To get the most out of this book

You should have a basic understanding of the Linux, basic commands, tools like Git and a text editor like vi.

The book chapters contain both theory and hands-on exercises. We feel that the exercises help to reinforce the theory, but they are not required to understand each topic. If you want to do the exercises in the book, you will need to meet the requirement in the table below.

Requirements for the chapter exercises.	Version
Ubuntu Server	20.04 or higher

All exercises use Ubuntu, but most of them will work on other Linux installations. Chapter 10, Auditing using Falco, DevOps AI, and ECK has steps that are specific to Ubuntu and the exercise will likely fail to deploy correctly on other Linux installations.
