I put up a vps with nginx and the logs show dodgy requests within minutes, how do you guys deal with these?

Edit: Thanks for the tips everyone!

  • Turn off password login for SSH and only allow SSH keys
  • Cloudflare tunnel
  • Configure nginx to resolve the real IPs since it will now show a bunch of Cloudflare IPs. See discussion.
  • Use Fail2ban or Crowdsec for additional security for anything that gets past Cloudflare and also monitor SSH logs.
  • Only incoming port that needs to be open now is SSH. If your provider has a web UI console for your VPS you can also close the SSH port, but that's a bit overkill.
