Firewall Change Control Process
Imagine you finally have your new firewall up and running. After much consultation with users, its governing rules are in place and functioning properly. However, you receive two requests for changes in the firewall during the first week:
1. The head of marketing would like the local newspaper to have daily network access to download employment ads from the marketing file server.
2. The firewall has broken the head of research and development's connection to a favorite website. He wants his access back and has asked for your help.
Discuss how you would respond to these requests. What kinds of procedures are needed to ensure that proper requests are implemented and inappropriate requests are denied?
Assignment –
Selecting, Positioning, and Configuring a Firewall
Overview
As we have discussed, firewalls can be software or hardware based, and each has its pros and cons. In this assignment you identify an appropriate position for a hardware-based firewall on the Anchor Hospital network and explain why it was chosen to replace Windows Firewall.
Preparation
· Make sure you have completed the unit lab and saved your screenshots before beginning work on the assignment.
· Review the Anchor Hospital Scenario (linked in Resources) as needed.
· Refer to the Create a Network Diagram tutorial (linked in Resources) as needed.
Instructions
Populate the Lab Template (linked in Resources) with your screenshots and describe briefly but specifically what you learned from or observed in the lab.
Currently the Anchor Hospital network uses Windows Firewall. A decision has been made to switch to a hardware firewall solution. Complete the following:
· Position the new hardware for maximum effectiveness in the Anchor network to reflect the positioning. Explain your reasoning for its placement and update your network diagram from the Unit 1 assignment.
. Note: Make sure you have responded to any instructor feedback on your diagram so you are working with an accurate and appropriate diagram.
· Suggest three plausible reasons why Anchor Hospital might switch to a hardware-based solution from Windows Firewall.
. Explain how the change may enhance network security.
Additional Requirements
· Include your updated diagram and lab screenshots in the template as specified.
· Label your document clearly.
· Use an appropriate typeface and size, such as Times New Roman, 12 points, for body copy. Use double-spacing.
· Apply current APA style and formatting as appropriate.
