Setting Up Your Own Network Configuration Scavenger Hunt

Creating a successful scavenger hunt requires careful planning and execution. Here's a step-by-step guide to help you design and implement your own 4-3 Activity.

1. Defining the Scope and Objectives

Before diving into the details, clearly define the scope of the scavenger hunt. What specific network technologies or concepts do you want participants to focus on? What are the learning objectives you hope to achieve?

Examples of Scope and Objectives:

Scope: IP Addressing and Subnetting
- Objectives: Participants will be able to identify IP addresses, subnet masks, default gateways, and network addresses. They will understand how to calculate subnet sizes and determine usable IP address ranges.
Scope: Routing Protocols (e.g., OSPF, RIP)
- Objectives: Participants will be able to analyze routing tables, identify routing protocols in use, and troubleshoot routing issues.
Scope: DNS Configuration
- Objectives: Participants will be able to locate DNS server addresses, understand DNS record types (A, CNAME, MX), and troubleshoot DNS resolution problems.
Scope: Network Security (e.g., Firewalls, ACLs)
- Objectives: Participants will be able to identify firewall rules, analyze Access Control Lists (ACLs), and understand basic network security principles.

2. Choosing Your Network Environment

The scavenger hunt can be conducted in a simulated or a real network environment. Each approach has its advantages:

Simulated Environment:
- Pros: Safe, controlled, allows for experimentation without impacting a live network, easier to customize.
- Tools: Packet Tracer, GNS3, VirtualBox (with virtual network devices)
Real Network Environment:
- Pros: Provides real-world experience, exposes participants to the complexities of a live network.
- Cons: Requires careful planning to avoid disruptions, may be subject to security restrictions, requires more experienced participants.

If using a real network, ensure you have the necessary permissions and that all activities are conducted ethically and legally.

3. Crafting the Clues

This is where the creativity comes in! Each clue should lead participants closer to the final objective while requiring them to apply their networking knowledge.

Clue Types:

Configuration File Analysis: Provide snippets of configuration files (e.g., router configs, firewall rules) and ask participants to extract specific information.
- Example: "In the router configuration, find the IP address of the interface connected to the sales department network."
Network Command Output: Provide output from network commands (e.g., ipconfig, ifconfig, traceroute, ping) and ask participants to interpret the results.
- Example: "Analyze the output of traceroute www.example.com. Which hop represents the default gateway?"
Network Documentation: Hide clues within network diagrams, IP address spreadsheets, or standard operating procedures.
- Example: "According to the network diagram, what is the VLAN ID assigned to the wireless network?"
Physical Location: In a real network, clues can be hidden in specific locations (e.g., a server room, a network closet).
- Example: "Find the network switch in the server room. The next clue is written on a label attached to port 24."
Network Monitoring Tools: Require participants to use network monitoring tools (e.g., Wireshark, SolarWinds) to capture and analyze network traffic.
- Example: "Use Wireshark to capture DNS traffic. What is the IP address of the DNS server being used?"

Clue Design Principles:

Relevance: Clues should be directly related to the learning objectives.
Difficulty: Adjust the difficulty of the clues based on the participants' skill level. Start with easier clues and gradually increase the complexity.
Clarity: Clues should be unambiguous and clearly worded. Avoid using jargon or technical terms that participants may not understand.
Engagement: Make the clues interesting and engaging to keep participants motivated. Consider incorporating humor or real-world scenarios.

4. Setting Up the Network Infrastructure

Whether you're using a simulated or real network, ensure that the infrastructure is properly configured and accessible to the participants.

Considerations:

IP Addressing: Assign IP addresses to all devices and ensure that they are properly configured for routing and connectivity.
Routing: Configure routing protocols (if applicable) to allow traffic to flow between different network segments.
DNS: Set up DNS servers to resolve domain names to IP addresses.
Security: Implement basic security measures to protect the network from unauthorized access.
Accessibility: Ensure that participants have the necessary credentials and access rights to access network devices and tools.

5. Creating the Scavenger Hunt Flow

Plan the sequence of clues and the overall flow of the scavenger hunt. You can create a linear path where each clue leads directly to the next, or you can create a more complex branching path with multiple possible routes.

Tips for Creating a Good Flow:

Start Simple: Begin with an easy clue to get participants started and build momentum.
Vary the Clue Types: Use a variety of clue types to keep participants engaged and challenge different skills.
Provide Hints: Offer hints or clues for teams that are struggling to solve a particular clue.
Set Time Limits: Impose time limits for each clue or for the entire scavenger hunt to add a sense of urgency.
Designate a "Check-In" Point: Have teams check in at a designated point after solving each clue to ensure they are on the right track.

6. Testing and Refinement

Before launching the scavenger hunt, thoroughly test it to ensure that all clues are accurate, the network infrastructure is working correctly, and the flow is logical.

Testing Steps:

Solve the Scavenger Hunt Yourself: Go through the scavenger hunt from start to finish to identify any potential problems or ambiguities.

A user is reporting that they are receiving an incorrect IP address on the network, indicating the presence of a rogue DHCP server. Your team's mission is to locate and identify the rogue DHCP server.

Scope: DHCP, Network Traffic Analysis, IP Addressing

Objectives:

Participants will be able to identify DHCP traffic on the network.
Participants will be able to analyze DHCP packets to identify the rogue server.
Participants will understand how to locate the physical location of the rogue server.

Clues:

Clue 1 (Network Diagram): "Start by examining the network diagram located in the training room. Identify the network segment where the affected user is connected. This segment is likely where the rogue DHCP server is located." This requires participants to locate and interpret the network diagram.
Clue 2 (Wireshark Capture): "Use Wireshark on a computer in the affected network segment to capture DHCP traffic. Filter for DHCP Discover, Offer, Request, and ACK packets. Analyze the DHCP Offer packets. The IP address of the rogue DHCP server will be in the 'Server Identifier' field." This requires participants to use Wireshark and understand DHCP packet structure.
Clue 3 (Switch Port Mapping): "Now that you have the IP address of the rogue DHCP server, use the switch management interface to find the MAC address associated with that IP address. Then, determine which port on the switch the rogue DHCP server is connected to. The command show mac address-table address <MAC_Address> will be helpful." This requires participants to use switch management tools.
Clue 4 (Physical Location): "The switch port you identified is located in wiring closet B. Go to wiring closet B. The rogue DHCP server is a Raspberry Pi disguised as a power adapter. The final clue is taped to the device." This requires physical investigation and completes the scavenger hunt.
Final Clue: "Congratulations! You found the rogue DHCP server. The administrator has been notified. You've successfully completed the Network Configuration Scavenger Hunt!"

Debriefing:

Review the steps taken to identify the rogue DHCP server.
Discuss the importance of DHCP security and the risks of rogue servers.
Explain how to prevent rogue DHCP servers using techniques like DHCP snooping.
