Chapter 6, Problem 14RQ
Program Plan Intro
Firewall architecture:
Entire firewall devices are configured in various network architectures. They might be mutually exclusive, but sometimes may not be. It works best for an organization that depends on following factors:
- Main purposes of the network
- Company’s capacity to establish the architectures
- Cost of the utilities.
The common architectural implements of firewall are:
- Single bastion hosts
- Screened host architecture
- Screened subnet architecture

How do screened host architectures for firewalls differ from screened subnet firewall architectures? Which of these offers more security for the information assets that remain on the trusted network? Why?
What are the key responsibilities of a network firewall in the context of the OSI model? In which layer(s) does it operate?
At what two layers of the Open Systems Interconnection (OSI) model does a packet-filtering firewall operate?
