Security

Overview

ReCloud implements enterprise-grade security measures across all system components, ensuring data protection, access control, and compliance with industry standards.

Authentication & Authorization

API Key Management

Secure Key Storage

• Environment Variables: API keys stored securely in environment variables
• Key Rotation: Automated key rotation with minimal downtime
• Access Logging: Comprehensive audit trails for key usage

Key Validation

const validateApiKey = (req, res, next) => {
  const apiKey = req.headers.authorization?.replace('Bearer ', '') ||
                 req.headers['x-api-key'] ||
                 req.body.apiKey;

  if (!apiKey || !isValidApiKey(apiKey)) {
    return res.status(401).json({
      error: 'Valid API key required',
      code: 'INVALID_API_KEY'
    });
  }

  req.apiKey = apiKey;
  next();
};

Role-Based Access Control

User Roles

• Admin: Full system access and configuration
• Developer: Tool execution and project management
• User: Basic tool access with restrictions

Permission Matrix

const permissions = {
  admin: {
    system: ['read', 'write', 'delete'],
    tools: ['*'],
    users: ['manage'],
    config: ['read', 'write']
  },
  developer: {
    system: ['read'],
    tools: ['execute', 'manage_own'],
    users: ['read_own'],
    config: ['read']
  },
  user: {
    system: ['read'],
    tools: ['execute_basic'],
    users: ['read_own'],
    config: []
  }
};

Data Protection

Encryption

Data at Rest

• Database Encryption: Transparent Data Encryption (TDE)
• File System Encryption: Encrypted storage for sensitive files
• Configuration Encryption: Encrypted environment variables

Data in Transit

• TLS 1.3: End-to-end encryption for all communications
• Certificate Pinning: Additional security for API connections
• Secure Headers: HTTP security headers implementation

Input Validation

Schema Validation

import { z } from 'zod';

// Tool execution schema
const toolExecutionSchema = z.object({
  toolName: z.string().min(1).max(100),
  parameters: z.record(z.any()),
  timeout: z.number().min(1000).max(300000).optional()
});

// Validate input
const validatedInput = toolExecutionSchema.parse(req.body);

Sanitization

import DOMPurify from 'dompurify';

// Sanitize user inputs
const sanitizeInput = (input: string): string => {
  return DOMPurify.sanitize(input, {
    ALLOWED_TAGS: [],
    ALLOWED_ATTR: []
  });
};

Network Security

Access Control

Request Rate Limiting

• API Rate Limits: Configurable limits per endpoint and user
• Burst Protection: Prevention of sudden traffic spikes
• Distributed Limiting: Cluster-wide rate limit enforcement
• Graduated Responses: Progressive delay for excessive requests

Security Monitoring

Intrusion Detection

Log Analysis

// Security event monitoring
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'
    })
  ]
});

// Monitor suspicious patterns
app.use((req, res, next) => {
  const suspiciousPatterns = [
    /\.\./,  // Path traversal
    /<script/i,  // XSS attempts
    /union.*select/i,  // SQL injection
    /eval\(/,  // Code injection
  ];

  const requestData = `${req.url} ${JSON.stringify(req.body)} ${req.get('User-Agent') || ''}`;

  suspiciousPatterns.forEach(pattern => {
    if (pattern.test(requestData)) {
      securityLogger.warn('Suspicious request detected', {
        ip: req.ip,
        method: req.method,
        url: req.url,
        pattern: pattern.source,
        userAgent: req.get('User-Agent')
      });
    }
  });

  next();
});

Automated Alerts

// Security alert system
const alertSystem = {
  async sendAlert(severity: 'low' | 'medium' | 'high' | 'critical', message: string, details: any) {
    // Send to monitoring system (Datadog, PagerDuty, etc.)
    // Send email alerts for high/critical severity
    // Log to security dashboard
  }
};

// Example usage
if (failedLoginAttempts > 5) {
  await alertSystem.sendAlert('high', 'Multiple failed login attempts', {
    ip: req.ip,
    attempts: failedLoginAttempts,
    timeWindow: '5 minutes'
  });
}

Compliance

GDPR Compliance

Data Processing

• Data Minimization: Only collect necessary user data
• Purpose Limitation: Data used only for stated purposes
• Storage Limitation: Data retained only as long as necessary
• Data Portability: Users can export their data

User Rights

// GDPR compliance endpoints
app.get('/gdpr/data', authenticate, async (req, res) => {
  // Return all user data
  const userData = await getUserData(req.user.id);
  res.json({ data: userData });
});

app.delete('/gdpr/data', authenticate, async (req, res) => {
  // Delete all user data (right to be forgotten)
  await deleteUserData(req.user.id);
  res.json({ message: 'Data deleted successfully' });
});

SOC 2 Compliance

Security Controls

• Access Control: Multi-factor authentication for admin access
• Change Management: Version control and deployment procedures
• Incident Response: Documented security incident procedures
• Regular Audits: Quarterly security assessments

Encryption Standards

Key Management

// Key rotation system
class KeyManager {
  private currentKey: string;
  private previousKey: string;

  async rotateKeys() {
    this.previousKey = this.currentKey;
    this.currentKey = await generateNewKey();

    // Update configuration
    await updateConfig('API_KEY', this.currentKey);

    // Grace period for old key
    setTimeout(() => {
      this.previousKey = null;
    }, 24 * 60 * 60 * 1000); // 24 hours
  }

  validateKey(key: string): boolean {
    return key === this.currentKey || key === this.previousKey;
  }
}
