A Practical Introduction
The Fundamental Theory
Palo Alto is a next-generation firewall. This means that it uses more advanced techniques to detect threats compared to a traditional firewall. Where a more traditional firewall would inspect source and destination IP addresses and ports, a next generation firewall would detect an application, user, or piece of content. From there we can choose to either allow, block, drop or reset the connection.
Chapter Navigation
Every lab will contain a learning outcome section on the top. Here is an example:
Learning Objectives
- Learn how to navigate this book
- Open up GNS3
These will contain what the current lab is trying to teach.
A topology of how the lab will look like, will be displayed after the learning outcomes. Here is an example:
A Practical Introduction
What this book aims to accomplish is a practical understanding of the usage and functionality of Palo Alto firewalls. Learn by doing will be a strong driving force in the coming labs and examples in this book, and I encourage you to try and extend these labs and have fun with them.
