Introduction To Network Firewalls

What you’ll learn
What firewalls are and their role in securing networks.
The difference between hardware, software, and virtual firewalls.
A detailed comparison of different firewall types, such as packet-filtering, stateful inspection, next-generation firewalls (NGFW), and proxy firewalls.
How to configure firewall rules and understand their importance in controlling network traffic.
The role firewalls play in securing site-to-site and client-to-site VPN connections.
Exploring additional firewall services such as botnet protection, DNS filtering, and intrusion prevention systems (IPS).
Applying firewall concepts to real-world network environments.

Requirements
Familiarity with fundamental networking concepts like IP addresses, ports, and protocols (such as TCP/IP) will be helpful.
No advanced knowledge is required, but having an interest in how networks are secured will enhance the learning experience.
This course is designed for beginners, so no prior experience with firewalls is necessary. All topics will be explained from the ground up.

Description
In today’s digital world, securing networks is more important than ever. Firewalls are a critical line of defense in network security, protecting sensitive data from threats and unauthorized access. In this “Introduction to Network Firewalls” course, you will gain a solid understanding of firewalls and how they help secure modern networks.Designed for beginners and those new to network security, this course covers the fundamental concepts of firewalls, including their purpose, types, and how they operate within a network. We’ll explore the differences between hardware, software, and virtual firewalls, giving you a clear understanding of which firewall solution best fits various environments. You will also dive into firewall rules and policies, learning how to configure them to manage traffic effectively and ensure a secure network perimeter.In addition, the course provides insights into Virtual Private Networks (VPNs), including site-to-site and client-to-site VPN configurations, and how firewalls play a critical role in securing these connections. We’ll also explore advanced firewall services such as botnet protection, DNS filtering, and intrusion prevention systems (IPS), offering a complete view of the comprehensive security features modern firewalls provide.Whether you’re an aspiring IT professional, a small business owner, or simply someone curious about network security, this course will equip you with the knowledge needed to understand and manage firewalls confidently. By the end of the course, you’ll have a practical understanding of how firewalls function, enabling you to make informed decisions about your network’s security and protect it from potential threats.Take the first step in mastering network security—enroll today and start learning how firewalls can safeguard your systems!
