The SELinux Notebook

Introduction

This Notebook should help with explaining:

  1. SELinux and its purpose in life.
  2. The LSM / SELinux architecture, its supporting services and how they are implemented within GNU / Linux.
  3. SELinux Networking, Virtual Machine, X-Windows, PostgreSQL and Apache/SELinux-Plus SELinux-aware capabilities.
  4. The core SELinux kernel policy language and how basic policy modules can be constructed for instructional purposes.
  5. An introduction to the new Common Intermediate Language (CIL) implementation.
  6. The core SELinux policy management tools with examples of usage.
  7. The Reference Policy architecture, its supporting services and how it is implemented.
  8. The integration of SELinux within Android.

Notebook Overview

This volume has the following major sections:

SELinux Overview - Gives a description of SELinux and its major components to provide Mandatory Access Control services for GNU / Linux. Hopefully it will show how all the SELinux components link together and how SELinux-aware applications / object manager have been implemented (such as Networking, X-Windows, PostgreSQL and virtual machines).

SELinux Configuration Files - Describes all known SELinux configuration files with samples. Also lists any specific SELinux commands or libselinux APIs used by them.

SELinux Policy Language - Gives a brief description of each policy language statement, with supporting examples taken from the Reference Policy source. Also an introduction to the new CIL language (Common Intermediate Language).

The Reference Policy - Describes the Reference Policy and its supporting macros.

Android - An overview of the SELinux services used to support Android.

Object Classes and Permissions - Describes the SELinux object classes and permissions.

Building HTML/PDF/EPUB Versions

The BUILD.md file has more information on building HTML, PDF and EPUB versions of the notebook as well as alternate ways to view the source markdown. Note that the EPUB build will optionally produce a version suitable for viewing on a Kindle that supports the "azw3" file format.
