Purpose: How to accomplish specific tasks with SELinux in the desktop environment. This requires a major expansion of the content beyond the SELinux FAQ which will be amalgamated into this guide in use case scenarios.
A user who finishes reading this guide should be able to:
- Understand how the Linux kernel, policy, and user tools work together to implement SELinux in Fedora
- Understand the differences and interactions between legacy UNIX access controls and SELinux
- Determine, set, and understand the operational mode of SELinux in a Fedora system
- Determine, set, and understand object and file labels
- Understand how to perform an automatic relabeling of a file system
Audience: Individuals who are unfamiliar with SELinux and who need to learn how to function in an environment with SELinux enabled.
Approach: This document explains basic principles by explaining one principle at a time. The document assumes some familiarity with Linux/UNIX-specific terminology or concepts. Functionality is also compared, where appropriate, to what the reader may know from other OSes, particularly Microsoft Windows.
Assumptions: The reader has a standard Desktop class installation of Fedora with, including a user account with the default settings. The reader does have access to the root password. (We changed this "non-root access" assumption so that we can include more coverage of regular software updates and the installation of alternate packages and desktops.)
