Is it considered bad practice to expose selfhosted services on public internet?
Is it considered bad practice to expose selfhosted services on public internet?
I see a lot of people here uses some form of remote access tool (VPN/Tailscale) to access their home network when not at home. I can’t really do this because my phone (iOS) can only activate one VPN profile at a time, and I often need this for other stuff.
So I chose to expose most web based services on the public internet, behind Authelia. But I don’t know how safe this is.
What I’m really unsure are things like Vaultwarden: while the web interface is protected by Authelia (even use 2FA), its API address needs to be bypassed for direct access, otherwise the mobile APP won’t work. It feels like this is negative everything I’ve done so far.

I have many of my services open to the internet, but behind authelia w/2fa and a reverse proxy. I haven't had a security issue yet, been running this way for a few years.
I think it's pretty safe as long as you keep them up to date. I run backups weekly and do updates at least once a month.
Using geoip restrictions will also help a lot because you can block most of the scanner bots by denying connections from outside your geographic region. These bots detect what services are open to the internet and then add them to databases like shodan. If a security flaw is found in one of those services, hackers will search those databases for servers with those services running and try to exploit them. If you aren't in those databases they can't easily find you before you are able to patch.
Very good point regarding geoip, thanks!
