Concept Breakdown: What is a DMZ in network security?

A DMZ (Demilitarized Zone) is a subnetwork that exposes external-facing services to the internet while isolating the internal LAN.

In network security, the perimeter refers to the boundary that separates an internal network (LAN) from the external network (internet).

In the context of network security, public services refer to services that are exposed to the internet for use by external entities.
