Network Packet Manipulation with Scapy: Sending and Analyzing Traffic

Understanding how data travels across a network is a fundamental skill for security enthusiasts, system administrators, and developers alike. Standard tools only show you the surface, but learning to construct and manipulate raw packets gives you complete control over your network traffic. In this course, you will transition from network basics to writing functional Python scripts using Scapy, the industry-standard packet manipulation library. You will learn to formulate custom requests, interpret responses, and diagnose network behavior at the protocol level. What you'll learn: Understand foundational TCP/IP suite concepts, packet headers, and network protocols; Craft custom TCP, UDP, and ICMP packets from scratch using Scapy syntax; Send packets and capture their responses to analyze network behavior; Apply modern Python practices, including type hints, to write clean and robust networking scripts; Analyze packet layers and payload data to troubleshoot communication issues; Practice safe and ethical network scanning and testing techniques in a controlled environment. You will start with core networking definitions and Scapy installation before moving on to practical packet crafting. Through clear written explanations and step-by-step code examples, you will build a solid foundation in network analysis. This course is designed for beginners interested in networking, cybersecurity, or systems administration. No prior experience with packet manipulation is required.
