Ward off traditional security permissions and effectively secure your Linux systems with SELinux About This Book * Leverage SELinux to improve the secure state of your Linux system * A clear approach to adopting SELinux within your organization * Essential skills and techniques to help further your system administration career Who This Book Is For This book is for Linux administrators who want to control the secure state of their systems. It's packed with the latest information on SELinux operations and administrative procedures so you'll be able to further harden your system through mandatory access control (MAC) - a security strategy that has been shaping Linux security for years. What You Will Learn * Analyze SELinux events and selectively enable or disable SELinux enforcement * Manage Linux users and associate them with the right role and permission set * Secure network communications through SELinux access controls * Tune the full service flexibility by dynamically assigning resource labels * Handle SELinux access patterns enforced through the system * Query the SELinux policy in depth In Detail 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. Style and approach This book offers a complete overview of SELinux administration and how it integrates with other components on a Linux system. It covers the majority of SELinux features with a mix of real life scenarios, descriptions, and examples. This book contains everything an administrator needs to customize SELinux.

About the Author
Sven Vermeulen is a long-term contributor to various free software projects and the author of various online guides and resources. He got his first taste of free software in 1997 and never looked back. In 2003, he joined the ranks of the Gentoo Linux project as a documentation developer and has since worked in several roles, including Gentoo Foundation trustee, council member, project lead for various documentation initiatives, and (his current role) project lead for Gentoo Hardened SELinux integration and the system integrity project. 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. Within SELinux, Sven contributed several policies to the Reference Policy project, and he is an active participant in policy development and user space development projects. 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. Sven is the main author of the Gentoo Handbook, which covers the installation and configuration of Gentoo Linux on several architectures. He also authored the Linux Sea online publication, which is a basic introduction to Linux for novice system administrators, and SELinux System Administration and SELinux Cookbook for Packt Publishing.
