Techopedia Explains Microsegmentation (Networks and Cybersecurity)

Microsegmentation for a network can be done in various ways. One type of micro-segmentation is user micro-segmentation, where an individual user may only have access to a small part of a network instead of the whole thing. Other types of micro-segmentation put up gates or partitions between areas of network data traffic, for example, to split up connections between dedicated network nodes.
