🔧 ClawGuard Security Checker (CG-SC) v3

Enterprise-grade security configuration analyzer and runtime integrity verifier for OpenClaw environments. Provides comprehensive security posture assessment with advanced configuration analysis, permission modeling, and one-click hardening recommendations.

When to Use

Activate ClawGuard Checker when:

• A user asks to check the security status of the OpenClaw instance
• Periodic security review is needed
• After configuration changes
• User asks for "security check", "hardening", or "how to secure"

How to Execute

Follow these steps when performing a security check:

Step 1: Check Configuration File

• Find and read ~/.openclaw/openclaw.json
• Verify these security settings:
  • gateway.bind should be "localhost" (not "0.0.0.0" or "lan")
  • gateway.tls.enabled should be true
  • gateway.auth.deviceAuth should be true
  • tools.profile should be "restricted" (not "full")
  • tools.fs.workspaceOnly should be true

Step 2: Check for Exposed Credentials

Search for exposed secrets in:

• Config files (API keys, tokens, passwords)
• Environment files (.env)
• Log files

Step 3: Check File Permissions

Verify these permissions:

• ~/.openclaw/openclaw.json should be 600 (owner read/write only)
• ~/.openclaw/ directory should be 700
• SSH keys should be 600
• Not running as root user

Step 4: Check Network Settings

• Gateway port should not be exposed to 0.0.0.0
• Trusted proxies should be limited
• Rate limiting should be enabled

Step 5: Generate Hardening Recommendations (v3)

Based on findings, generate specific recommendations:

• CRITICAL issues: Generate immediate fix
• HIGH issues: Generate configuration changes
• MEDIUM issues: Suggest improvements

Step 6: Output Result

Calculate security score and output:

• Score: 0-100
• Grade: A+ to F
• List of issues found
• Hardening recommendations (v3)

Purpose

ClawGuard Security Checker is the second line of defense, providing continuous security posture monitoring for OpenClaw instances. It verifies:

• Configuration Security: Comprehensive analysis of OpenClaw configuration files
• Runtime Integrity: Cryptographic verification of system files and runtime components
• Permission Modeling: Advanced permission analysis and least-privilege enforcement
• Network Security: Multi-layered network policy validation
• Log Forensics: AI-powered anomaly detection in audit logs
• Compliance: Security benchmark compliance checking
• Hardening (v3): One-click security configuration generation

Phase 1: Configuration Analysis

Configuration File Schema

The analyzer examines openclaw.json for security-relevant settings:

{
  "gateway": {
    "bind": "localhost",
    "port": 8080,

      "certPath": "/path/to/cert.pem",
      "keyPath": "/path/to/key.pem"
    },
    "auth": {
      "deviceAuth": true,
      "tokenExpiry": 3600
    },
    "cors": {
      "allowedOrigins": ["https://example.com"]
    }
  },
  "tools": {
    "profile": "restricted",
    "fs": {
      "workspaceOnly": true,
      "allowedPaths": ["/workspace/*"]
    },
    "network": {
      "egressRestrictions": true,
      "allowedDomains": ["api.github.com", "api.openai.com"]

    rule: (config) => config.network?.allowedDomains?.length > 0,
    severity: 'HIGH',
    points: -10,
    message: 'No egress domain whitelist configured',
    fix: { network: { allowedDomains: ['api.github.com', 'api.openai.com'] } }
  },
  {
    check: 'trusted_proxies',
    rule: (config) => config.trustedProxies?.length \x3C= 2,
    severity: 'MEDIUM',
    points: -5,
    message: 'Limited proxy trust configured'
  }
];

Phase 5: Hardening Recommendations (v3 核心功能)

One-Click Hardening

Based on detected issues, generate hardened configuration:

const HARDEENING_RULES = {
  // Gateway Hardening
  gateway: {
    bind: { value: '127.0.0.1', reason: 'Only local access' },
    tls: { value: { enabled: true }, reason: 'Encrypted communication' },
    auth: { value: { mode: 'token', token: '\x3CGENERATE>' }, reason: 'Authentication required' },
    rateLimit: { value: { enabled: true, max: 100, windowMs: 60000 }, reason: 'DDoS protection' },
    cors: { value: { enabled: true, origin: [], credentials: true }, reason: 'Controlled access' }
  },

  // Tools Hardening
  tools: {
    exec: {
      security: { value: 'allowlist', reason: 'Controlled execution' },
      allowlist: { value: ['ls', 'cat', 'grep', 'find', 'echo', 'pwd'], reason: 'Minimal command set' }
    },
    fs: {
      workspaceOnly: { value: true, reason: 'File system isolation' }
    }
  },

  // Sandbox Hardening
  sandbox: {
    enabled: { value: true, reason: 'Runtime isolation' },
    allowedPaths: { value: ['/tmp', '~/workspace'], reason: 'Controlled file access' },
    deniedPaths: { value: ['/home', '/root', '/etc', '/var'], reason: 'Protect system files' },
    maxMemory: { value: 512, reason: 'Resource limit' },
    timeout: { value: 60000, reason: 'Execution timeout' }
  }
};

Hardened Config Example

{
  "gateway": {
    "bind": "127.0.0.1",
    "auth": {
      "mode": "token",
      "token": "\x3CGENERATE: crypto.randomBytes(32).toString('hex')>"
    },
    "tls": {
      "enabled": true
    },
    "rateLimit": {
      "enabled": true,
      "max": 100,
      "windowMs": 60000
    }
  },
  "tools": {
    "exec": {
      "security": "allowlist",
      "allowlist": ["ls", "cat", "grep", "find", "echo", "pwd"]
    },
    "fs": {
      "workspaceOnly": true
    }
  },
  "sandbox": {
    "enabled": true,
    "allowedPaths": ["/tmp", "~/workspace"],
    "deniedPaths": ["/home", "/root", "/etc", "/var"],
    "maxMemory": 512,
    "timeout": 60000
  },
  "logging": {
    "enabled": true,
    "level": "info",
    "auditLog": true
  }
}

Security Scoring

Scoring Formula

SECURITY_SCORE = 100 - CONFIG_PENALTY - CREDENTIAL_PENALTY - PERMISSION_PENALTY - NETWORK_PENALTY

Where:
- CONFIG_PENALTY = CRITICAL*20 + HIGH*15 + MEDIUM*5
- CREDENTIAL_PENALTY = CRITICAL*25 + HIGH*15 + MEDIUM*5
- PERMISSION_PENALTY = CRITICAL*25 + HIGH*15 + MEDIUM*5
- NETWORK_PENALTY = CRITICAL*20 + HIGH*15 + MEDIUM*5
