Overview of this book

Fedora Linux is a free and open-source platform designed for hardware, clouds, and containers that enables software developers and community members to create custom solutions for their customers. This book is a comprehensive guide focusing on workstation configuration for the modern system administrator. The book begins by introducing you to the philosophy underlying the open-source movement, along with the unique attributes of the Fedora Project that set it apart from other Linux distributions. The chapters outline best practices and strategies for essential system administration tasks, including operating system installation, first-boot configuration, storage, and network setup. As you make progress, you’ll get to grips with the selection and usage of top applications and tools in the tech environment. The concluding chapters help you get a clear understanding of the basics of version control systems, enhanced Linux security, automation, virtualization, and containers, which are integral to modern system administration. By the end of this book, you’ll have gained the knowledge needed to optimize day-to-day tasks related to Linux-based system administration.

Summary

In this chapter, we gave an overview of the use of SELinux and differentiated the types of access control: discretionary and mandatory. SELinux, as a mandatory access control could help us to harden the security of our systems.

The use of SELinux is considered very complex, but we gave several examples that simplify how it works. SELinux is a labeling system.

We learned how to read the error logs with SELinux and found that there are only four scenarios where SELinux could fail, as looked at their solutions. The most common failures are with labels or when using custom configurations for services.

Also, policies could have errors and they should be reported to their developers.

In a less common case, we analyzed that the change of behavior of the policies could be due to an attack on our system.

In the next chapter, we will take an in-depth look at how to virtualize complete systems or take them to their smallest expression using containers.
