Term Paper Project: Designing a Secure Network
Due Week 10 and worth 190 points

This term paper involves putting together the various concepts learned throughout this course. You are tasked with designing the most secure network possible, keeping in mind your goal of supporting three (3) IT services: email, file transfer (centralized), and VPN. Your first step is to design a single network capable of supporting there three (3) different services. Once you have fully designed your network, you will need to provide three (3) workflow diagrams explaining how your designed network handles the three (3) different transactions. The first is an internal user sending an email using his / her corporate email address to a user on the Yahoo domain with an arbitrary address of [email protected] The second workflow diagram should show a user initiating an FTP session from inside your network to the arbitrary site of ftp.netneering.com. The third workflow is an externally located employee initiating a VPN session to corporate in order to access files on the Windows desktop computer, DT-Corp534-HellenS, at work.

Write a ten to fifteen (10-15) page paper in which you complete the following three (3) Parts. Note: Please use the following page breakdown to complete your assignment:

• Overall network diagram: One (1) page
• Datapath diagrams: Three (3) pages (one for each diagram)
• Write-up: six to ten (6-10) pages

Part 1

• Using Microsoft Visio or its open source alternative, create a diagram showing the overall network you’ve designed from the user or endpoint device to the Internet cloud, and everything in between, in which you:
  • Follow the access, core, distribution layer model.
  • Include at a minimum:
    • Authentication server (i.e. Microsoft Active Directory)
    • Routers
    • Switches (and / or hubs)
    • Local users
    • Remote users
    • Workstations
    • Files share (i.e. CIFS)
    • Mail server
    • Web servers (both internal and external)
    • Firewalls
    • Internet cloud
    • Web proxy
    • Email proxy
    • FTP server (for internal-to-external transport)

• Explain each network device’s function and your specific configuration of each networking device.
• Design and label the bandwidth availability or capacity for each wired connection.

Part 2

• Using Microsoft Visio or its open source alternative, create a Datapath Diagram for the following scenario:
  • Local user sends email to a Yahoo recipient. Local (corporate) user having email address [email protected]sends an email to [email protected]
    • Document and label the diagram showing protocols and path of the data flow as data traverses through your network from source to destination. 
    • Include path lines with arrows showing directions and layer 1, 2, 3, 4, 5, 6, and 7 (OSI) protocols that are used for each flow. 
    • Show user authentication when necessary.
• Using Microsoft Visio or its open source alternative, create a Datapath Diagram for the following scenario:
  • Local user, Jonny Hill, transfers file using ftp through the Internet to another company’s site (ftp.netneering.com). He has to access the secure shell using his active directory credentials to authenticate to the ftp server (linux running Redhat) on the DMZ. He needs to transfer files from his desktop across the Internet to ftp.netneering.com.
    • Document and label the diagram showing protocols and path of the data flow as data traverses through your network from source to destination. 
    • Include path lines with arrows showing directions and layer 1, 2, 3, 4, 5, 6, and 7 (OSI) protocols that are used for each flow. 
    • Show user authentication when necessary.
• Using Microsoft Visio or its open source alternative, create a Datapath Diagram for the following scenario:
  • Remote user, Hellen Stover, connects via VPN from home through the Internet to her corporate desktop, DT-Corp534-HellenS. Hellen uses a browser to initiate her VPN connection. By browsing to https://VPNaccess.corp534.com, she arrives at a login page where she needs to authenticate using her Active Directory credentials before the VPN tunnel is built.
• Document and label the diagram showing protocols and path of the data flow as data traverses through your network from source to destination. 
• Include path lines with arrows showing directions and layer 1, 2, 3, 4, 5, 6, and 7 (OSI) protocols that are used for each flow. 
• Show user authentication when necessary.
• Explain how your overall design protects the organization from both inside and outside attacks. Give examples. 
• Explain how your layered design compensates for possible device failures or breaches in network security.
• Determine whether any possible bottlenecks exist in your design.
• Explain how to make the file transfer process more secure.

Part 3

• Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.

Your assignment must follow these formatting requirements:

• Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
• Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.
• Include charts or diagrams created in Visio or an equivalent such as Dia. The completed diagrams / charts must be imported into the Word document before the paper is submitted.

The specific course learning outcomes associated with this assignment are:

• Explain the essentials of Transmission Control Protocol / Internet Protocol (TCP / IP) behavior and applications used in IP networking.
• Identify network security tools and discuss techniques for network protection
• Describe the foundational concepts of VPNs.
• Design a secure network to address a business problem.
• Use technology and information resources to research issues in network security design.
• Write clearly and concisely about Advanced Network Security Design topics using proper writing mechanics and technical style conventions.

Problem 2:

Greener Grass Company (GGC) competes with its main rival, Better Lawns and Gardens (BLG), in the supply and installation of in-ground lawn watering systems in the wealthy western suburbs of a major east-coast city. Last year, GGC’s price for the typical lawn system was $1,900 compared with BLG’s price of $2,100. GGC installed 9,960 systems, or about 60% of total sales and BLG installed the rest. (No doubt many additional systems were installed by do-it-yourself homeowners because the parts are readily available at hardware stores.)

GGC has substantial excess capacity–it could easily install 25,000 systems annually, as it has all the necessary equipment and can easily hire and train installers. Accordingly, GGC is considering expansion into the eastern suburbs, where the homeowners are less wealthy. In past years, both GGC and BLG have installed several hundred systems in the eastern suburbs but generally their sales efforts are met with the response that the systems are too expensive. GGC has hired you to recommend a pricing strategy for both the western and eastern suburb markets for this coming season. You have estimated two distinct demand functions, as follows:

Qw =2100 – 6.25Pgw + 3Pbw + 2100Ag – 1500Ab + 0.2Yw

for the western market and

Qe = 36620 – 25Pge + 7Pbe + 1180Ag – 950Ab + 0.085Ye

for the eastern market, where Q refers to the number of units sold; P refers to price level; A refers to advertising budgets of the firms (in millions); Y refers to average disposable income levels of the potential customers; the subscripts w and e refer to the western and eastern markets, respectively; and the subscripts g and b refer to GGC and BLG, respectively. GGC expects to spend $1.5 million (use Ag = 1.5) on advertising this coming year and expects BLG to spend $1.2 million (use Ab = 1.2) on advertising. The average household disposable income is $60,000 in the western suburbs and $30,000 in the eastern suburbs. GGC does not expect BLG to change its price from last year because it has already distributed its glossy brochures (with the $2,100 price stated) in both suburbs, and its TV commercial has already been produced. GGC’s cost structure has been estimated as TVC = 750Q + 0.005Q2, where Q represents single lawn watering systems.

Show all of your calculations and processes. Describe your answer for each item below in complete sentences, whenever it is necessary.

Derive the demand curves for GGC’s product in each market.

Derive GGC’s marginal revenue (MR) and marginal cost (MC) curves in each market. Show graphically GGC’s demand, MR, and MC curves for each market.

Derive algebraically the quantities that should be produced and sold, and the prices that should be charged, in each market.

Calculate the price elasticities of demand in each market and discuss these in relation to the prices to be charged in each market.

Add a short note to GGC management outlining any reservations and qualifications you may have concerning your price recommendations.

In this assignment, you will investigate the biotic and abiotic structure and function of an ecosystem.

Choose one of the following ecosystems:

• Tropical rainforest
• Grassland
• Coral Reef
• Estuary
• Desert

You will write a two to three page APA-style research paper about your choice of ecosystem including:

• Where might this type of ecosystem be located? Give one specific example.
• Describe the structure of the ecosystem: List both the abiotic components and biotic components
• Describe the function of the ecosystem: How do the abiotic and biotic components interact in biogeochemical cycles? Describe both the carbon and nitrogen cycles
• Describe disturbance and recovery: Describe one natural and one human caused disturbance to the ecosystem. Explain the damage to the ecosystem, including how the abiotic and biotic characteristics of the ecosystem changed.
• Explain how ecosystems recover naturally based on resilience mechanisms and the theory of secondary succession.

2. In order to complete this discussion board assignment, review the occurrences at Easter Island and use this situation as a case study of poor stewardship that resulted in lack of sustainability. A discussion of Easter Island may be found in Unit 5 section of the Interactive Learning Materials area of the classroom.

Define stewardship and define sustainability. Then, select either the Amazon Rainforest (deforestation is the issue) or Bridger Teton National Forest located in Western Wyoming (possible oil drilling).

Discuss stewardship and sustainable resource use. In your discussion, describe the issues or potential problems. What are the environmental implications of deforestation if you choose the Amazon for your discussion? What are the ramifications of drilling for oil in Bridger Teton National Forest if this is your topic selection?

Can either area be conserved through wise use or should segments be preserved without any use?
