Microsegmentation is a technology that allows for granular control of east-west traffic in a software-defined network. Microsegmentation divides the network into smaller segments or zones based on application or workload characteristics, and applies security policies to each segment. This reduces the attack surface and prevents unauthorized access or lateral movement within the network. Routing, MAC Access Control List, and Virtualization are not technologies that provide microsegmentation, but they are related concepts that can be used in conjunction with microsegmentation.
