Explanation

A DMZ (Demilitarized Zone) is a network segment that sits between the untrusted Internet and the trusted internal corporate network. Public-facing servers (web servers, mail servers, DNS) are placed in the DMZ so that if they are compromised, attackers cannot directly reach the internal network. Firewalls on both sides control traffic in and out of the DMZ. NAC (Network Access Control) enforces endpoint compliance policies. IPSec is a VPN/encryption protocol. NAT (Network Address Translation) maps private IP addresses to public ones but does not create network isolation. Only a DMZ architecturally isolates servers from both the Internet and the corporate network simultaneously.
