Welcome to Module 2 of your cybersecurity training! 

In this module, we'll embark on a detailed exploration of network protocols, with a special focus on the TCP/IP stack and its vulnerabilities. You’ll also learn advanced packet analysis techniques using powerful tools like Wireshark and Scapy.

2.1 TCP/IP Stack and Protocols

The TCP/IP stack is the cornerstone of modern networking, enabling communication across diverse networks. Understanding this stack is crucial for identifying and mitigating network vulnerabilities.

What is the TCP/IP Stack?

The TCP/IP (Transmission Control Protocol/Internet Protocol) stack is a set of protocols that allows computers to communicate over a network. It's the protocol suite used by the internet and most local networks.

The TCP/IP stack is divided into four layers

, each responsible for specific functions that ensure data is transmitted accurately and efficiently.
