Which of the following would be the MOST secure firewall system?

A.
Screened-host firewall

B.
Screened-subnet firewall

C.
Dual-homed firewall

D.
Stateful-inspection firewall

Explanation:

A screened-subnet firewall, also used as a demilitarized zone (DMZ), utilizes two packet filtering
routers and a bastion host. This provides the most secure firewall system, since it supports both
network- and application-level security while defining a separate DMZ network. A screened-host
firewall utilizes a packet filtering router and a bastion host. This approach implements basic
network layer security (packet filtering) and application server security (proxy services). A dualhomed firewall system is a more restrictive form of a screened-host firewall system, configuring

one interface for information servers and another for private network host computers. A statefulinspection firewall working at the transport layer keeps track of thedestination IP address of each
packet that leaves the organization’s internal network and allows a reply from the recorded IP
addresses.
