🌱 How to start this project?

Download here the file and open it with Packet Tracer.

Once you have opened the file with Packet Tracer you will see the floating window with the instructions to follow.

📝 Instructions

Create a simulated network environment that includes a Demilitarized Zone (DMZ), configure firewalls, gateways, and network detection systems, and ensure network security.

Components:

  1. Network Design:

    • Design a network layout that includes a DMZ, internal network, and external network.
    • Set up virtual machines or use a network simulation tool to create the network environment.
  2. Firewall Configuration:

    • Configure firewalls to segment the network into DMZ and internal networks.
    • Set up firewall rules to control traffic between the internal network, DMZ, and external network.
  3. DMZ Setup:

    • Deploy services in the DMZ such as a web server, mail server, or DNS server.
    • Ensure that the DMZ is isolated from the internal network but still accessible from the external network.
  4. Gateway or Proxy Server:

    • Configure a gateway or proxy server to manage traffic between the internal network and the external network.
    • Implement access control policies on the proxy server.
  5. Network Detection and Response (NDR):

    • Deploy and configure NDR tools to monitor network traffic and detect suspicious activities.
    • Set up alerts and logging for network events.
  6. Security Testing:

    • Perform network scans and vulnerability assessments using tools like Nmap to identify potential security issues.
    • Test the firewall rules and network segmentation to ensure that unauthorized access is prevented.
  7. Documentation and Reporting:

    • Document the network design, firewall rules, and security configurations.
    • Prepare a report summarizing the project, including any vulnerabilities discovered and the steps taken to address them.

This project will give participants hands-on experience with configuring and securing a network environment, applying the concepts of network defense, firewalls, DMZ, and network detection and response.

🚛 How to deliver this project?

Once you've finished the Packet Tracer instruction steps, please save your changes and attach the file to the 4geeks.com platform in the corresponding project.

  • Configuration of the Internal, External, and DMZ networks in the proposed network design.
  • Configuration of the firewall and gateway to control traffic between the internal, external, and DMZ environments.
  • Screenshots of access and traffic blocking tests between the specified environments.
  • Report detailing the proposed design's applied security measures and security recommendations.
