Network Traffic Simulation using Scapy

Overview

This project demonstrates the generation of network traffic in a controlled lab environment using Python and Scapy. It includes:

• TCP SYN packet burst simulation
• UDP traffic generation with random payloads
• Use of randomized IPs and ports to mimic real-world traffic patterns

The project is strictly designed for educational and cybersecurity lab use only.

Disclaimer

This project must only be executed in:

• Isolated virtual environments (e.g., Kali Linux + Metasploitable)
• Authorized lab setups

Unauthorized use on public networks is illegal.

Technologies Used

• Python 3
• Scapy
• Kali Linux (recommended)
• VirtualBox / VMware

Features

1. TCP SYN Burst Simulation

• Generates TCP SYN packets
• Randomizes source IP and port
• Simulates traffic bursts with delay control

2. UDP Traffic Generator

• Sends UDP packets with random payload
• Uses randomized ports and IP addresses
• Helps in traffic pattern observation
