Synopsis

A step-by-step guide to learn how to set up security on Linux servers by taking SELinux policies into your own hands. Linux 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.

A propos du livre

Présentation de l'éditeur

With a command of SELinux you can enjoy watertight security on your Linux servers. This guide shows you how through examples taken from real-life situations, giving you a good grounding in all the available features.

Overview

• Use SELinux to further control network communications
• Enhance your system's security through SELinux access controls
• Set up SELinux roles, users and their sensitivity levels

In Detail

NSA Security-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 book

• Enable and disable features selectively or even enforce them to a granular level
• Interpret SELinux logging to make security-conscious decisions
• Assign new contexts and sensitivity labels to files and other resources
• Work with mod_selinux to secure web applications
• Use tools like sudo, runcon, and newrole to switch roles and run privileged commands in a safe environment
• Use iptables to assign labels to network packets
• Configure IPSec and NetLabel to transport SELinux contexts over the wire
• Build your own SELinux policies using reference policy interfaces

Approach

A step-by-step guide to learn how to set up security on Linux servers by taking SELinux policies into your own hands.

Biographie de l'auteur

Sven Vermeulen

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 since then. In 2003, he joined the ranks of the Gentoo Linux project as a documentation developer and has crossed several roles after that, including Gentoo Foundation's trustee, council member, project leads for documentation, and (his current role) project lead for Gentoo Hardened's SELinux integration.

In this time frame, he has gained expertise in several technologies, ranging from operating system level knowledge to application servers as he used his interest in security to guide his projects further: security guides using SCAP languages, mandatory access controls through SELinux, authentication with PAM, (application) firewalling, and more.

On SELinux, he has contributed several policies to the reference policy project and participates actively in policy development and user space development projects.

Sven is an IT infrastructure architect working at a European financial institution. Secured implementation of infrastructure (and the surrounding architectural integration) is of course an important part of this. Prior to this, he graduated with an MSc in Computer Engineering at the University of Ghent and then worked as a web application infrastructure engineer with IBM WebSphere AS.

Sven is the main author of Gentoo's Handbook which covers the installation and configuration of Gentoo Linux on several architectures. He also authored the Linux Sea online publication, which is a gentle introduction to Linux for novice system administrators.
