The document contains instructions for several assignments for a network security course. The first assignment asks students to summarize how they would hack into a nefarious business's network as an ethical hacker to find evidence in their database, while remaining anonymous. The second assignment involves designing a secure network diagram for a company with offices in Chicago and a remote site, incorporating defense in depth principles. The third assignment asks students to improve an existing network diagram by adding devices like servers, firewalls, and IDS systems.

Case Study: The Ethical Hacker
Due Week 3 and worth 70 points
Imagine for a moment that you are a hacker; an ethical one. You are
called upon by law enforcement based on your expertise to hack into a
network of a business known to be launching crimes against humanity as
its primary mission for operation and capital gain. Assume you are not to
be concerned with any politics of the job and your actions are legal and
ethically justified. This nefarious business takes its own security
seriously and therefore has implemented several forms of network
security such as firewalls, Web proxies for its Web gateways, and VPNs
for remote users. You also know that this business exists much like any
normal corporation, renting several floors of office space to
accommodate between 100-200 employees. Also imagine that the
business’s entire network topology is located in that same location. Your
goal is to infiltrate the security enough to find evidence included in the
local MSQL database. You need to remain anonymous and operate
within the reasonable parameters of the law.
Write a four to five (4-5) page paper in which you:

2. Explain your method of attack and operation within reasonable
parameters of the law.
Discuss specific malware, social engineer, or any other type of attacks
you would deploy to achieve your desired goals.

20 employees who need access to all resources at corporate plus the
Internet
Connection to the Internet (3mbps)

Assignment 2: Mister Network Engineer
Due Week 8 and worth 70 points
Using the network diagram below, your task is to incorporate the

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
user534@yahoo.com. 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.

10. 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:

Switches (and / or hubs)
Local users
Remote users
Workstations
Files share (i.e. CIFS)

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.

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 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,

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.
