The Linux world is constantly changing, requiring new knowledge and skills to work as a Linux system administrator. Linux Fundamentals, Second Edition not only updates the first edition with new material, but also changes the book’s focus a bit, from a basic approach to Linux to a more advanced server-oriented look at using Linux. While the first edition tracked the skills needed to meet the LPI Linux Fundamentals exam requirements, this edition tracks the more advanced CompTIA Linux+ exam requirements. The Second Edition provides a soft, accessible, and practical introduction to Linux environments and command line basics. The addition of new virtual labs will also empower students to apply theory in hands-on exercises in real time. This edition dives deeper into the Linux server environment, covering the commands you are expected to know for the Linux+ exam.

This lab manual accompanies the textbook Linux Essentials for Cybersecurity, which teaches people how to use Linux systems and ensures that the Linux systems they work on are as secure as possible. To really become a Linux cybersecurity expert, you need practice. In this book, there are three different types of labs to practice your skills: Labs in which you are presented with a short problem that requires only a single operation to complete. Labs that are more complex but in which we provide you with a guide to perform each step, one at a time. Scenario labs in which you are asked to solve a problem entirely on your own. These labs are designed to pose a greater challenge. No matter the type, these labs are designed to be performed on live Linux systems to give you hands-on practice and develop critical thinking and complex problem-solving skills.
