Firewall Security Explained | Types, Filtering, NGFW, DMZ & Port Forwarding — Lesson 14

Welcome to Lesson 14 of our Cybersecurity & Ethical Hacking Exam Prep series!
This lesson is all about Firewalls — the first line of defense in network security. We explore what they are, how they evolved, different types, filtering techniques, segmentation, and how to configure them safely.

Essential knowledge for certifications like CEH, CompTIA Security+, Pentest+, and for real-world cybersecurity professionals.

01:17 – Chapter 93: Proxy Firewalls, Application Firewalls & Next-Generation Firewalls (NGFWs)
How proxies and application firewalls work, and why NGFWs are today’s enterprise standard.

01:42 – Chapter 94: Network Segmentation with Firewalls
Security zones, DMZs, VLANs, subnets, and micro-segmentation for Zero Trust architecture.

02:00 – Chapter 95: Port Forwarding & Port Triggering

✅ Why watch this video?
• Understand how firewalls evolved from basic packet filters to modern NGFWs.
• Learn the different firewall types and when to use them.
• See how segmentation & DMZs protect against lateral movement.
• Master port forwarding & triggering to safely expose services.

⚡ Pro tip: Firewalls are powerful, but only as strong as their rules. Always apply the principle of least privilege and log everything.
