Assignment 1- Defense in Depth

Due Week 5 and worth 80 points
Oftentimes, the process of implementing security opens one's eyes to other forms of
security not previously considered. 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 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:
o All network devices used (routers, switches, hubs, firewalls, VPNs, proxies, and/or
others)
o The interconnections between network devices
o The end user (client) devices (desktops, laptops)
o The Internet cloud, generically, to represent your network's interface to the Internet
2. Describe the flow of data through your network, and explain how your network design provides
multiple layers of security.
3. Use at least four(4) quality resources in this assignment. (Note: Wikipedia and similar websites
do not qualify as quality resources.)
4. 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.
Your assignment must follow these formatting requirements:
1. Use proper APA format.
2. 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 (if applicable) 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.
 Identify network security tools and discuss techniques for network protection.
 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.
