Security Enhanced Linux (SELinux) brings additional security measures to your Linux system to further protect its resources.
In this chapter, we will cover:
Why SELinux uses labels to identify resources
How SELinux differs from traditional Linux access controls by enforcing security rules
How the access control rules enforced by SELinux are provided through policy files
In the end, we will cover an overview of the differences between SELinux implementations across Linux distributions.
