(Fedora-42; stand-alone workstation)

This is a totally new Fedora install on a stand-alone workstation, done today.  It is not a part of a LAN or WAN or any other home or office network.
It is not dual-boot.
I do need for Firefox, Thunderbird, and dnf to be able to interact with the "outside world" appropriately.  I do occasionally need to be able to download or upload things. Beyond those (and maybe other appropriate things that don't at the moment come to mind), I do not want anyone or anything to be able to get into this workstation.  For example, no "ssh", "scp", "rlogin".

I gather from the Fedora docs that I should use firewalld or firewalld- config.  I have both.  But Fedora docs does not give me enough detail.  I am not an IT professional.  What specifically should I do to keep unwanted people and things out?

That's the default Workstation configuration.  ssh isn't enabled unless you turn it on in settings.

I'm curious how firefox will be able to interact with the outside world if it's not part of a network though.  :-)

Thank-you, Samuel.

My apologies if I did not word my initial post well.  The workstation is connected to a modem via an ethernet cable.  The modem connects to the internet service provider (comcast) via common co-ax(?) cable.

securing this workstation: part 2.

The login screen has 2 named users:
1. a user that Anaconda had me create.
2. "Super User", which I did ***not*** create.
Then there's something else below those that I can use to log in as root.
What is "Super User"; where did that come from?
