🧪 Network Lab Projects

Welcome to the Network Lab Projects repository! This is a collection of hands-on networking projects aimed at simulating and understanding key components of modern network infrastructures — from basic client-server communication to enterprise-grade security and monitoring systems.

🔍 Purpose

This repo serves as a practical lab environment to:

• Explore foundational networking concepts
• Simulate real-world office and enterprise network setups
• Learn and experiment with security mechanisms (e.g., firewalls, IDS/IPS, TLS interception)
• Build an end-to-end understanding of how networks operate and how to secure them

Each project is self-contained and comes with configuration files, documentation, and usage instructions.

📁 Project Structure

Below is a list of planned and ongoing projects. Each project resides in its own directory with detailed instructions.

✅ Basic Projects

• Client-Server File Sharing
  Simple TCP/UDP client-server applications for sending files across a network.

• Custom Firewall Implementation
  Using iptables/nftables or Python-based packet filtering to create and manage custom firewall rules.

🏢 Office Network Simulation

• Office Network Layout
  Simulating a small office network with routing, subnetting, and basic access control.

• User and Role-Based Access Control (RBAC)
  Implementing user zones and permissions across different network segments.

🏢🏢 Enterprise Network Simulation

• Traffic Monitoring & Analysis
  Using tools like Wireshark, tcpdump, Zeek, or ELK stack for network telemetry and deep packet inspection.

• TLS Interception with Custom CA
  Set up a trusted internal Certificate Authority to inspect encrypted HTTPS traffic securely.

• Intrusion Detection/Prevention Systems (IDS/IPS)
  Deploying Snort/Suricata for real-time threat detection.

• Network Zoning & VLANs
  Simulating DMZ, internal, and external zones with segmentation and VLAN tagging.

• Advanced Access Controls
  Integrating role-based access and ACLs for internal/external services.
