The DNSSEC acronym stands for Domain Name System Security Extensions. It is a set of DNS protocol extensions that were introduced by IETF with the goal of signing DNS data to secure the domain name resolving process.
DNSSEC helps make the Internet safer. Because we are committed to providing the best in security to our clients, Plesk Onyx comes with the DNSSEC extension to help you protect the DNS data of hosted domains. The extension gives users the ability to do the following:
- Configure the settings used for key generation and rollover
- Sign and unsign domain zones according to the DNSSEC specifications
- Receive notifications related to DNSSEC records and keys
- View and copy DS resource records and DNSKEY resource record sets
DNSSEC is provided for free in Plesk Web Pro and Web Host editions. In Web Admin edition, it is paid.
