Annotated Bibliography

The purpose of the annotated bibliography is to assist you in developing research analysis skills including critical thinking, writing, and literature research skills. The annotated bibliography should include a paragraph for each source containing the following information:

• Name of the article, including the complete bibliographic citation, using APA format.
• Summary/abstract of the article – annotation (sometimes it is helpful to ask yourself the following questions in synthesizing the information:
  • Who? (author)
  • What was done? (e.g., an experimental study investigating the interaction of short term memory and attention)
  • How? (was it done)
• What were the findings? (identify the major ones)
• Contributions? (new findings, applications, etc.)

Review the complete instructions for the Final Paper in Week Five. To conduct accurate research for the annotated bibliography, consider the following:

• Research in peer-reviewed journals or other journals that are considered to have reliable information (do not use sources from the secular press (e.g., Time, Newsweek, or Wikipedia). Review the guidelines for acceptable sources by reading the “Academic Research” section within the Student Responsibilities and Policies tab under Course Home on the left navigation toolbar in your online course.
• Identify at least ten academic sources at least six of which can be found in the Ashford Online Library. If you do find something on the World Wide Web, it must be authored and be a reliable source.
• In these journals, the research and information is either reviewed by an editorial team (such as for the Academy of Management Review) or a group of peers (such as in many journals you find through the Ashford Online Library).

For information regarding the annotated bibliography, refer to the Sample Annotated Bibliography found in the Ashford Writing Center within the Learning Resources tab on the left navigation toolbar.

You must use at least ten scholarly sources (at least six of which can be found in the Ashford Online Library) other than the textbook. The descriptions for each source must be at least one paragraph in length. For information regarding APA samples and tutorials, visit the Ashford Writing Center, within the Learning Resources tab on the left navigation toolbar

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 tohttps://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.

A selfless person approaches Jones and Smith with a $100 bill and offers to sell it to the highest bidder, but both the winning and losing bidders must pay her their bids. So if Jones bids $2 and Smith bids $1 they pay a total of $3, but Jones gets the money, leaving him with a net gain of $98 and Smith win -$1. If both bid the same amount, the $100 is split evenly between them. Assume that each of them has only two $1 bills on hand, leaving three possible bids: $0, $1, or $2. Write out the payoff matrix for this game, and then find its Nash equilibrium.
