Part 21, 🔐 INTRODUCTION TO NETWORK SECURITY | Firewalls & AAA Explained 🚨🔥

The internet is not friendly. Every second, networks are being scanned, attacked, and exploited — and firewalls and AAA are the first line of defense. In this hands-on lab video, I break down Network Security fundamentals, focusing on: 🔥 Firewalls 🔐 AAA – Authentication, Authorization, Accounting 🚀 What you’ll learn in this video: Why network security is non-negotiable How firewalls inspect and control traffic Packet filtering vs Stateful vs Application firewalls Why firewalls block traffic by default How AAA controls who can access network devices Authentication (Who are you?) Authorization (What are you allowed to do?) Accounting (What did you do?) 💡 Think of network security like a high-security building: Locks, guards, cameras, access badges — all working together to protect what matters.
