Let's pretend you're employed by a company that uses a firewall to keep its internal network safe from the wider Internet. Is it advisable to set up individual firewalls on all office computers? If so, why do you suppose that is?
Is there a typical link between a network that cannot be trusted, a firewall, and a network that can be trusted, and how does this connection function?
Consider a case where some servers require more contact with the outside internet than most systems belonging to a company. How can a company use firewalls to provide appropriate levels of protection to all their computers (drawing a diagram may help, but is not required)?
