SELINUX=enforcing

A reboot is required for the changes to take effect.

Check Contents

Verify RHEL 10 enforces 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 SELinux is configured to be enforcing at boot.

$ sudo grep "SELINUX=" /etc/selinux/config | grep -v '#'
SELINUX=enforcing

If an uncommented SELinux line is missing or not set to "enforcing", this is a finding.
