1. Using the Web, search for “ software firewalls.” Examine the various alternatives avail-able 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.

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 soft-ware Timbuktu. This requires researching the ports used by this software packet.

3. Using Figure 6- 15, suppose management wants to create a “ server farm” that is configured to allow a 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?
