A screened subnet is a separate network segment positioned between an untrusted network (such as the internet) and the trusted internal LAN. It is created with one firewall that has three interfaces or with two firewalls in series. Public-facing servers reside in this DMZ so that, even if they are compromised, attackers must still bypass an additional firewall to reach the internal network. The other choices describe unrelated security technologies or physical controls.
