PROD (192.168.100.2)

Status

ZURICH (zurich.inou.com / 82.22.36.202)

Firewall

  • ✅ UFW active with comprehensive rules:
    • 22, 80, 443, Tailscale, 25/143/587/465/993/4190 (mail)

SSH Hardening

  • ✅ PasswordAuthentication no
  • ✅ PermitRootLogin without-password
  • ✅ PubkeyAuthentication yes

fail2ban

  • ✅ Active (systemctl reports active)

Brute Force Activity

  • ⚠️ HIGH volume SSH brute force detected (20 failed attempts in ~15 min window today)
  • Example IPs: 80.94.92.164, 89.155.5.35, 20.185.243.158, 2.57.121.25, 57.128.214.238, 20.88.55.220, 101.47.163.102, 34.78.29.97, 139.59.157.104, 23.227.147.163
  • Usernames attempted: sol, opnsense, zookeeper, user, solana, listen, jfrog, polycom, rdp, serveradmin, borgbackup, blink, pound
  • Risk: LOW — password auth disabled, key-only auth, fail2ban active
  • This is expected/normal for a public VPS with port 22 open

Listening Ports

All expected:

  • 22 (SSH), 80/443 (Caddy), 25/143/587/465/993/995/110/4190 (Stalwart mail)
  • 2019 (Caddy admin — localhost), 2586 (ntfy — localhost), 8080/8880/8443 (localhost)

Docker Containers

  • uptime-kuma (louislam/uptime-kuma:1) — ✅ Up 3 days (healthy)
  • vaultwarden (vaultwarden/server) — ✅ Up 12 hours (healthy)

Users

  • nobody (65534), harry (1000 — /var/www/harryhaasjes, nologin), harry-web (1001 — nologin)
  • All expected service accounts

Root SSH Keys

  • 5 keys: claude@macbook, james@server, james@james, james@forge, johan@thinkpad-x1 — all expected

Login History

  • Last interactive: root from 47.197.93.62 (Johan's home IP) — Jan 27 — clean

Findings

Severity Finding
ℹ️ INFO High SSH brute force volume — mitigated (key-only + fail2ban)
ℹ️ INFO Port 3001 (Kuma) binding 0.0.0.0 — UFW blocks externally, but should bind localhost
ℹ️ INFO POP3 (110/995) listening but not in UFW rules — consider adding or disabling

Action Items

Priority Host Action
HIGH forge Install UFW or document why host firewall isn't needed
HIGH forge Install fail2ban
MEDIUM forge Review vsftpd — is FTP still needed? Disable if not
MEDIUM james-old Patch 53 pending updates, or decommission machine
MEDIUM james-old Enable UFW or document retirement status
MEDIUM caddy Install fail2ban (public-facing, should have brute-force protection)
MEDIUM staging Verify SSH hardening as root
MEDIUM prod Establish SSH access method for security scans
LOW zurich Change Kuma to bind localhost only (--listen 127.0.0.1)
LOW zurich Consider UFW rule for POP3 (995) if intentionally offered

No Intrusion Indicators Found

  • No unknown users on any accessible host
  • No rogue SSH keys
  • No suspicious processes
  • All login history from known IPs (LAN, Tailscale, Johan's home IP)
  • Zurich brute force — normal internet noise, all blocked
