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
