- Download, install and run one of the following free firewall or application proxy products. Write a review
of the product as if you were writing for a blog or magazine. Explain what it does, how it works, any effects it has on your PC and whether or not you recommend it. Include screen shots of it working on your PC.
- Comodo (http://personalfirewall.comodo.com/)
- ZoneAlarm (http://www.zonealarm.com/security/en-us/zonealarm-pc-security-free-firewall.htm)
- TinyWall (http://tinywall.pados.hu/)
- In your own words, explain the differences and similarities between the three types of firewalls
(packetfiltering, stateful, and application proxy). Include where you could use each type. Write it as if you
were explaining the concepts to a novice.
- Explain where firewalls should be placed in a typical network. Include a explanation of a DMZ and how it
can protect the sensitive inside of a network. In what situations would you use multiple layers of firewalls.
(Hint: see chapter 3 of the NIST publication.) You should include one or more diagrams showing typical placement of firewalls.
