COS-06.01B

Cloud service customer data traffic in jointly used network environments is separated on network level according to a documented framework to ensure the confidentiality and integrity of the data transmitted.

If the cloud service provider does not use shared network environments for cloud service customers and instead uses a physical separation, the basic criterion is not applicable.

If the suitability and effectiveness of the logical segmentation cannot be assessed with sufficient certainty (e.g. due to a complex implementation), evidence can also be provided based on audit results of expert third parties (e.g. security audits to validate the framework). The separation of stored and processed data is subject of the criteria OPS-30 and OPS-31. After successful authentication via an insecure communication channel (HTTP), a secure communication channel (HTTPS) is to be used.

With IaaS/PaaS, secure separation is ensured by physically separated networks or encryption of the networks that corresponds to the state of the art. For the definition of state of the art encryption, the BSI Technical Guideline TR-02102 should be considered (cf. CRY-01).
