1. Using the Web, search for “software firewalls.” Examine the various alternatives available
and compare their functionality, cost, features, and type of protection. Create a weighted ranking
according to your own evaluation of the features and specifications of each software package. Software

2. Using Figure 6-15, create rule(s) necessary for both the internal and external firewalls to allow
a remote user to access an internal machine from the Internet using the software Timbuktu. This
requires researching the ports used by this software packet.
The ports to allow a remote user to access an internal machine from the Internet using the
software Timbuktu is ports 1417/tcp – 1420/tcp.
3. Using Figure 6-15, suppose management wants to create a “server farm” that is configured to
allow proxy firewall in the DMZ to access an internal Web server (rather than a Web server in
the DMZ). Do you foresee any technical difficulties in deploying this architecture? What
advantages and disadvantages are there to this implementation?
As far as technical difficulties, it would be exposed to higher level risks from a less trusted
network. The advantage would be gaining extended access to an internal Web server. But the
disadvantage would be you would have to accept the risk of getting exposed to un-trusted users.
