[Solved] Network Engineer

Assignment Prompt & Instructions

## **Introduction**

In this three-part assignment, you will design a secure network infrastructure.

The specific course learning outcome associated with this assignment is:

– Plan a deployment of software and/or hardware, including implementation and testing considerations.

## **Instructions**

### **Part 1**

Use Microsoft Visio or an open-source alternative to:

– Create a network infrastructure diagram, incorporating the following devices needed for a secure corporate network, placed where they will work, and citing specific, credible sources that support the design. **Note:** A web search will provide multiple examples of network infrastructure diagrams.

– Web server.
– FTP server.
– VPN server.
– Authentication server.
– Anti-virus server (client-based and server-based).
– Edge firewall.
– Firewall.
– Vulnerability scanner.
– Intrusion detection system (IDS).
– Web proxy.
– Edge router.
– Core router.
– Switch.
– Distribution router.

**Note:** All client-and server-based devices work where a client is installed on a workstation, which has bi-directional communication with a corresponding server.

### **Part 2**

Write a 6-10 page paper in which you:

– Determine the specific devices you will use in the network, including the following information for each device:
– Make or vendor's name (for example, Microsoft, Redhat, Cisco, Juniper, Netgear, 3Com).
– Model (for example, Windows 7, ASA 5500, Cisco 3500, Squid).
– IP address assigned to all devices.
– Determine the basic configuration of each network device, citing specific, credible sources that support the configuration.
– Research each of the devices you chose and provide a basic configuration you would use in your network.
– Use IP addresses to describe your configuration.
– Identify the operating system.
– Highlight at least five security features and the administrative controls incorporated into each device, including devices in the network diagram.
– Explain the impact that each of your configurations has on the security of the entire network.
– Explain the elements that must be addressed for planning and testing a network, citing specific, credible sources that support your assertions and conclusions.
– Organizational requirements and expectations.
– Budget.
– Modularity for security and testing.
– Naming conventions that facilitate layering and growth.
– Determination of required network speed and data capacity.
– Vendor support.
– Determination of risk and redundancy.
– Uptime requirements.
– Continuous data monitoring for fault, failure, or security-induced changes.
– Load balancing.
– Testing for latency.
– Bandwidth.
– Throughput.
– Specific software and tools.
– 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).

### **Part 3**

Use Microsoft Visio or an open-source alternative to:

– Update your initial diagram to create a final network diagram, incorporating at least four-fifths of the devices needed for a secure corporate network and citing specific, credible sources that support the design. Be sure to include vendor information, model information, and IP addresses. In addition, ensure that:
– VPN sessions (from a laptop) are only allowed to access the desktops in the IT department by IT department employees.
– All VPN connections from the Internet cloud into the corporate network terminate at the VPN server.
– Users from Engineering and Finance and Accounting cannot communicate.
– Vulnerability scans occur daily, with all desktops scanned at least once per day.

### **Submission Requirements**

All diagrams and charts you create for the assignment should be included in the paper.
