Explain how to make the file transfer process more


Term Paper Project: Designing a Secure Network

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 assignment is all about designing a secure network. You are tasked by designing the most secure network possible; remember your goal of supporting 3 IT services: email, file transfer and VPN. Your main step is to design a single network capable of supporting there 3 dissimilar services. Once you have completely designed your network, you will require providing 3 workflow diagrams describing how your designed network handles the 3 dissimilar transactions. By using the Microsoft Visio or its open source alternative, make a diagram illustrating the overall network you have designed from the user or endpoint device to the Internet cloud and all in between, in which you: Question: Describe each and every network device's function and your particular configuration of each networking device. Question: Design and label the bandwidth accessibility or capacity for each and every wired connection.
