Corso Programmazione e Sicurezza delle Reti - Materiale Didattico Open Source

The Genesis of the Project: From a Passion for Security to Sharing

Professor Davide Quaglia’s Programming and Network Security course was much more than a simple university exam for me. It was an opportunity to delve deeper into a field that deeply fascinates me: cybersecurity and network technologies.

From the very first lessons, I realized that this topic required both a theoretical and an intensely practical approach. Many of my classmates struggled to connect theoretical concepts with real-world implementations, often getting lost in socket programming, network protocols, and traffic analysis.

From Shared Difficulty to Collaborative Solution

Observing my colleagues’ difficulties, I decided to transform my study program into a shared resource for the entire student community. The idea was simple yet ambitious: to create a comprehensive collection of materials that could help anyone approach this exam with greater confidence.

It wasn’t just about sharing notes, but about building a complete educational ecosystem with:

• Practical, commented code
• Working examples
• Clear documentation
• Analysis of real-world cases
