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.

During this time, Sven gained expertise in several technologies, ranging from OS-level knowledge to application servers. He used his interest in security to guide his projects further in the areas of security guides using SCAP languages, mandatory access controls through SELinux, authentication with PAM, (application) firewalling, and more.

In his daily job, Sven is an IT architect in a European financial institution as well as a self-employed solution engineer and consultant. The secure implementation of infrastructures (and the surrounding architectural integration) is, of course, an important part of this. Prior to this, he graduated with an MSc in computer engineering from Ghent University and MSc in ICT enterprise architecture from http://inno.com/, and he worked as a web application infrastructure engineer.
