🔐 Reporting Security Vulnerabilities

The LOOP team takes security seriously. We appreciate your efforts to responsibly disclose your findings.

Where to Report

DO NOT create public GitHub issues for security vulnerabilities.

Please report security vulnerabilities by emailing:

• alphin@mycel-ai.de (GitHub: @alpha912)

What to Include

Your report should include:

• Description of the vulnerability
• Steps to reproduce
• Potential impact
• Suggested fix (if any)
• Your contact information

Response Timeline

• Initial Response: Within 48 hours
• Status Update: Within 5 business days
• Resolution Target: 30-90 days depending on severity

🛡️ Security Considerations

Node Security

Transport Layer

• ✅ REQUIRED: TLS 1.3 or higher for all connections
• ✅ REQUIRED: Valid SSL certificates (no self-signed in production)
• ✅ REQUIRED: Perfect Forward Secrecy
• ✅ REQUIRED: HSTS headers with minimum 1-year duration

Authentication & Authorization

• ✅ REQUIRED: OAuth 2.0 / OpenID Connect for user authentication
• ✅ REQUIRED: Mutual TLS or signed requests for node-to-node
• ✅ REQUIRED: API tokens must expire (max 24 hours)
• ✅ REQUIRED: Rate limiting on all endpoints

Data Protection

• ✅ REQUIRED: No personal data in MaterialDNA
• ✅ REQUIRED: Encrypt sensitive data at rest
• ✅ REQUIRED: Audit logs must be immutable
• ✅ REQUIRED: GDPR compliance for EU nodes

Cryptographic Requirements

Signing

• Algorithm: Ed25519 (required)
• Key Size: 256 bits
• Libraries: Use well-tested implementations only

Hashing

• Password Hashing: Argon2id (recommended) or bcrypt
• Data Integrity: SHA-256 minimum
• Merkle Trees: For audit trails

Random Number Generation

• REQUIRED: Cryptographically secure RNG only
• Sources: /dev/urandom or equivalent
• Testing: Diehard tests for custom implementations

API Security

Input Validation

// Example validation middleware
const validateMaterialDNA = (req, res, next) => {
  const pattern = /^[A-Z]{2}-[A-Z]{3}-\d{4}-[A-Z]+-[A-Z0-9]{6,}$/;
  if (!pattern.test(req.body.id)) {
    return res.status(400).json({error: 'Invalid MaterialDNA format'});
  }
  next();
};

Output Encoding

• JSON responses only
• Proper Content-Type headers
• No sensitive data in error messages

CORS Policy

const corsOptions = {
  origin: function (origin, callback) {
    if (allowedOrigins.indexOf(origin) !== -1 || !origin) {
      callback(null, true);
    } else {
      callback(new Error('Not allowed by CORS'));
    }
  },
  credentials: true,
  maxAge: 86400
};

Database Security

Access Control

• Principle of least privilege
• Separate read/write accounts
• Network isolation

Backup & Recovery

• Encrypted backups
• Regular restore testing
• Geographically distributed copies

Monitoring & Incident Response

Logging Requirements

• Failed authentication attempts
• Rate limit violations
• Invalid MaterialDNA registrations
• Cross-node settlement failures

Alerting Triggers

• Multiple failed auth attempts
• Unusual traffic patterns
• Certificate expiry warnings
• System resource exhaustion
