Network Segmentation
Isolate sensitive zones.
What Is Segmentation
Network segmentation divides a network into smaller, isolated zones.
Each zone is separated by controls so traffic between them can be inspected and restricted.
The Flat Network Problem
A flat network puts every device in one big zone.
If an attacker breaches one machine, they can freely reach all the others. Segmentation breaks that path.
