Securing a 'public' service for family (lemmy.world)

Edit: thanks for all your help and replies, this is a such a great community!

I would like to host a public service for some family, probably Peertube so we can share some videos. Invite only.

There's no way I'm going to get everyone onto a VPN, it's a non-starter though I would prefer it.

I am thinking to use a VPS with anubis and either crowdsec or fail2ban (or both?!) in front of Peertube. Will apply as much hardening as I can muster behind that: things in containers, systemd hardening, SELinux/Apparmor enabled/tuned, separate users for services, the usual. All ports shut except 80/443, firewall up.

Despite all this I expect it will get scanned and attacked as it will have to expose ports 80/443 to the world so for family it will just work.

Is there anything else I should consider for security? Is Peertube the weakest link in the chain? (a little concerned their min password length is 6 it seems and no 2fa). So long as I keep whole thing up-to-date is it as secure as anybody can manage these days (without resorting to VPN)?

Is it all too much hassle and I should look for a company that offers hosted Peertube so they can worry about it?

Thanks for any and all advice.

Thought process is: Peertube or some other service’s first job is the purpose for the service, so security likely won’t be as good as a service who’s first job is security.

Really good point. I see many selfhost instructions now that say 'we don't bother with HTTPS, just use a proxy to handle that' and maybe auth should go the same way as in there's good solutions that specialise in auth so it's not worth each project doing it themselves.

apps can’t deal with hitting Authentik 1st afaik

Another good consideration. There is an early Peertube app but I doubt my users will be using it, web access is fine for this. Perhaps apps for things like Lemmy/Mastodon/Peertube etc will need to work better with these auth frontends in future.
