To get the most out of this book

To follow all the topics we will be covering, it will be helpful if you have access to an up-to-date firewall and Panorama in a lab environment. Being able to spin up test devices that can serve as domain controllers, authentication servers, clients, Docker hosts, and generic web servers will be helpful with some of the more involved chapters. It will also allow you to test your new skills before implementing them in a production environment. Basic networking and system administration skills are required and a familiarity with Wireshark to analyze packet captures is helpful.

You will need an SSH- and TTY-capable client such as PuTTY or Terminal to access the command-line and console interfaces.

If you are using the digital version of this book, we advise you to type the code yourself or access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related to the copy/pasting of code.
