What to read about Linux administration for the user?

Question

linux

I have been wanting to expand my knowledge in this area for a long time, and with the latest events, this is becoming even more relevant. Tell me what to read in this direction? The main issues are separation of rights, samba, network security, firewall settings. I don’t pursue great knowledge, since the main direction is different, but I want to get at least basic skills in these matters, in relation to a home computer. But if you still read a lot, I'll manage somehow))
