Episode notes
Microsegmentation Defined
- Microsegmentation involves dividing a network into very small, isolated segments even within the same network zone.
- It enforces least privileged access beyond traditional network segmentation like VLANs.
VLANs Don't Scale Well
- VLANs do not scale well for fine-grained segmentation across large organizations.
- Microsegmentation aims for greater granularity than VLANs but requires new approaches to scale efficiently.
Microsegmentation Use Cases
- Microsegmentation use cases include workload segmentation, user-to-resource access, and IoT or unagentable device control.
- It enables fine-grained, least privilege access control replacing broad implicit trust zones like typical VPNs.
