security-dashboard（安全仪表板）

Security Dashboard Skill

Real-time security monitoring dashboard for OpenClaw and Linux server infrastructure.

Features

• OpenClaw Security: Gateway status, binding, authentication, sessions, version tracking
• Network Security: Tailscale status, public ports, firewall, active connections
• Public Exposure: Port binding analysis, dashboard security, exposure level assessment
• System Security: Updates, uptime, load, failed login attempts
• SSH & Access: Password auth status, fail2ban, banned IPs, active sessions
• Certificates & TLS: Caddy status, TLS configuration, WireGuard encryption
• Resource Security: CPU/memory/disk usage, config file permissions

Installation

1. Install the Skill

cd /root/clawd/skills/security-dashboard
sudo ./scripts/install.sh

This will:

• Ask user preference: Run as dedicated user (recommended) or root
• Create openclaw-dashboard user with limited sudo privileges (if non-root)
• Create systemd service with security hardening
• Configure localhost binding (127.0.0.1 only)
• Start the dashboard on port 18791
• Enable auto-start on boot

Security Note: Running as a dedicated user with limited sudo is recommended. The dashboard only needs sudo for security checks (fail2ban, firewall, systemctl status) - not full root access.

2. Access the Dashboard

Localhost only (secure by default):

Via SSH port forwarding:

ssh -L 18791:localhost:18791 root@YOUR_SERVER_IP

Then visit: http://localhost:18791

Usage

Start/Stop/Restart

sudo systemctl start security-dashboard
sudo systemctl stop security-dashboard
sudo systemctl restart security-dashboard

Check Status

sudo systemctl status security-dashboard

View Logs

sudo journalctl -u security-dashboard -f

API Endpoint

Get raw security metrics:

curl http://localhost:18791/api/security | jq

Security Hardening

The dashboard follows security best practices to minimize attack surface:

Dedicated User (Recommended)

The install script creates a openclaw-dashboard user with limited sudo privileges:

• ✅ No shell access (/bin/false)
• ✅ No home directory
• ✅ Only specific sudo commands allowed (fail2ban, firewall, systemctl status)
• ✅ Cannot execute arbitrary commands

Systemd Hardening

Service runs with security restrictions:

NoNewPrivileges=true      # Cannot escalate privileges
PrivateTmp=true          # Isolated tmp directory
ProtectSystem=strict     # Read-only filesystem except skill dir
ProtectHome=true         # No access to /home
ReadWritePaths=...       # Only skill directory is writable
Restart=on-failure       # Restart only on crashes (not always)

Network Binding

• Default: 127.0.0.1 (localhost only)
• Not accessible from network without SSH tunnel or VPN
• No public exposure risk

Running as Root (Not Recommended)

If you choose root during install:

• ⚠️ Full system access if compromised
• ⚠️ No privilege separation
• ⚠️ Only suitable for trusted, isolated environments

Use the dedicated user option for production deployments.

Configuration

Change Port

Edit /root/clawd/skills/security-dashboard/server.js:

const PORT = 18791; // Change this

Then restart:

sudo systemctl restart security-dashboard

Change Binding

Default: 127.0.0.1 (localhost only - secure) Alternative: 0.0.0.0 (all interfaces - only with Tailscale!)

Edit server.js line 445:

server.listen(PORT, '127.0.0.1', () => {
  // Change '127.0.0.1' to '0.0.0.0' if needed
});

⚠️ Security Warning: Only bind to 0.0.0.0 if behind Tailscale or firewall!

Customize Metrics

Add custom checks in server.js:

• getOpenClawMetrics() - OpenClaw-specific metrics
• getNetworkMetrics() - Network security
• getSystemMetrics() - System-level checks
• getPublicExposure() - Port/binding analysis

Dashboard Sections

🦞 OpenClaw Security

• Gateway running/stopped status
• Binding configuration (loopback/public)
• Auth token length and mode
• Active sessions + subagents
• Skills count
• Current version + update availability

🌐 Network Security

• Tailscale connection status + IP
• Public ports count
• Firewall status (UFW/firewalld)
• Active TCP connections

🌍 Public Exposure

• Exposure level (Excellent/Minimal/Warning/High)
• Public port details (service names)
• Kanban board binding
• Security dashboard binding
• OpenClaw gateway binding
• Tailscale active/inactive
• Security recommendations

🖥️ System Security

• Updates available
• Server uptime
• Load average
• Failed SSH logins (24h)
• Root processes count

🔑 SSH & Access Control

• SSH service status
• Password authentication (enabled/disabled)
• fail2ban status
• Banned IPs count
• Active SSH sessions

📜 Certificates & TLS

• Caddy status
• Public TLS enabled/disabled
• Tailscale WireGuard encryption

📊 Resource Security

• CPU usage percentage
• Memory usage percentage
• Disk usage percentage
• Config file permissions (should be 600)

Security Alerts

Dashboard generates real-time alerts:

Critical (Red):

• Weak gateway token (< 32 chars)
• SSH password authentication enabled
• Insecure config permissions (not 600)
• Firewall inactive (UFW/firewalld not running)
• fail2ban inactive (SSH brute-force protection disabled)

Warning (Yellow):

• Tailscale disconnected
• 20+ system updates available
• 10+ failed login attempts in 24h
• Disk > 80% full

Info (Blue):

• Gateway exposed without Tailscale
• Non-standard configurations

Integration Points

Morning Briefing

Add security status to morning report:

curl -s http://localhost:18791/api/security | jq '.status'

Heartbeat Checks

Monitor for critical alerts:

curl -s http://localhost:18791/api/security | \
  jq '.alerts[] | select(.level == "critical")'

Alerting Integration

Pipe alerts to notification systems:

./scripts/check-alerts.sh | xargs -I {} notify-send "Security Alert" "{}"

Architecture

Backend: Node.js HTTP server Frontend: Vanilla JavaScript (no frameworks) Port: 18791 (configurable) Binding: 127.0.0.1 (localhost only) Service: systemd unit

Files:

• server.js - Main backend (metrics collection + API)
• public/index.html - Dashboard UI
• lib/ - Shared utilities (if needed)

Dependencies

• Node.js (v18+)
• systemctl - Service management
• ss - Socket statistics
• ufw or firewalld - Firewall check
• tailscale - VPN status (optional)
• fail2ban - Ban tracking (optional)
• openclaw - Gateway monitoring

All dependencies are standard Linux utilities except OpenClaw.

Troubleshooting

Dashboard not loading

1. Check service status:

   sudo systemctl status security-dashboard

1. Check logs:

   sudo journalctl -u security-dashboard -n 50

1. Verify port is listening:

   ss -tlnp | grep 18791

1. Test API directly:

   curl http://localhost:18791/api/security

Gateway Status "Unknown"

• Verify OpenClaw gateway is running:

  pgrep -f openclaw-gateway

• Check OpenClaw config exists:

  cat ~/.openclaw/openclaw.json

Metrics showing "Unknown"

• Commands may require sudo permissions
• Check script execution permissions
• Verify paths exist (sessions, skills, etc.)

Uninstall

sudo systemctl stop security-dashboard
sudo systemctl disable security-dashboard
sudo rm /etc/systemd/system/security-dashboard.service
sudo systemctl daemon-reload

Then remove skill directory:

rm -rf /root/clawd/skills/security-dashboard
