Supplementary information on all sub-criteria
This criterion is typically not applicable to the SaaS service model.
Suitable SDN methods for increasing confidentiality are, for example, L2 overlay networking (tagging) or tunnelling/encapsulation.
Basic criterion
If the cloud service offers functions for software-defined networking (SDN), the confidentiality of cloud service customer data is ensured by suitable SDN procedures.
The cloud service provider validates the functionality of the SDN functions before providing new SDN features to cloud service customers or modifying existing SDN features. Identified defects are assessed and corrected in a risk-oriented manner.
Complementary customer criteria
What cloud service customers implement on their side.
Cloud service customers ensure with suitable controls that they validate the functionality of SDN features for their individual use cases before using newly introduced capabilities or modifed existing ones.
