SELinux by Example: Using Security Enhanced Linux

In this chapter

An SELinux system looks and feels like any other Linux system in many ways. Indeed, Red Hat Enterprise Linux (RHEL) is an SELinux system whether you know it or not. However, with the enhanced security, "something" can break or not work for more reasons than before. Fixing problems may require additional administration procedures, and normal operations may now require additional steps. In this chapter, we discuss the way in which SELinux affects a Linux administrator and how to accomplish the most common important tasks.
