DNSSEC is a security measure that strengthens authentication in DNS. It helps protect the internet from hackers by making sure that the websites you visit are actually the ones you intended to visit. In order to understand what DNSSEC is, you need first to understand what DNS is, also known as Domain name system or Domain name server. DNSSEC is an extension on top of DNS which is designed to help with this. In a nutshell, DNSSEC signs all responses at every layer of the DNS lookup process. This includes communication between the root nameservers, TLD nameservers, authoritative nameservers as well as recursive resolvers.

The Domain Name System Security Extensions (DNSSEC) is a feature of the Domain Name System (DNS) that authenticates responses to domain name lookups. It does not provide privacy protections for those lookups, but prevents attackers from manipulating or poisoning the responses to DNS requests.

DNSSEC isn't required for every website or organization, but it's strongly recommended for sites that handle sensitive information or have a high risk of cyberattacks. DNSSEC helps ensure the integrity and authenticity of DNS, which is particularly important for organizations that handle financial transactions, medical records or other sensitive data.DNSSEC uses both standard DNS record types and digital signatures that are maintained in name servers. Data is verified by DNSSEC using a system of public keys and digital signatures. It merely augments the DNS with additional records. For DNSSEC validation, public key cryptography is used as a foundation. DNSSEC protects internet users and applications from forged domain name system (DNS) data by using public key cryptography to digitally sign authoritative zone data when it enters the DNS and then validate it at its destination. Learn more about public key cryptography. A digital signature helps assure users that the data originated from the ...
