The /etc/selinux/ Directory

The /etc/selinux/ directory is the primary location for all policy files as well as the main configuration file.
The following example shows sample contents of the /etc/selinux/ directory:
-rw-r--r--  1 root root  448 Sep 22 17:34 config
drwxr-xr-x  5 root root 4096 Sep 22 17:27 strict
drwxr-xr-x  5 root root 4096 Sep 22 17:28 targeted
The two subdirectories, strict/ and targeted/, are the specific directories where the policy files of the same name (i.e., strict and targeted) are contained.
For more information on SELinux policy and policy configuration, refer to the rhel-selg.
