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.

GeoIP blocking

You mention a firewall, but for any open ports still restrict the source IPs to limited ranges not "all".

Personally, at my home's edge firewall I have pfSense with pfBlocker and that uses a GeoIP database, so I can just pick the countries I want to allow in... you want to block as early as possible (ie at the VPS?), so you might have to look at options

If your family are in the same region, then it should be relatively easy to limit to a few ranges on the VPS

Here's a quick search result: https://lite.ip2location.com/ip-address-ranges-by-country

Really good point. I can definitely restrict to one country and anyone using their own VPNs/TOR/whatever will be sophisticated enough to understand why its restricted and how to keep their access.

Just came back to say the same thing, I use this for geo ip blocking and it’s so well featured it’s insane. Any VPS, just make sure to clear local IPs (incl. docker range if using docker - though it’s been improving so much it may handle that automatically now)
