This project simulates a real enterprise -class secure network infrastructure for a cloud-technology company with 600+ employees, multiple floors, department segmentation, redundancy, VoIP services, wireless infrastructure, server rooms, and DMZ hosting. This project demonstrates: Enterprise LAN design Multi-layer switching Firewall zone ...

Demilitarized Zone (DMZ)
Explore real-world DMZ examples and different DMZ architectures (single vs. dual firewall ): Why is DMZ important in network security ? DMZs add a layer of network segmentation to defend internal private network . It creates a buffer zone between the public internet and organization's private networks .






I've seen some posts on Reddit asking about DMZ design so I formulated this design scenario in response to those questions. We will look at a DMZ for a small business with just 1 firewall , a medium sized business with a zone-based firewall , and then a larger network that utilizes hardware segmentation.
