Microsegmentation breaks a network or data center into various segments to enhance its efficiency or security. The idea behind segmentation became an established technique once virtual local area networks (VLANs) came into use. From the very beginning, security was a central focus for VLAN segmentation, because it divided network domains into smaller parts and then protected movement of data among the parts. Traditional VLANs quickly reach their limits, however, when confronted with more extreme levels of segmentation, especially with regard to the management of security and configuration settings, because managing these settings becomes increasingly complex as the number of segments grows. Moreover, configuration tends to be rather static, whereas security orients more toward the IP layer of communication control, rather than to the application level.
