VMware Cloud Foundation Network Security: NSX Segmentation and Operations
Apply NSX segmentation in VMware Cloud Foundation with policy design, operational visibility and safe change controls.
Core design principles
Start with an application communication map. Define only the flows a service requires, then use policy groups and tags to avoid rules tied permanently to individual IP addresses.
Design for visibility before enforcement. Use monitoring and staged policy rollout to identify unexpected dependencies before a deny rule affects production.
Protect management paths separately. East-west application policy does not replace secure administration, certificate hygiene, MFA and controlled access to platform services.
Operational checklist
Define ownership, document the architecture and dependencies, protect privileged access, monitor the service, test recovery or rollback, and review the design after every material change.
