Network Segmentation Testing: Verifying Isolation Between Zones cho Doanh nghiệp Việt Nam

Network segmentation divides a network into zones with controlled traffic flow between them — a fundamental defence-in-depth control. Segmentation testing verifies that the boundaries work: can a compromised system in one zone reach systems in another? Can an attacker in the DMZ reach internal databases? Can a guest network user access corporate resources? Testing maps actual traffic paths between zones and identifies segmentation gaps that would enable lateral movement during a real attack.
