSEC is part of DNS security, whereas DNS security is a larger, more general concept that covers a wide range of technologies and solutions. DNSSEC is a standardized solution to add authentication to DNS responses, providing authentication of the sender and the integrity of the message.
