When SELinux is disabled, SELinux policy is not loaded at all; it is not enforced and AVC messages are not logged. Therefore, all benefits of running SELinux listed in link:https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/using_selinux/getting-started-with-selinux_using-selinux#benefits-of-selinux_getting-started-with-selinux[Benefits of SELinux] are lost.
It is recommended to use permissive mode instead of permanently disabling SELinux. See xref:{context}-changing-to-permissive-mode[] for more information about permissive mode.
