DNSSECprotected

DNSSECprotected denotes a domain whose DNS zone is signed with DNSSEC and whose data can be validated by resolvers. A DNSSECprotected zone provides cryptographic assurance that responses come from the authoritative source and have not been tampered with during transit.

DNSSEC adds signatures to DNS data. Each zone has a DNSKEY set; responses include RRSIG records; the parent zone holds a DS record that bridges the zone to the global chain of trust anchored at the root. Validators use this chain to verify authenticity.

A domain becomes DNSSECprotected when it is signed and a DS record is published at the parent zone. This requires ongoing key management, including signing key (ZSK) and key-signing key (KSK) rollover, proper visibility of signatures, and monitoring for expiration.

Operational considerations include choosing signing software, configuring automatic signing, publishing DS at the registrar, and regularly testing validation with trusted resolvers. Misconfigurations such as missing DS, unsigned delegations, or mismatched keys can render a domain unresolvable to some users.

DNSSEC protection does not provide confidentiality and does not enhance availability by itself. It relies on a functioning trust anchor and validator. Adoption varies by registry and resolver support, but when correctly deployed, DNSSECprotected domains enable stronger integrity guarantees for DNS.
