Demilitarized Zone

Definitions

1. A network segment placed between untrusted external networks and trusted internal systems to host public-facing services under tighter isolation. The idea is to limit how far an attacker can move if an internet-exposed server is compromised.

   In plain English: An isolated network area for internet-facing systems.

   Example: "The mail relay sat in a demilitarized zone instead of on the internal network."
