IAM-07.03AS

Access to cloud service customer data and cloud service derived data by internal or external personnel of the cloud service provider requires the prior consent of an authorised department of the cloud service customer, provided that the cloud service customer's data is accessible in unencrypted form or contractual agreements do not explicitly exclude such consent. Additionally, if encrypted data and its decryption key are stored separately within the same cloud environment, prior consent is required not only for accessing the decryption key but also for accessing the encrypted data itself (potentially together with the key).

Access to cloud service customer data also entails disclosure of data as part of investigation requests according to INQ-03. These are to be communicated to cloud service customers as far as it is legally not forbidden.

The criterion aims at minimising the cloud service provider's capability to access cloud service customer data. Minimisation of the cloud service provider's possibility to access cloud service customer data is often a question related to the radius of the collusion circle. For example, if the four-eyes principle for access is applied and the access is being logged, then three people make up the collusion circle. In order to build trust into such access statements, the cloud service provider should describe in the system description the measures taken to enlargen the collusion circle.
