Overview of this book

Do you have the crucial job of protecting your private and company systems from malicious attacks and undefined application behavior? Are you looking to secure your Linux systems with improved access controls? Look no further, intrepid administrator! This book will show you how to enhance your system’s secure state across Linux distributions, helping you keep application vulnerabilities at bay. This book covers the core SELinux concepts and shows you how to leverage SELinux to improve the protection measures of a Linux system. You will learn the SELinux fundamentals and all of SELinux’s configuration handles including conditional policies, constraints, policy types, and audit capabilities. These topics are paired with genuine examples of situations and issues you may come across as an administrator. In addition, you will learn how to further harden the virtualization offering of both libvirt (sVirt) and Docker through SELinux. By the end of the book you will know how SELinux works and how you can tune it to meet your needs.

Preface

Chapter 6. sVirt and Docker Support

More and more system tools have built-in support for SELinux or use SELinux's features to further harden their own service offerings. When we look at virtualization, two open source projects will definitely come to mind: libvirt and Docker. While the former supports full virtualization, the latter focuses on container management. In this chapter, administrators will:

  • Learn how SELinux can help reduce the risks of virtualization

  • Understand how SELinux's policy is tuned to support these services

  • Deal with the secure virtualization option supported through the libvirt API

We'll end the chapter with a section on Securing Docker containers with SELinux.
