Are there good places to read more about this?

If you just want to maintain or operate what's already there on a RHEL (clone): https://docs.redhat.com/en/documentation/red_hat_enterprise_...

If you want to dive deeper: "SELinux System Administration" by Sven Vermeulen.

A book published by Packt? Really? Honest question, it’s just that so far I haven’t noticed them having much of a quality filter or an editing team.
