CRY-05.04B

If any changes of these procedures and technical safeguards may affect the confidentiality of the cloud service customer data, the cloud service provider communicates these changes to the cloud service customers.

Supplementary information

The requirement of 'accessible only by the cloud service customer' means that encryption keys remain solely within the knowledge and control of the owner. This can be addressed by implementing a secure key management system. If a key management system is used, the keys need to be protected from usage not explicitly authorised by the owner of the key and remain inaccessible in plaintext.

This criterion does not apply to data that cannot be encrypted for the provision of the cloud service for functional reasons.
