This is a very nice introduction, for me, to SELinux. I have always ended up running my Linux system (basically a desktop) in "permissive" mode. The main reason is that I just wanted to get my work done and I kept getting "dings" from SELinux in Enfo...
urity-Enhanced Linux (SELinux) is a set of patches and added utilities to the Linux kernel to incorporate a strong, flexible, mandatory access control architecture into the major subsystems of the kernel. With its fine-grained yet flexible approach, it is no wonder Linux distributions are firing up SELinux as a default security measure.SELinux System Administration covers the majority of SELinux features through a mix of real-life scenarios, descriptions, and examples. Everything an administrator needs to further tune SELinux to suit their needs are present in this book.This book touches on various SELinux topics, guiding you through the configuration of SELinux contexts, definitions, and the assignment of SELinux roles, and finishes up with policy enhancements. All of SELinux's configuration handles, be they conditional policies, constraints, policy types, or audit capabilities, are covered in this book with genuine examples that administrators might come across.By the end, SELinux System Administration will have taught you how to configure your Linux system to be more secure, powered by a formidable mandatory access control.What you will learn from this bookEnable and disable features selectively or even enforce them to a granular levelInterpret SELinux logging to make security-conscious decisionsAssign new contexts and sensitivity labels to files and other resourcesWork with mod_selinux to secure web applicationsUse tools like sudo, runcon, and newrole to switch roles and run privileged commands in a safe environmentUse iptables to assign labels to network packetsConfigure IPSec and NetLabel to transport SELinux contexts over the wireBuild your own SELinux policies using reference policy interfacesApproachA step-by-step guide to learn how to set up security on Linux servers by taking SELinux policies into your own hands.Who this book is written forLinux administrators will enjoy the various SELinux features that this book covers and the approach used to guide the admin into understanding how SELinux works. The book assumes that you have basic knowledge in Linux administration, especially Linux permission and user management.
