Security of the network connectivity between the different zones of the Service, as illustrated in Figure 1, is a shared responsibility between Dell and customer.
Dell owns, and is responsible for, the security of the communication channel from the onsite management stack to the vault. Traffic to and from the Service is encrypted using TLS v1.2/v1.3 and separated through a dedicated firewall.
The customer is responsible for configuring network firewall rules for the traffic between the CMSP and the Service. Dell is responsible for securing and separating the remote management using designated Dell-managed network security.
Dell provides an additional network security layer to secure the communication between CMSP and the Service. The measures to secure this network are combined technologies that include VRF defined at top of rack (ToR), VLANs, and encryption communication through a designated firewall.
