Network Fundamentals & Security Exploits

A journey from packets to exploits.

This book bridges the gap between understanding how networks work and discovering how they break. Part one builds a solid foundation in networking—from the OSI model and TCP/IP stack to routing protocols and wireless communications. Part two takes that knowledge further, exploring real-world vulnerabilities across every layer: ARP spoofing, IP fragmentation attacks, TCP exploits, application-layer threats, and beyond.

Whether you're a developer seeking to write more secure code, a student preparing for a career in cybersecurity, or a curious technologist wanting to understand the invisible infrastructure of the internet, this book provides the clarity and depth to see networks as both systems of connection and surfaces of attack.

Learn how data flows. Understand where it fails.
