Security & Compliance

Protect your business and customers with comprehensive security measures and ensure compliance with regulatory requirements.

🛡️ Security Overview

Security Principles

Torque follows industry-leading security practices to protect your business:

Data Protection

End-to-End Encryption: All data encrypted in transit and at rest
Secure Storage: Data stored in enterprise-grade secure facilities
Access Controls: Strict access controls and authentication
Regular Audits: Continuous security monitoring and testing

Infrastructure Security

Cloud Security: Built on secure cloud infrastructure
Network Security: Protected network with firewalls and monitoring
Physical Security: Secure data centers with 24/7 monitoring
Disaster Recovery: Comprehensive backup and recovery systems

🔑 API Security

API Key Management

Key Security Best Practices

Generate Strong Keys

# Use our secure key generation
# Keys are automatically generated with high entropy
# Format: torque_live_64characterstring

Secure Storage

# Environment Variables (Recommended)
export TORQUE_API_KEY="torque_live_your_api_key_here"
export TORQUE_BUSINESS_ID="business_your_business_id"

# Never commit to version control
# .gitignore should include:
.env
*.env
config/secrets.*

Key Rotation

Regular Rotation: Rotate keys every 90 days
Immediate Rotation: Rotate immediately if compromised
Gradual Rollout: Update applications gradually
Monitor Usage: Watch for unusual API activity

Key Permissions

Permission Levels

Read Only: View orders, analytics, customer data
Write Access: Create checkout links, manage orders
Admin Access: Full account management (use sparingly)

Access Control

// Example: Role-based API access
const apiPermissions = {
  'analytics': ['read'],
  'orders': ['read', 'write'],
  'webhooks': ['read', 'write'],
  'business': ['read', 'write', 'admin']
};

function checkPermission(resource, action) {
  const permissions = apiPermissions[resource] || [];
  return permissions.includes(action);
}

Request Security

HTTPS Enforcement

Always Use HTTPS: All API requests must use HTTPS
Certificate Validation: Verify SSL certificates
TLS 1.2+: Use modern TLS versions only

Request Validation

// Validate all input data
function validateCheckoutRequest(data) {
  const errors = [];
  
  // Required fields
  if (!data.businessId) errors.push('Business ID is required');
  if (!data.cart?.items?.length) errors.push('Cart must contain items');
  if (!data.customerData?.email) errors.push('Customer email is required');
  
  // Data format validation
  if (data.cart?.items) {
    data.cart.items.forEach((item, index) => {
      if (!item.productId) errors.push(`Item ${index}: Product ID required`);
      if (!item.quantity || item.quantity < 1) errors.push(`Item ${index}: Valid quantity required`);
      if (!item.price || item.price <= 0) errors.push(`Item ${index}: Valid price required`);
    });
  }
  
  return errors;
}

Rate Limiting

// Implement rate limiting
class RateLimiter {
  constructor(maxRequests = 1000, windowMs = 60000) {
    this.maxRequests = maxRequests;
    this.windowMs = windowMs;
    this.requests = new Map();
  }
  
  isAllowed(clientId) {
    const now = Date.now();
    const clientRequests = this.requests.get(clientId) || [];
    
    // Remove old requests
    const recentRequests = clientRequests.filter(time => now - time < this.windowMs);
    
    if (recentRequests.length >= this.maxRequests) {
      return false;
    }
    
    // Add current request
    recentRequests.push(now);
    this.requests.set(clientId, recentRequests);
    
    return true;
  }
}

🔗 Webhook Security

Webhook Verification

Signature Verification

HMAC SHA256 Verification

const crypto = require('crypto');

function verifyWebhookSignature(payload, signature, secret) {
  const expectedSignature = crypto
    .createHmac('sha256', secret)
    .update(JSON.stringify(payload))
    .digest('hex');
    
  return crypto.timingSafeEqual(
    Buffer.from(signature),
    Buffer.from(expectedSignature)
  );
}

// Usage in webhook handler
app.post('/webhooks/torque', (req, res) => {
  const signature = req.headers['x-torque-signature'];
  const payload = req.body;
  
  if (!verifyWebhookSignature(payload, signature, webhookSecret)) {
    return res.status(401).json({ error: 'Invalid signature' });
  }
  
  // Process webhook...
});

PHP Verification

<?php
function verifyWebhookSignature($payload, $signature, $secret) {
    $expectedSignature = hash_hmac('sha256', $payload, $secret);
    return hash_equals($expectedSignature, $signature);
}

// Usage
$signature = $_SERVER['HTTP_X_TORQUE_SIGNATURE'] ?? '';
$payload = file_get_contents('php://input');

if (!verifyWebhookSignature($payload, $signature, $webhookSecret)) {
    http_response_code(401);
    echo json_encode(['error' => 'Invalid signature']);
    exit;
}
?>

Python Verification

import hmac
import hashlib

def verify_webhook_signature(payload, signature, secret):
    expected_signature = hmac.new(
        secret.encode('utf-8'),
        payload.encode('utf-8'),
        hashlib.sha256
    ).hexdigest()
    
    return hmac.compare_digest(expected_signature, signature)

# Usage
@app.route('/webhooks/torque', methods=['POST'])
def webhook():
    signature = request.headers.get('X-Torque-Signature', '')
    payload = request.get_data(as_text=True)
    
    if not verify_webhook_signature(payload, signature, webhook_secret):
        return jsonify({'error': 'Invalid signature'}), 401
    
    # Process webhook...

Webhook Security Best Practices

Endpoint Security

HTTPS Only: Require HTTPS for all webhook endpoints
Authentication: Implement additional authentication if needed
IP Whitelisting: Restrict webhook sources if possible
Request Validation: Validate all webhook data

Error Handling

// Secure error handling
app.post('/webhooks/torque', async (req, res) => {
  try {
    // Verify signature first
    const signature = req.headers['x-torque-signature'];
    if (!verifyWebhookSignature(req.body, signature, webhookSecret)) {
      return res.status(401).json({ error: 'Unauthorized' });
    }
    
    // Process webhook
    await processWebhook(req.body);
    
    // Return success
    res.json({ success: true });
  } catch (error) {
    // Log error securely (don't expose sensitive data)
    console.error('Webhook processing error:', {
      timestamp: new Date().toISOString(),
      error: error.message,
      stack: error.stack
    });
    
    // Return generic error
    res.status(500).json({ error: 'Internal server error' });
  }
});

🔒 Data Security

Customer Data Protection

PII Handling

Data Minimization: Only collect necessary data
Encryption: Encrypt sensitive data at rest
Access Control: Limit access to customer data
Data Retention: Implement data retention policies

Secure Data Storage

// Example: Secure customer data handling
class CustomerDataManager {
  constructor(encryptionKey) {
    this.encryptionKey = encryptionKey;
  }
  
  encryptCustomerData(data) {
    // Encrypt sensitive fields
    const sensitiveFields = ['email', 'phone', 'address'];
    const encrypted = { ...data };
    
    sensitiveFields.forEach(field => {
      if (data[field]) {
        encrypted[field] = this.encrypt(data[field]);
      }
    });
    
    return encrypted;
  }
  
  decryptCustomerData(encryptedData) {
    // Decrypt sensitive fields
    const sensitiveFields = ['email', 'phone', 'address'];
    const decrypted = { ...encryptedData };
    
    sensitiveFields.forEach(field => {
      if (encryptedData[field]) {
        decrypted[field] = this.decrypt(encryptedData[field]);
      }
    });
    
    return decrypted;
  }
}

Payment Data Security

PCI Compliance

No Payment Storage: Never store payment card data
Tokenization: Use payment tokens when possible
Secure Transmission: Encrypt all payment data in transit
Access Logging: Log all access to payment information

Secure Payment Handling

// Example: Secure payment processing
class PaymentProcessor {
  constructor() {
    this.paymentGateway = new SecurePaymentGateway();
  }
  
  async processPayment(paymentData) {
    try {
      // Validate payment data
      this.validatePaymentData(paymentData);
      
      // Process payment securely
      const result = await this.paymentGateway.process(paymentData);
      
      // Log payment attempt (no sensitive data)
      this.logPaymentAttempt({
        amount: paymentData.amount,
        currency: paymentData.currency,
        status: result.status,
        timestamp: new Date().toISOString()
      });
      
      return result;
    } catch (error) {
      // Log error securely
      this.logPaymentError(error);
      throw error;
    }
  }
  
  validatePaymentData(data) {
    // Validate payment data without exposing sensitive information
    if (!data.amount || data.amount <= 0) {
      throw new Error('Invalid payment amount');
    }
    
    if (!data.currency) {
      throw new Error('Payment currency required');
    }
  }
}

📋 Compliance Requirements

Data Protection Principles

Lawful Processing: Process data only with legal basis
Purpose Limitation: Use data only for specified purposes
Data Minimization: Collect only necessary data
Accuracy: Keep data accurate and up-to-date
Storage Limitation: Don't keep data longer than needed
Integrity & Confidentiality: Protect data security

Customer Rights

Right to Access: Provide data access upon request
Right to Rectification: Allow data correction
Right to Erasure: Delete data upon request
Right to Portability: Export data in standard format
Right to Object: Allow processing objections
Right to Restriction: Limit data processing

Implementation

// Example: GDPR compliance implementation
class GDPRCompliance {
  constructor() {
    this.dataRetentionDays = 365; // 1 year retention
  }
  
  async handleDataRequest(customerId, requestType) {
    switch (requestType) {
      case 'access':
        return await this.provideDataAccess(customerId);
      case 'rectification':
        return await this.rectifyData(customerId);
      case 'erasure':
        return await this.eraseData(customerId);
      case 'portability':
        return await this.exportData(customerId);
      default:
        throw new Error('Invalid request type');
    }
  }
  
  async provideDataAccess(customerId) {
    const customerData = await this.getCustomerData(customerId);
    return {
      personalData: customerData.personal,
      processingPurposes: ['order_processing', 'customer_support'],
      dataRetention: this.dataRetentionDays,
      rights: ['access', 'rectification', 'erasure', 'portability']
    };
  }
  
  async eraseData(customerId) {
    // Implement data erasure
    await this.anonymizeCustomerData(customerId);
    await this.logDataErasure(customerId);
    return { success: true, message: 'Data erased successfully' };
  }
}

CCPA Compliance

California Privacy Rights

Right to Know: What personal information is collected
Right to Delete: Request data deletion
Right to Opt-Out: Opt out of data sales
Non-Discrimination: Equal service regardless of privacy choices

Implementation

// Example: CCPA compliance
class CCPACompliance {
  constructor() {
    this.privacyNotice = this.getPrivacyNotice();
  }
  
  async handleCCPARequest(customerId, requestType) {
    switch (requestType) {
      case 'know':
        return await this.provideDataInventory(customerId);
      case 'delete':
        return await this.deleteCustomerData(customerId);
      case 'opt-out':
        return await this.optOutOfDataSales(customerId);
      default:
        throw new Error('Invalid CCPA request type');
    }
  }
  
  async provideDataInventory(customerId) {
    const dataInventory = await this.getDataInventory(customerId);
    return {
      categories: dataInventory.categories,
      sources: dataInventory.sources,
      purposes: dataInventory.purposes,
      thirdParties: dataInventory.thirdParties
    };
  }
  
  getPrivacyNotice() {
    return {
      dataCollection: ['identifiers', 'commercial', 'internet'],
      dataUse: ['order_processing', 'customer_support', 'analytics'],
      dataSharing: ['payment_processors', 'shipping_partners'],
      optOutRights: ['data_sales', 'marketing_communications']
    };
  }
}

🚨 Security Incident Response

Incident Detection

Monitoring & Alerting

// Example: Security monitoring
class SecurityMonitor {
  constructor() {
    this.alerts = [];
    this.thresholds = {
      failedLogins: 5,
      apiErrors: 100,
      suspiciousActivity: 10
    };
  }
  
  monitorLoginAttempts(userId, success) {
    if (!success) {
      this.recordFailedLogin(userId);
      this.checkFailedLoginThreshold(userId);
    }
  }
  
  monitorAPIUsage(clientId, endpoint, responseCode) {
    if (responseCode >= 400) {
      this.recordAPIError(clientId, endpoint, responseCode);
      this.checkAPIErrorThreshold(clientId);
    }
  }
  
  checkFailedLoginThreshold(userId) {
    const failedAttempts = this.getFailedLoginCount(userId);
    if (failedAttempts >= this.thresholds.failedLogins) {
      this.triggerSecurityAlert('Multiple failed login attempts', { userId, attempts: failedAttempts });
      this.lockAccount(userId);
    }
  }
  
  triggerSecurityAlert(type, details) {
    const alert = {
      type,
      details,
      timestamp: new Date().toISOString(),
      severity: this.calculateSeverity(type, details)
    };
    
    this.alerts.push(alert);
    this.notifySecurityTeam(alert);
  }
}

Incident Response Plan

Response Steps

Detection: Identify security incident
Assessment: Evaluate incident severity

    name: 'PR Manager',
    responsibilities: ['Customer communication', 'External reporting']
  },
  legalAdvisor: {
    name: 'Legal Counsel',
    responsibilities: ['Compliance requirements', 'Legal obligations']
  }
};

🔐 Security Best Practices

Development Security

Code Security

Input Validation: Validate all user inputs
Output Encoding: Encode output to prevent XSS
SQL Injection Prevention: Use parameterized queries
Authentication: Implement strong authentication
Authorization: Enforce proper access controls

Security Testing

// Example: Security testing framework
class SecurityTester {
  constructor() {
    this.testResults = [];
  }
  
  async runSecurityTests() {
    await this.testAuthentication();
    await this.testAuthorization();
    await this.testInputValidation();
    await this.testOutputEncoding();
    await this.testSQLInjection();
    await this.testXSS();
    
    return this.generateSecurityReport();
  }
  
  async testAuthentication() {
    // Test authentication bypass attempts
    const testCases = [
      { username: '', password: 'test' },
      { username: 'admin', password: '' },
      { username: 'admin', password: 'admin' },
      { username: 'admin', password: 'password' }
    ];
    
    for (const testCase of testCases) {
      const result = await this.testLogin(testCase);
      this.testResults.push({
        test: 'Authentication',
        case: testCase,
        result: result.success ? 'FAIL' : 'PASS',
        details: result.message
      });
    }
  }
  
  generateSecurityReport() {
    const passed = this.testResults.filter(r => r.result === 'PASS').length;
    const total = this.testResults.length;
    const score = (passed / total) * 100;
    
    return {
      score,
      passed,
      total,
      results: this.testResults,
      recommendations: this.generateRecommendations()
    };
  }
}

Operational Security

Access Management

Principle of Least Privilege: Grant minimal necessary access
Role-Based Access Control: Assign permissions by role
Regular Access Reviews: Review access permissions regularly
Access Logging: Log all access attempts and actions

Security Monitoring

// Example: Security monitoring dashboard
class SecurityDashboard {
  constructor() {
    this.metrics = {
      failedLogins: 0,
      suspiciousActivities: 0,
      securityAlerts: 0,
      complianceScore: 100
    };
  }
  
  updateMetrics(event) {
    switch (event.type) {
      case 'failed_login':
        this.metrics.failedLogins++;
        break;
      case 'suspicious_activity':
        this.metrics.suspiciousActivities++;
        break;
      case 'security_alert':
        this.metrics.securityAlerts++;
        break;
    }
    
    this.updateDashboard();
  }
  
  updateDashboard() {
    // Update real-time dashboard
    this.displayMetrics(this.metrics);
    this.checkThresholds(this.metrics);
  }
  
  checkThresholds(metrics) {
    if (metrics.failedLogins > 10) {
      this.triggerHighAlert('High number of failed login attempts');
    }
    
    if (metrics.suspiciousActivities > 5) {
      this.triggerHighAlert('Multiple suspicious activities detected');
    }
  }
}
