Chapter 6. Confining Users

A number of confined SELinux users are available in Red Hat Enterprise Linux 6. Each Linux user is mapped to an SELinux user via SELinux policy, allowing Linux users to inherit the restrictions placed on SELinux users, for example (depending on the user), not being able to: run the X Window System; use networking; run setuid applications (unless SELinux policy permits it); or run the su and sudo commands. This helps protect the system from the user. Refer to Section 4.3, “Confined and Unconfined Users” for further information about confined users.
