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:
1. Explain your method of attack and operation within reasonable
parameters of the law.
2. Discuss specific malware, social engineer, or any other type of
attacks you would deploy to achieve your desired goals.
3. Assess the hurdles you expect and how you plan to overcome
them.

2. 4. Determine how you would remain anonymous without blowing
your cover.
5. 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.
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.
 Explain the concepts of network security and associated ethical
issues in addressing exploits.
 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.

Assignment 1: Defense in Depth
Due Week 4 and worth 70 points
Oftentimes, the process of implementing security opens one’s eyes to
other forms of security they hadn’t thought of previously. Well, in this
assignment you should experience just that. This assignment focuses
on a model of implementing security in layers which in many cases
requires a network that is designed accordingly. In this assignment,
you are to design a network to incorporate the following:
Corporate Site (Chicago)
 All servers exist here (Web server, file server, print server, mail
server, ftp server)
 Connection to the Internet (50mbps)
 300 employees who only need access to local corporate
resources and the Internet
1 Remote Site (8 miles away)
 20 employees who need access to all resources at corporate plus
the Internet
 Connection to the Internet (3mbps)
Write a four to five (4-5) page paper in which you:
1. Using Microsoft Visio or its open source alternative, design a
network diagram, particularly with defense in depth in mind
which depicts:
1. All network devices used (routers, switches, hubs,
firewalls, VPNs, proxies, and / or others)
2. The interconnections between network devices
3. The end user (client) devices (desktops, laptops)

4. 4. The Internet cloud, generically, to represent your
network’s interface to the Internet
Note: The graphically depicted solution is not included in the required
page length.
1. Describe the flow of data through your network, and explain
how your network design provides multiple layers of security.
2. 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.

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

8. 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.

following three (3) Parts. Note: Please use the following page
breakdown to complete your assignment:
