Hi, I know this topic has been talked about 70 thousand times but I’m still not sure.
I have home server on an intel NUC behind the ISP router. On it I have the standard arr apps, jellyfin, pi-hole etc etc. I would like to access them through a domain rather than an IP. So I set them up in docker, behind traefik, behind authelia and behind cloudflare. I am the only one that uses it.
Now, I’m worried about the security of it all. I’ve been searching here and there and I’ve read about cf tunnels, wireguard server, vps, vlan, OPNsense etc etc. I still don’t know what would be the most secure. Should I just stay with what I have?
EDIT: I’m not behind CGNAT
Make your services password protected and have some software like fail2ban that blocks people from brute-forcing passwords.
Keep your software up to date.
They are password protected. Plus, behind 2FA authelia. Plus Crowdsec (which originally made me make this post, cos I can see http probing etc on it)
Alright. I wouldn’t worry too much, then. If you set it up correctly and you keep it up to date so there aren’t any security vulnerabilities, you should be okay.
Of course there are arbitrary, more strict approaches. You could do monitoring. Or restrict the IP addresses the server answers to. Or put everything behind a VPN and not have it exposed. But I also have my NAS and a few internet services like Nextcloud and it’s been fine, similar to this, for years.
Thanks, I’m a bit calmer now :)
Same, have had a few select services exposed to the internet, behind very, very complex passwords or keys, with fail2ban etc. never had an incidence.
