Installation

# For production environments
npm install pendeck --save

# For development with TypeScript types
npm install pendeck @types/pendeck --save-dev

Requirements:

• Node.js 16.x+
• Express 4.x+
• 512MB+ dedicated memory for analysis workers

Quick Start

const express = require('express');
const pendeck = require('pendeck');

const app = express();
const security = pendeck({
  threatIntel: {
    sources: [
      'https://threatfeed.pendeck.com/v3',
      'file:///opt/pendeck/local-patterns'
    ]
  }
});

// Initialize security layers
security.initialize().then(() => {
  // Apply middleware stack
  app.use(security.middleware.csrfShield());
  app.use(security.middleware.sqlArmor());
  app.use(security.middleware.xssSentinel());
  
  // Your application routes
  app.get('/', (req, res) => res.send('Secure Application'));
  
  app.listen(3000);
});

Environment Variables:

# Enable production security settings
export NODE_ENV=production

# Configure pattern update frequency (seconds)
export PEN_DECK_PATTERN_REFRESH=3600

# Set telemetry sampling rate (0.0-1.0)
export PEN_DECK_TELEMETRY_SAMPLING=0.25

Advanced Configuration

Security Policy Overrides

// config/security.js
module.exports = {
  sqlArmor: {
    detectionThreshold: 0.92,  // Higher precision
    queryAnalysis: {
      maxAstDepth: 7,
      allowTempTables: false
    }
  },
  xssSentinel: {
    decodeDepth: 5,  // Defense against nested encodings
    forbiddenAttributes: ['onload', 'onerror']
  }
};

Custom Pattern Sources

# pendeck-patterns.yml
sources:
  - url: https://internal.threatfeed.company/v2
    authToken: ${INTERNAL_THREAT_TOKEN}
    refresh: 600  # 10 minutes
  - url: file:///security/custom-patterns
    format: pendeck-v2

API Reference

Middleware Options

CSRF Shield

security.middleware.csrfShield({
  cookie: {
    domain: '.example.com',
    sameSite: 'strict'
  },
  token: {
    algorithm: 'hmac-sha256',
    keyRotation: '72h'  // Auto-rotate keys every 3 days
  }
});

SQL Armor

security.middleware.sqlArmor({
  detection: {
    mode: 'block',  // Options: log|block|challenge
    challenge: {
      ttl: 30000  // CAPTCHA timeout
    }
  },
  parser: {
    dialect: 'ansi',  // Supported: ansi|mysql|postgresql
    maxStatements: 3
  }
});

Detectors API

Query Analyzer

const { score, verdict } = security.detectors.queryAnalyzer(
  'SELECT * FROM users WHERE 1=1',
  { context: 'raw-query' }
);

Payload Decoder

const analysis = security.detectors.decodePayload(
  '%3Cscript%3Ealert(1)%3C%2Fscript%3E',
  { contentType: 'text/html' }
);

Utilities

Threat Monitoring

security.monitoring.on('attack', (event) => {
  console.log(`Blocked ${event.type} attack from ${event.ip}`);
});

// Export PCAP forensic data
security.monitoring.captureTraffic({
  output: '/var/log/pendeck/pcap',
  retention: '7d'
});

Performance Considerations

Benchmark Results (4-core CPU/8GB RAM):

| Middleware   | Latency (p50) | Throughput  | Memory Usage |
|--------------|---------------|-------------|--------------|
| CSRF Shield  | 2.1ms         | 12k req/s   | 45MB         |
| SQL Armor    | 5.8ms         | 8.4k req/s  | 210MB        |
| XSS Sentinel | 7.2ms         | 6.1k req/s  | 180MB        |

Optimization Strategies: 1. Enable Adaptive Sampling:

security.configure({
  performance: {
    sampling: {
      enabled: true,
      rate: 0.3  // Analyze 30% of requests
    }
  }
});

2. Use Worker Pools:

   security.initialize({
     workers: {
       count: 4,       // Match CPU cores
       memoryLimit: '1G'
     }
   });

Security Best Practices

1. Defense-in-Depth Implementation:

   // Layered security configuration
   security.configure({
     strategy: 'defense-depth',
     layers: [
       { name: 'input-validation', weight: 0.3 },
       { name: 'pattern-detection', weight: 0.4 },
       { name: 'behavior-analysis', weight: 0.3 }
     ]
   });

2. Regular Pattern Updates:

   # Manual pattern refresh
   curl -X POST http://localhost:3000/_pendeck/refresh-patterns \
     -H "Authorization: Bearer $ADMIN_TOKEN"

3. Threat Hunting Interface:

   // Enable GraphQL security endpoint
   security.enableDashboard({
     path: '/_security',
     authentication: 'oidc'
   });
