A feature of the Domain Name System (DNS) that verifies answers to domain name lookups is called Domain Name System Security Extensions
DNSSEC uses a different method than encryption public key cryptography to defend networks from man-in-the-middle attacks
Domain Name System (DNS) converts human-readable domain names into machine-readable IP addresses for online security in the digital age
DNSSEC guarantees authenticity and data integrity, reducing the risk of MitM attacks, in which attackers intercept and alter DNS responses to trick users
DNSSEC is being implemented more often, despite not being widely used. It is supported by a large number of prominent domain registries and registrars
Although DNSSEC setup and configuration may call for some technical know-how, the advantages greatly exceed the drawbacks
Domain Name System Security Extensions deployment was left optional so that organizations could make the switch whenever they felt ready
