FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The DMZ subnet is deployed between two firewalls. All inbound network packets are then screened using a firewall or other security appliance before they arrive at the servers hosted in the DMZ. A network DMZ sits between two firewalls, creating a semisafe buffer zone between the internet and the enterprise LAN.

Detailed explanation-2: -Dual-homed host firewalls One of the NIC is connected to the external network, and the other one is connected to the internal network thus providing an additional layer of protection.

Detailed explanation-3: -A screened subnet uses two firewalls. The external firewall is connected to the internet and allows access to public resources. The internal firewall connects the screened subnet to the private network.

Detailed explanation-4: -Since it adds an additional layer of security to the network, a screened subnet is suitable for many high-traffic sites. The screened subnet’s main purpose is to isolate a demilitarized zone (DMZ) and its publicly accessible resources from an internal network to minimize possible attacks on the subnetwork.
