Core Security Modules

• InputSanitizer: Prevents injection attacks and path traversal
• AuthSystem: JWT-based authentication with session management
• RateLimiter: DOS protection and abuse prevention
• SecurityAudit: Automated vulnerability scanning

Authentication & Authorization

Implementation

const AuthSystem = require('./security/auth');

const auth = new AuthSystem({
  secretKey: process.env.JWT_SECRET,
  tokenExpiry: '1h',
  refreshExpiry: '7d'
});

// Create user with strong password requirements
await auth.createUser({
  username: 'admin',
  password: 'SecureP@ssw0rd123!',
  email: 'admin@example.com',
  role: 'admin'
});

Best Practices

1. Strong Password Policy

   • Minimum 12 characters
   • Mix of uppercase, lowercase, numbers, symbols
   • No dictionary words or personal information

2. Token Management

   • Short-lived access tokens (1 hour)
   • Secure refresh token rotation
   • Immediate revocation on logout

3. Session Security

   • Secure session storage
   • Session timeout after inactivity
   • Multi-session management

4. Account Protection

   • Account lockout after failed attempts
   • Progressive delays on authentication failures
   • Email notifications for security events

Configuration

# .env - Authentication settings
JWT_SECRET=your-super-secure-random-key-here
AUTH_TOKEN_EXPIRY=1h
AUTH_REFRESH_EXPIRY=7d
AUTH_MAX_LOGIN_ATTEMPTS=5
AUTH_LOCKOUT_DURATION=15m

Input Validation & Sanitization

Always Sanitize User Input

const InputSanitizer = require('./security/sanitizer');

// Path sanitization
const safePath = InputSanitizer.sanitizePath(userInput, basePath);

// Project name validation
const safeProjectName = InputSanitizer.sanitizeProjectName(name);

// Command sanitization
const safeCommand = InputSanitizer.sanitizeCommand(userCommand);

// Configuration values
const safeValue = InputSanitizer.sanitizeConfigValue(value, 'string');

Validation Rules

1. Path Operations

   • Always use absolute paths
   • Prevent directory traversal (../)
   • Validate against allowed directories
   • Check for suspicious patterns

2. Command Execution

   • Whitelist allowed characters
   • Remove command separators (;, |, &)
   • Limit command length
   • Use parameterized execution

3. Configuration Data

   • Type validation
   • Length restrictions
   • Pattern matching
   • Enum validation where applicable

Common Vulnerabilities to Prevent

• Path Traversal: ../../../etc/passwd
• Command Injection: ; rm -rf /
• SQL Injection: '; DROP TABLE users; --
• XSS: <script>alert('xss')</script>
• Prototype Pollution: {"__proto__": {"admin": true}}

Rate Limiting & DOS Protection

Implementation

const { RateLimiters } = require('./security/rate-limiter');

// Different limiters for different operations
const apiLimiter = RateLimiters.createApiLimiter();
const authLimiter = RateLimiters.createAuthLimiter();
const metaAgentLimiter = RateLimiters.createMetaAgentLimiter();

// Check before operation
const identifier = RateLimiter.createIdentifier({
  ip: req.ip,
  userId: req.user?.id,
  operation: 'meta-agent'
});

const result = metaAgentLimiter.check(identifier);
if (!result.allowed) {
  throw new Error(`Rate limit exceeded. Retry after ${result.retryAfter} seconds`);
}

Rate Limiting Strategy

| Operation | Window | Limit | Purpose | |-----------|--------|-------|---------| | API Calls | 15 min | 1000 | General API protection | | Authentication | 15 min | 5 | Brute force prevention | | Installation | 1 hour | 10 | Installation abuse prevention | | Meta-Agent | 1 min | 30 | Resource protection | | File Operations | 1 min | 100 | Filesystem protection |

Configuration

# Rate limiting settings
RATE_LIMIT_API_WINDOW=900000
RATE_LIMIT_API_MAX=1000
RATE_LIMIT_AUTH_WINDOW=900000
RATE_LIMIT_AUTH_MAX=5
RATE_LIMIT_INSTALL_WINDOW=3600000
RATE_LIMIT_INSTALL_MAX=10

Secure Configuration

Environment Variables

# Required security settings
NODE_ENV=production
JWT_SECRET=your-256-bit-secret-key
DATABASE_ENCRYPTION_KEY=your-database-encryption-key
SESSION_SECRET=your-session-secret

# API Keys (never hardcode!)
OPENAI_API_KEY=sk-your-openai-key
ANTHROPIC_API_KEY=sk-your-anthropic-key

# Security headers
SECURITY_HEADERS_ENABLED=true
HELMET_ENABLED=true
CORS_ORIGIN=https://yourdomain.com

# Audit logging
AUDIT_LOG_ENABLED=true
AUDIT_LOG_LEVEL=info
AUDIT_LOG_FILE=/var/log/aiox/audit.log

File Permissions

# Secure file permissions
chmod 600 .env
chmod 600 .aiox/config.json
chmod 600 .aiox/users.json
chmod 600 .aiox/sessions.json
chmod 700 .aiox/
chmod 700 security/

Configuration Validation

// Validate critical configuration on startup
const requiredEnvVars = [
  'JWT_SECRET',
  'NODE_ENV'
];

for (const envVar of requiredEnvVars) {
  if (!process.env[envVar]) {
    throw new Error(`Missing required environment variable: ${envVar}`);
  }
}

// Validate JWT secret strength
if (process.env.JWT_SECRET.length < 32) {
  throw new Error('JWT_SECRET must be at least 32 characters long');
}

Data Protection

Encryption at Rest

const crypto = require('crypto');

class DataEncryption {
  constructor(key) {
    this.key = key;
    this.algorithm = 'aes-256-gcm';
  }

  encrypt(text) {
    const iv = crypto.randomBytes(16);
    const cipher = crypto.createCipher(this.algorithm, this.key, iv);
    
    let encrypted = cipher.update(text, 'utf8', 'hex');
    encrypted += cipher.final('hex');
    
    const authTag = cipher.getAuthTag();
    
    return {
      encrypted,
      iv: iv.toString('hex'),
      authTag: authTag.toString('hex')
    };
  }

  decrypt(encryptedData) {
    const decipher = crypto.createDecipher(
      this.algorithm, 
      this.key, 
      Buffer.from(encryptedData.iv, 'hex')
    );
    
    decipher.setAuthTag(Buffer.from(encryptedData.authTag, 'hex'));
    
    let decrypted = decipher.update(encryptedData.encrypted, 'hex', 'utf8');
    decrypted += decipher.final('utf8');
    
    return decrypted;
  }
}

Sensitive Data Handling

1. API Keys

   • Store in environment variables only
   • Never log or expose in error messages
   • Rotate regularly
   • Use separate keys for different environments

2. User Data

   • Hash passwords with bcrypt (salt rounds ≥ 12)
   • Encrypt PII at rest
   • Implement data retention policies
   • Support data deletion requests

3. Session Data

   • Use secure session storage
   • Implement session timeout
   • Clear sessions on logout
   • Monitor for session hijacking

Logging & Monitoring

Security Event Logging

const winston = require('winston');

const securityLogger = winston.createLogger({
  level: 'info',
  format: winston.format.combine(
    winston.format.timestamp(),
    winston.format.json()
  ),
  transports: [
    new winston.transports.File({ 
      filename: 'logs/security.log',
      level: 'warn'
    }),
    new winston.transports.File({ 
      filename: 'logs/audit.log' 
    })
  ]
});

// Log security events
securityLogger.warn('Authentication failed', {
  username: req.body.username,
  ip: req.ip,
  userAgent: req.get('User-Agent'),
  timestamp: new Date().toISOString()
});

Events to Monitor

• Failed authentication attempts
• Rate limit violations
• Suspicious file access patterns
• Configuration changes
• Permission escalation attempts
• Unusual API usage patterns

Alerting Thresholds

const alertThresholds = {
  failedLogins: 10, // per hour
  rateLimitViolations: 50, // per hour
  suspiciousFileAccess: 5, // per hour
  configChanges: 1, // any change
  errorRate: 0.05 // 5% error rate
};

Network Security

HTTPS Configuration

const https = require('https');
const fs = require('fs');

const options = {
  key: fs.readFileSync('path/to/private-key.pem'),
  cert: fs.readFileSync('path/to/certificate.pem'),
  // Security improvements
  secureProtocol: 'TLSv1_2_method',
  ciphers: 'ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384',
  honorCipherOrder: true
};

https.createServer(options, app).listen(443);

Security Headers

const helmet = require('helmet');

app.use(helmet({
  contentSecurityPolicy: {
    directives: {
      defaultSrc: ["'self'"],
      scriptSrc: ["'self'", "'unsafe-inline'"],
      styleSrc: ["'self'", "'unsafe-inline'"],
      imgSrc: ["'self'", "data:", "https:"]
    }
  },
  hsts: {
    maxAge: 31536000,
    includeSubDomains: true,
    preload: true
  }
}));

CORS Configuration

const cors = require('cors');

app.use(cors({
  origin: process.env.CORS_ORIGIN || 'https://yourdomain.com',
  credentials: true,
  methods: ['GET', 'POST', 'PUT', 'DELETE'],
  allowedHeaders: ['Content-Type', 'Authorization']
}));
