How "secure" is your setup? (lemmy.dbzer0.com)

What setups/softwares do you use to secure your server?

All I do is run the process as user with no login shell.

The topic came to mind after reading this post Is Authelia enough without fail2ban or crowdsec?

I operate SSH, nginx, and uvicorn like this:

SSH

pubkey auth only
not on default port
AllowUsers var in sshd.conf is set

nginx

runs as its own user
serves static files or forwards to uvicorn
rate limits are set
returns 444 on requests that aren't in sitemap.xml (nonsense and probing)

uvicorn

runs as its own user

and a firewall runs on top of everything in a hardened kernel. I'm self taught, so I could be missing something obvious and this setup has been reliable for me for a few years.

Do you have any sort of access limiting, either by whitelist (e.g. Tailscale), or blacklist (e.g. Crowd-Sec)?

[–] lntl@lemmy.ml 3 points 3 days ago* (last edited 3 days ago)

Nope, I'm accessible on the WAN and the webserver is intentionally public facing.

Edit: AllowUsers in sshd.conf is my access control
