Curriculum

Introduction to Network Security & Wireshark

This introductory section lays the groundwork for your Wireshark journey. The "What is Ethical Hacking and Network Security" lecture provides a foundational understanding of cybersecurity principles. We then delve into the "OSI Model," a crucial concept for comprehending network communication and troubleshooting. This section equips you with the essential context for effective packet analysis.

Fundamentals of Packet Analysis and Networking

Here, we establish the core principles of packet analysis. You'll explore the "What, Why, and When's of Packet Analysis," clarifying its purpose and application in network diagnostics. Lectures on "Understanding Layer 1, 2, and 3 - Hubs, Switches, and Routers" and "Traffic Classifications" provide the context for understanding network architecture and traffic patterns. This section prepares you for hands-on analysis.

Mastering Network Sniffing Techniques

This section delves into network sniffing, a critical skill for network monitoring and security analysis. You'll learn "How Packet Analysis Works," then explore the practical aspects of sniffing in different network environments ("Hubs are best for us but everyone is using Switches") and master "How To's of Network Sniffing." You'll gain valuable expertise in capturing network traffic.

Getting Started with Wireshark: Installation & Configuration

This section is dedicated to setting up Wireshark across various operating systems. Learn why Wireshark is the industry standard ("Why everyone is using Wireshark") and master the installation and configuration process for Windows, Linux, and macOS. Lectures on Wireshark installation and configuration for each OS are provided. You will also learn about integrated vs. external Wi-Fi adapters and "Customizing Wireshark" to optimize your workflow.

Capturing & Analyzing Packets with Wireshark

This section focuses on mastering Wireshark's packet capture and analysis capabilities. You'll learn how to "Save and Merge Packets," utilize powerful filtering techniques ("Starting with Filters in Wireshark," "Capture Options," "Capture Filters," "Display Filters"), and effectively manage capture settings. These skills are central to efficient packet analysis.

Command-Line Packet Analysis with TcpDump & Tshark

Expand your skillset by mastering command-line packet analysis tools. This section covers the installation and usage of "TcpDump and Tshark," providing you with alternative approaches to network monitoring and analysis. You’ll gain proficiency in utilizing these powerful command-line tools.

Deep Dive into Network Layer Protocols

This section provides an in-depth understanding of essential network protocols. You will explore the inner workings of ARP, IP, TCP, UDP, DHCP, and HTTP, learning about their structures and communications patterns. Detailed packet analysis examples are included for TCP, UDP, DHCP and HTTP, providing real-world insights and practical applications of your learned skills.

Advanced Packet Analysis Techniques

This final section emphasizes practical application and advanced techniques. The "Packets don't lie" lecture summarizes the importance of careful observation and analysis of packet data to arrive at accurate conclusions.
