The Domain Name System Security Extensions (DNSSEC) is a suite of extension specifications by the Internet Engineering Task Force (IETF) for securing data exchanged in the Domain Name System in Internet Protocol networks.
OpenDNSSEC was created as an open-source turn-key solution for DNSSEC. It secures DNS zone data just before it is published in an authoritative name server . OpenDNSSEC takes in unsigned zones, adds digital signatures and other records for DNSSEC and passes it on to the authoritative name servers for that zone.
DNSSEC is becoming more widespread as the deployment of a DNSSEC root key has been done by ICANN. Deployment to individual sites is growing as top level domains start to deploy DNSSEC too. The presence of DNSSEC features is a notable characteristic of a DNS server. TSIG Servers with this feature typically provide DNSSEC services.

DANE needs the DNS records to be signed with DNSSEC for its security model to work. Additionally DANE allows a domain owner to specify which CA is allowed to issue certificates for a particular resource, which solves the problem of any CA being able to issue certificates for any domain.
DNS responses traditionally do not have a cryptographic signature, leading to many attack possibilities; the Domain Name System Security Extensions (DNSSEC) modify DNS to add support for cryptographically signed responses. [51] DNSCurve has been proposed as an alternative to DNSSEC.
