3 Segmentation Threat Defense Visibility Establish boundaries: network, compute, virtual Enforce policy by functions, devices, organizations, compliance Control and prevent unauthorized access to networks, resources, applications Stop internal and external attacks and interruption of services Patrol zone and edge boundaries Control information access and usage, prevent data loss and data modification Provide transparency to usage Apply business context to network activity Simplify operations and compliance reporting
