[Get Answer ]-Term Paper Project Designing A Secure Network 2

Question Description

This term paper involves putting together the various concepts learnedthroughout this course. You are tasked with designing the most securenetwork possible, keeping in mind your goal of supporting three (3) ITservices: email, file transfer (centralized), and VPN. Your first stepis to design a single network capable of supporting there three (3)different services. Once you have fully designed your network, you willneed to provide three (3) workflow diagrams explaining how your designednetwork handles the three (3) different transactions. The first is aninternal user sending an email using his / her corporate email addressto a user on the Yahoo domain with an arbitrary address ofuser534@yahoo.com. The second workflow diagram should show a userinitiating an FTP session from inside your network to the arbitrary siteof ftp.netneering.com. The third workflow is an externally locatedemployee initiating a VPN session to corporate in order to access fileson the Windows desktop computer, DT-Corp534-HellenS, at work.

  • 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

  • UsingMicrosoft Visio or its open source alternative, create a diagramshowing the overall network you’ve designed from the user or endpointdevice 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 jonny.hill@Corp534.com sends an email to user534@yahoo.com.
      • Documentand label the diagram showing protocols and path of the data flow asdata traverses through your network from source to destination. 
      • Includepath 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 directorycredentials to authenticate to the ftp server (linux running Redhat) onthe DMZ. He needs to transfer files from his desktop across the Internetto ftp.netneering.com.
      • Documentand label the diagram showing protocols and path of the data flow asdata traverses through your network from source to destination. 
      • Includepath 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:
    • Remoteuser, Hellen Stover, connects via VPN from home through the Internet toher corporate desktop, DT-Corp534-HellenS. Hellen uses a browser toinitiate her VPN connection. By browsing to https://VPNaccess.corp534.com,she arrives at a login page where she needs to authenticate using herActive Directory credentials before the VPN tunnel is built.
  • Documentand label the diagram showing protocols and path of the data flow asdata traverses through your network from source to destination. 
  • Includepath 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

  • Useat 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:

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

The specific course learning outcomes associated with this assignment are:

  • Explainthe 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.
  • Writeclearly and concisely about Advanced Network Security Design topicsusing proper writing mechanics and technical style conventions.
