You are given an Option A or B. Choose one to complete for Assignment 1.
Option A –
Examine the Physical Connectivity of a Network Using a Network Mapping Tool
Nmap is a network utility used by network administrators, hackers, and forensic scientists alike for information discovery and gathering. Information can include the network’s topology, systems, and possible vulnerabilities that would allow a malicious user to gain access to a system. To complete the following lab, connect to a LAN (wireless or wired connection, either is fine) where multiple nodes are connected. Public Wi-Fi hotspots are a good option, such as a library or coffee shop, as the topology and the nodes are unknown. Ensure that there are at least five other nodes connected to the network.
- Determine and make note of your IP address. This can be accomplished by opening a command prompt window (or terminal) or via the control panel (or settings panel). There are many ways to find this information—the specific method is dependent on your operating system. Take a screenshot of the window showing your IP address.
- Download and install Nmap. Open Nmap and conduct a Quick scan to determine the basic topology of the LAN. Enter your IP address into the Target field and append a /24 (forward slash twenty-four) to the IP address.
- Take a screenshot of Nmap.
- Describe the meaning and implications of adding /24 to the IP address target.
- Click the Scan button and allow the network scan to complete. You will see the message Nmap done in the Nmap Output window. Take a screenshot of Nmap showing the Output window.
- Determine the network topology.
- What is its configuration?
- List the total number of connected clients, IP Address, MAC Address, and the latency of each. You should consider the router as well—remember that it has different interfaces on different subnets. Be sure to identify them.
- Which IP Addresses correspond to network devices (OSI Layer 3 and below)? Describe the type of network device and its purpose.
- Change the profile to Intense scan and click the Scan button. Take a screenshot of the Nmap Output window.
- Identify the OSs of each operational node.
- How is OS fingerprinting accomplished, and why is it important?
- Confirm your initial topology conclusion. What other topologies could the network have?
- Sketch the network topology. Be sure to identify each node’s IP, OS, Type, NIC, and highest OSI Layer capability. If there are wireless nodes on the network, be sure to identify the protocol being used.

Option B—Compare Network Mapping Tools (5 Points)
For this option, you will research three network mapping tools. Create a 2- to 3-page report and address the following:
- Explain what a network mapping tool is and how it is used in organizations.
- At a high level, describe how each of your chosen tools work. How are they similar? How do they differ?
- Create a table where you compare and contrast each tool in terms of functionality, advantages, disadvantages, etc.
- Make a final recommendation for the tool you think is most effective. Be sure to justify your choice.
Your paper should demonstrate thoughtful consideration of the ideas and concepts presented in the course and provide new thoughts and insights relating directly to this topic. Your response should reflect scholarly writing and current APA standards. Be sure to adhere to Northcentral University’s Academic Integrity Policy.
