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.
Linux is a Unix-like and mostly POSIX-compliant computer operating system (OS) assembled under the model of free and open-source software development and distribution. The defining component of Linux is the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. The Free Software Foundation uses the name GNU/Linux to describe the operating system, which has led to some controversy. Linux was originally developed as a free operating system for personal computers based on the Intel x86 architecture, but has since been ported to more platforms than any other operating system. Because of the dominance of Android on smartphones, Linux has the largest installed base of all general-purpose operating systems. Linux is also the leading operating system on servers and other big iron systems such as mainframe computers and virtually all fastest supercomputers, but is used on only around 2.3% of desktop computers when not including Chrome OS, which has about 5% of the overall and nearly 20% of the sub-$300 notebook sales.Linux also runs on embedded systems, which are devices whose operating system is typically built into the firmware and is highly tailored to the system; this includes smartphones and tablet computers running Android and other Linux derivatives, TiVo and similar DVR devices, network routers, facility automation controls, televisions, video game consoles and smartwatches. This updated and expanded second edition of Book provides a user-friendly introduction to the subject, Taking a clear structural framework, it guides the reader through the subject's core elements.
