B. Screened-subnet firewall

Out of all types of firewall implementation structures, Screened Subnet Firewall provides greatest security environment (as it implements 2 packet filtering router and 1 bastion host). It acts as proxy and direct connection between internal network and external network is not allowed. A screened-subnet firewall is also used as a demilitarized zone (DMZ). Difference between screened-subnet firewall and screened host firewall is that, screened-subnet firewall uses two packet filtering router whereas screened-host firewall uses only one packet-filtering firewall.
