Alekos is designing layered network security for his organization. He wants to implement security controls in his data center at the level of individual services and workloads. He plans to use firewall rules and other controls as well as on-demand access to services as part of his security design. What design concept is he implementing?

Micro-segmentation is used to logically separate systems and services by defining boundaries between them. This is often part of a zero-trust architecture including the use of on-demand access to services. Converged protocols implement other protocols over another protocol like iSCSI or InfiniBand over Ethernet. Physical segmentation uses separate physical devices and infrastructure to provide segmentation. Edge networks place computation and storage closer to the end-user.
