Network Packet Capturing and Protocol Analysis

This repository documents my hands-on work exploring network protocols, traffic behavior, and simulated attack scenarios. As part of my cybersecurity training, I designed and executed packet-level experiments using tools like Scapy, Wireshark, and raw Python sockets to build a strong foundation in traffic analysis and threat detection.

Overview

The materials in this repository reflect practical skills in:

• Crafting and sending TCP/UDP packets manually
• Capturing and inspecting network traffic
• Simulating common attacks (e.g., Smurf, Teardrop, WiFi jamming)
• Analyzing port scanning techniques and response patterns
• Understanding session persistence and HTTP behavior
• Investigating wireless authentication events (WPA2 handshake)

Each file includes a step-by-step breakdown of the problem, the approach taken, tools used, packet-level results, and final observations.

Skills Demonstrated

• Low-level network traffic creation and inspection
• Manual attack simulation and analysis
• Threat detection aligned with MITRE ATT&CK techniques
• Strong familiarity with Scapy, Wireshark, tcpdump, and Python for networking
• Clear documentation and interpretation of results

Purpose

This repository is intended to showcase my capability to go beyond surface-level security knowledge and work directly with packets, protocols, and simulated adversarial behavior. It’s a reflection of my commitment to understanding how attackers operate and how defenders can better detect and prevent such threats at the network layer.

About Me

I’m a cybersecurity graduate and hands-on learner focused on DevSecOps, threat detection, and security automation. This project is part of my personal initiative to build a strong technical portfolio that reflects my readiness for real-world security roles.
