## Quick Start

### 1. Installation

```bash
cd /root/Projects/watches

# Install dependencies (if not already installed)
npm install

# Verify security packages
npm list | grep -E "(helmet|rate-limit|validator|jwt|bcrypt)"
```

### 2. Environment Configuration

Create `.env` file with secure values:

```bash
# Generate secure JWT secret
JWT_SECRET=$(openssl rand -base64 48)

# Generate secure admin password hash
ADMIN_PASSWORD="YourSecurePassword123!@#"
ADMIN_PASSWORD_HASH=$(node -e "const bcrypt = require('bcryptjs'); console.log(bcrypt.hashSync('$ADMIN_PASSWORD', 10));")

# Create .env file
cat > .env << EOF
NODE_ENV=production
PORT=7600
HOST=0.0.0.0

# Security
JWT_SECRET=$JWT_SECRET
ADMIN_USERNAME=admin
ADMIN_PASSWORD_HASH=$ADMIN_PASSWORD_HASH

# reCAPTCHA (optional - get from https://www.google.com/recaptcha/admin)
RECAPTCHA_ENABLED=false
RECAPTCHA_SECRET_KEY=
RECAPTCHA_SITE_KEY=
RECAPTCHA_MIN_SCORE=0.5

# CORS Allowed Origins
ALLOWED_ORIGINS=http://45.61.58.125:7600,https://45.61.58.125:7600

# API Keys (comma-separated)
VALID_API_KEYS=

# Rate Limiting
API_RATE_LIMIT=100
API_RATE_WINDOW=15

# Logging
LOG_LEVEL=info
EOF

chmod 600 .env
```

### 3. Start Enterprise Security Server

```bash
# Using PM2 (recommended)
pm2 stop omega-watches
pm2 start server-enterprise-security.js --name omega-watches-secure

# Or using Node directly
node server-enterprise-security.js
```

### 4. Verify Security

```bash
# Check server status
curl http://localhost:7600/api/health

# Check security status
curl http://localhost:7600/api/security/status

# Test security headers
curl -I http://localhost:7600/api/health
```

---

## Configuration

### Rate Limiting

```javascript
// Current configuration (in server-enterprise-security.js)
{
  apiLimiter: 100 requests / 15 minutes,
  authLimiter: 5 attempts / 15 minutes,
  readLimiter: 200 requests / 15 minutes,
  writeLimiter: 20 requests / 15 minutes
}
```

**Customization:**
Edit `middleware/security.js` and modify rate limit values.

### CAPTCHA Setup

#### Option 1: reCAPTCHA v3 (Recommended)

1. Get reCAPTCHA keys from https://www.google.com/recaptcha/admin
2. Add to `.env`:
   ```
   RECAPTCHA_ENABLED=true
   RECAPTCHA_SECRET_KEY=your_secret_key
   RECAPTCHA_SITE_KEY=your_site_key
   RECAPTCHA_MIN_SCORE=0.5
   ```
3. Add to frontend:
   ```html
   <script src="https://www.google.com/recaptcha/api.js?render=YOUR_SITE_KEY"></script>
   ```

#### Option 2: Simple Math CAPTCHA (Fallback)

Already implemented! No configuration needed.

```javascript
// Get CAPTCHA
GET /api/captcha/generate
Response: { id: "...", question: "What is 7 + 3?", expiresAt: ... }

// Submit with answer
POST /api/admin/login
{
  "username": "admin",
  "password": "password",
  "captchaId": "...",
  "captchaAnswer": "10"
}
```

### Intrusion Detection System

```javascript
// Thresholds (in security/intrusion-detection.js)
{
  maxFailedAuth: 5,              // Auto-block after 5 failed logins
  maxRequestsPerMinute: 60,      // Suspicious if exceeds
  maxValidationErrors: 10,       // Suspicious if exceeds
  suspiciousScore: 50            // Block if score >= 50
}
```

**Auto-blocking:**
- Score >= 80: Instant block (1 hour)
- Score >= 50: Alert only
- Failed auth >= 5: Block (15 minutes)
- Validation errors >= 10: High alert

---

## Security Features Reference

### 1. Content Security Policy (CSP)

```http
Content-Security-Policy:
  default-src 'self';
  script-src 'self' 'unsafe-inline' https://cdn.jsdelivr.net;
  style-src 'self' 'unsafe-inline' https://fonts.googleapis.com;
  font-src 'self' https://fonts.gstatic.com data:;
  img-src 'self' data: https: blob:;
  connect-src 'self' ws://45.61.58.125:7600 wss://45.61.58.125:7600;
  frame-src 'none';
  object-src 'none';
```

**Protection Against:**
- XSS attacks
- Clickjacking
- Code injection
- Unauthorized resource loading

### 2. HTTP Strict Transport Security (HSTS)

```http
Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
```

**Features:**
- Forces HTTPS for 1 year
- Includes all subdomains
- HSTS preload ready

**Submit to HSTS Preload:** https://hstspreload.org/

### 3. JWT Authentication

```bash
# Login
POST /api/admin/login
{
  "username": "admin",
  "password": "YourSecurePassword"
}

Response:
{
  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
  "expiresIn": "24h"
}

# Use token
GET /api/admin/security-logs
Headers: {
  "Authorization": "Bearer YOUR_TOKEN_HERE"
}
```

**Token Details:**
- Algorithm: HS256
- Expiry: 24 hours
- Payload: { userId, role }

### 4. SQL Injection Prevention

**Features:**
- Pattern-based detection (50+ patterns)
- Parameterized query enforcement
- Keyword blocking
- Auto-sanitization
- Whitelist validation

**Protected Patterns:**
- UNION SELECT attacks
- Stacked queries
- Boolean-based injection
- Time-based injection
- Comment injection
- Encoding bypass attempts

**Example:**

```javascript
// Dangerous input
const input = "'; DROP TABLE watches; --";

// Automatically sanitized to
const sanitized = " DROP TABLE watches  ";

// Then validated (FAIL - contains DROP keyword)
```

### 5. Intrusion Detection System (IDS)

**Detection Methods:**
- SQL injection patterns
- XSS patterns
- Path traversal
- Command injection
- Directory enumeration
- Suspicious user agents
- Request rate anomalies
- Behavioral analysis

**Responses:**
- Score 0-30: Allow
- Score 30-50: Log + Monitor
- Score 50-80: Alert
- Score 80+: Auto-block

**Forensic Data:**
```bash
POST /api/admin/export-forensics
Authorization: Bearer <token>

# Creates: /logs/forensic-{timestamp}.json
{
  "timestamp": "...",
  "blockedIPs": [...],
  "suspiciousActivity": [...],
  "securityLogs": [...]
}
```

done
wait

# Expected: First 100 succeed, rest return 429
```

### 2. SQL Injection Test

```bash
# Attempt SQL injection
curl "http://localhost:7600/api/search?q='; DROP TABLE watches; --"

# Expected: Input sanitized, no SQL executed
# Response: Sanitized query or validation error
```

### 3. XSS Test

```bash
# Attempt XSS attack
curl -X POST http://localhost:7600/api/watchlist \

  -d '{
    "userId": "<script>alert(1)</script>",
    "watchId": "test",
    "action": "add"
  }'

# Expected: Script tags removed, clean data stored
```

### 4. Brute Force Test

```bash
# Attempt multiple failed logins
for i in {1..10}; do
  curl -X POST http://localhost:7600/api/admin/login \
    -H "Content-Type: application/json" \
    -d '{"username":"admin","password":"wrong"}'

  -H "Authorization: Bearer invalid_token"

# Expected: 403 Forbidden
```

### 6. Security Headers Test

```bash
# Check all security headers
curl -I http://localhost:7600/api/health

```

### Setup Alerts (Optional)

**Email Alerts:**
```javascript
// Add to security/intrusion-detection.js
ids.onAlert(async (alert) => {
  if (alert.severity === 'CRITICAL') {
    // Send email
    await sendEmail({
      to: process.env.SECURITY_EMAIL,
      subject: `CRITICAL: ${alert.message}`,
      body: JSON.stringify(alert, null, 2)
    });
  }
});
```

**Slack Alerts:**
```javascript
ids.onAlert(async (alert) => {
  if (['CRITICAL', 'HIGH'].includes(alert.severity)) {
    await fetch(process.env.SLACK_WEBHOOK_URL, {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({
        text: `🚨 Security Alert: ${alert.message}`,
        attachments: [{
          color: alert.severity === 'CRITICAL' ? 'danger' : 'warning',
          fields: [
            { title: 'Severity', value: alert.severity, short: true },
