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:

o
Follow the access, core,
distribution layer model.

o
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:

o Local
user sends email to a Yahoo recipient. Local (corporate) user having email
[email protected]
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:

o 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 toftp.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:

o 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.
