DAY 12 NETWORK SECURITY FUNDAMENTALS PART 2

Master Network Security: Linux Firewalls, Nginx & Ports! 🛡️💻 Welcome to Day 12 of our Cybersecurity journey! We have covered the foundations, and now it’s time to move from theory to practice. In this session, we dive deep into a live Linux environment to understand how network security is implemented on real-world servers. We’ll walk through service management, port configuration, and the professional tools used to defend infrastructure, including UFW and Nmap. 📍 Video Chapters: 0:00 - Introduction & Recap: Transitioning to Practical Security 05:10 - Deep Dive: What are Network Ports?
