Fix Recommendation

Configure OL 9 to verify correct operation of security functions.

Edit the file "/etc/selinux/config" and add or modify the following line:

SELINUX=enforcing

A reboot is required for the changes to take effect.

Check Contents

Verify that OL 9 enforces the correct operation of security functions through the use of SELinux with the following command:

$ getenforce
Enforcing

If SELINUX is not set to "Enforcing", this is a finding.

Verify that SELinux is configured to be enforcing at boot.

$ grep "SELINUX=" /etc/selinux/config
# SELINUX= can take one of these three values:
# NOTE: In earlier Fedora kernel builds, SELINUX=disabled would also
SELINUX=enforcing

If SELINUX line is missing, commented out, or not set to "enforcing", this is a finding.
