What is DNSSEC?

DNSSEC is a feature of the Domain Name System (DNS) that authenticates responses to domain name lookups. It prevents attackers from manipulating or poisoning the responses to DNS requests. DNS technology was not designed with security in mind. One example of an attack on DNS infrastructure is DNS spoofing. In which case an attacker hijacks a DNS resolver’s cache, causing users who visit a website to receive an incorrect IP address and view the attacker’s malicious site instead of the one they intended.

Wie DNSSEC funktioniert?

When you activate DNSSEC, we will generate a public and private key for your zone. The public key is provided to you in the form of DS or DNSKEY records. The records should be configured at the domain provider, where the domain name is registered. During the deployment of your zone in our network, we will use the private key to sign all your records. These signatures will be received and checked by the end-user resolver if they match with the public keys and the resolver will be able to authenticate that the records are not manipulated during the network transfer.
