Detailed explanation-1: -To build a Demilitarized Zone Network, you need a firewall with three network interfaces: one for untrusted networks (Internet), one for the DMZ, and one for the internal network.
Detailed explanation-2: -What is a DMZ network? In computer security, a DMZ network (sometimes referred to as a “demilitarized zone”) functions as a subnetwork containing an organization’s exposed, outward-facing services. It acts as the exposed point to an untrusted network, commonly the internet.
Detailed explanation-3: -A DMZ, short for demilitarized zone, is a network (physical or logical) used to connect hosts that provide an interface to an untrusted external network – usually the internet – while keeping the internal, private network – usually the corporate network – separated and isolated form the external network.
