CRY-16.02B

Procedures for the recovery of lost or corrupted keys are in place.

The cloud service provider should consider the following options for safeguarding key material:

1. Backup of keys: Encrypted backups of keys are stored securely outside the HSM. The backup process should ensure that the keys are encrypted during storage and transit to prevent unauthorised access. Regular testing of backup and recovery procedures should be carried out to verify the effectiveness and integrity of the backups. Backups outside a HSM should only be considered after dilligent risk assessment.
2. Redundant HSMs: Implementing multiple HSMs in geographically dispersed locations to create redundancy to ensure that keys remain available and secure even if one HSM fails. The HSMs should be synchronised to ensure consistency of key material across all devices. Regular health checks and failover tests are necessary to ensure that redundancy mechanisms function correctly. The particular manner this redundancy is built may depend on the details of the contractual agreements between provider and customer. E.g. when the customer choose a particular location, zone or region, this choice also applies to the redundancy mentioned in this criterion.
