[Solved] Defense in Depth

Assignment Prompt & Instructions

## **Introduction**
The process of implementing security frequently opens one's eyes to other forms of security not previously considered. In this two-part 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.
The specific course learning outcome associated with this assignment is:
– Recommend best security practices to achieve business objectives based on risk assumptions.
## **Instructions**
Design a network that incorporates the following:
– One corporate site (Chicago).
– All servers exist here (web server, file server, print server, mail server, FTP server).
– Connection to the Internet (50 MBps).
– 300 employees who only need access to local corporate resources and the Internet.
– One remote site (8 miles away).
– 20 employees who need access to all resources at corporate, plus the Internet.
– Connection to the Internet (3 MBps).
### **Part 1**
Use Microsoft Visio or an open-source alternative, such as Dia Diagram Editor, to:
– Create a network diagram with defense in depth in mind, citing specific, credible sources that support the design and depicting at least four-fifths of the following:
– All necessary network devices (routers, switches and/or hubs, firewalls, VPNs, proxies, and others).
– The interconnections between network devices.
– Connections to end-user (client) devices (desktops, laptops).
– Connections from the Internet cloud to the network input.
### **Part 2**
Write a 6-10 page paper in which you:
– Describe the flow of data through the network, citing specific, credible sources.
– Assume data begins at the remote site.
– Data flow may be monitored by an IDS.
– Explain all three elements of the CIA triad and how isolating by network functions helps deliver a layered approach, citing specific, credible sources that support your assertions and conclusions.
– Support your main points, assertions, arguments, or conclusions with at least four specific and credible academic sources synthesized into a coherent analysis of the evidence.
– Cite each source listed on your source page at least one time within your assignment.
– For help with research, writing, and citation, access the [library](https://library.strayer.edu/) or review [library guides](https://library.strayer.edu/guides).
This course requires the use of Strayer Writing Standards (SWS). The library is your home for SWS assistance, including citations and formatting. Please refer to the [Library site](https://library.strayer.edu/sws) for all supports. Check with your professor for any additional instructions.
