DMZ

“Demilitarized Zone” or “DMZ” is a network or sub-network that sits between a trusted internal network, such as a corporate private Local Area Network (LAN), and an untrusted external network, such as the public Internet. A DMZ helps prevent outside users from gaining direct access to internal Information Resources. Inbound packets from the untrusted external network must terminate within the DMZ and must not be allowed to flow directly through to the trusted internal network. All inbound packets which flow to the trusted internal network must only originate within the DMZ
