The DNSSEC ‘Ceremony Guidebook’ includes procedures and processes to be followed with respect to Hardware Security Modules (HSM) and DNSSEC Key material including tokens. It contains the operational Key Signing Key (KSK) procedures such as deploying a KSK rollover (including IANA procedures), creating a backup of the KSK and securing the backup of the KSK (HSM-) partition on a third secured location. A summary of the included procedures and processes are provided below. Operational KSK procedures - Creating a new KSK (normal operational procedure); - Safe keeping of the access tokens; - Gaining access to the access tokens in a safe. KSK rollover - Performing a KSK rollover, including the procedure for changing the DS record in the root (IANA procedure). Backup of the KSK partition - Creating a backup of the KSK. Hardware Security Modules - Initial configuration of a HSM; - Restore of a HSM; - Restore of all HSM’s. Safes - Initial configuration of the safes; - User management of the safes; - Storing the backup tokens and KSK partition backup in remote facility safes; - Storing and collecting the spare key of the remote facility safes at the notary.
