## 3. Security Posture

### 3.1 Application Security
- **User registration:** Disabled (admin-only account creation)
- **Public browsing:** Disabled (requires sign-in to view)
- **Gravatar:** Disabled (no external avatar service calls)
- **Local mode:** Enabled (all assets served locally, no CDN)

- **Hidden email domain:** noreply.git.firefrostgaming.com

### 3.2 Network Security
- **Internal service binding:** Gitea bound to 127.0.0.1:3000 only (not externally accessible)
- **Reverse proxy isolation:** All external access via Nginx on dedicated IP
- **IP-specific firewall rules:** UFW rules target 74.63.218.202 only
- **Primary gateway protection:** 63.143.34.217 unchanged, zero new services

### 3.3 File Permissions
- **Configuration directory:** /etc/gitea (750, root:gitea)
- **Configuration file:** /etc/gitea/app.ini (640, gitea:gitea)
- **Application directories:** /var/lib/gitea/* (750, gitea:gitea)

```

**View logs:**
```bash
journalctl -u gitea -f
```

### 5.2 Nginx Management

**Test configuration:**
```bash
nginx -t
```

**Reload configuration:**
```bash
systemctl reload nginx
```

**Restart Nginx:**
```bash
systemctl restart nginx
```

### 5.3 SSL Certificate Renewal

## 6. Troubleshooting

### 6.1 Common Issues

**Issue:** Gitea not accessible via HTTPS
- **Check Nginx binding:** `ss -tlnp | grep 74.63.218.202`
- **Check Gitea service:** `systemctl status gitea`
- **Check firewall:** `ufw status | grep 74.63.218.202`
- **Check DNS:** `nslookup git.firefrostgaming.com`

**Issue:** 502 Bad Gateway
- **Cause:** Gitea service not running
- **Fix:** `systemctl start gitea`

**Issue:** Permission denied errors
- **Cause:** Incorrect file ownership or permissions
- **Fix:** `chown -R gitea:gitea /var/lib/gitea`

**Issue:** SSL certificate expired
- **Check expiration:** `certbot certificates`
- **Renew manually:** `certbot renew`

### 6.2 Port Binding Conflicts

**Check what's using a port:**
```bash
ss -tlnp | grep :PORT_NUMBER
```

**Check Nginx configuration:**
```bash
nginx -T | grep listen
```

## 7. Phase 0.5 Integration

### 7.1 Management Layer Position

**Gitea Role:** Source of truth for all Firefrost Gaming infrastructure configurations, scripts, and documentation.

**Integration Points:**
- **Uptime Kuma (Planned):** Will monitor Gitea health endpoint
- **BookStack (Planned):** Will reference Gitea repos in documentation
- **Netdata (Planned):** Will track Gitea resource usage
- **Vaultwarden (Planned):** Will store Gitea admin credentials
