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.

I'd say you're good. I trust NPM's SSL forwarding so I'd say spin up Peertube and put NPM in front of it to manage your certs and such, and as long as both are up to date it'll be fine.

Realistically though, you could still use a VPN and have it be pretty easy for your family members IF you have access to their router console and IF said router supports network wide wireguard or openVPN connections. Having both networks tied in to eachother that way makes it so that nobody ever has to use a VPN client to connect, but still only devices from their network (or yours) will be able to connect.

Realistically this plan dies the moment someone takes their phone outside of the WiFi range. It's fine in theory, but fails miserably in non-techie real life.

"Where's the router you configured for me? Oh the Cox guy said I should just use their router for $9.99/mo so I donated it to Goodwill"

I had to look up NPM as in my head it's NodeJS Package Manager but TIL there's also Nginx Proxy Manager!

I like your VPN solution for a small group and actually tying it to their home network/router could make sense and further restrict attacks I have to deal with. However in my case I could be dealing with 30+ households of users and as others say I am bound to get people on mobiles complaining they can't access it. However noted for future projects.
