Microsegmentation in Hybrid Data Centers: Stopping East-West Attack Traffic
Implementing software-defined networking and distributed firewall policies to isolate workloads across on-prem and cloud environments.
The Failure of North-South Perimeter Firewalls
Traditional enterprise perimeter firewalls inspect incoming and outgoing traffic (North-South). However, once an attacker bypasses the perimeter, traffic between internal servers (East-West) typically flows without any firewall inspection.
Implementing Software-Defined Microsegmentation
Software-defined microsegmentation (via VMware NSX, Cisco ACI, or cloud security groups) enforces stateful firewall inspection at the virtual network adapter level of every individual workload.
Designing Zero-Trust Workload Groups
Group workloads by business application tier and strictly prohibit lateral database-to-database or web-to-web communications, halting ransomware worm propagation instantly.
