# Security Policy

## 🛡️ Our Security Commitment

TrojanHorse.js is a security-focused threat intelligence library. We take security seriously and have implemented multiple layers of protection to ensure the safety of your data and API keys.

## 🔐 Security Features

### Zero-Knowledge Architecture
- **No Plaintext Storage**: API keys are never stored in plaintext, even in memory
- **Client-Side Encryption**: All sensitive data is encrypted using industry-standard algorithms
- **Secure Memory Handling**: Automatic cleanup and erasure of sensitive data
- **Forward Secrecy**: Key rotation capabilities with automatic cleanup of old keys

### Cryptographic Standards
- **AES-256-GCM**: Advanced Encryption Standard with Galois/Counter Mode
- **PBKDF2**: Password-Based Key Derivation Function 2 with high iteration counts
- **SHA-256**: Secure Hash Algorithm for integrity verification
- **HMAC-SHA256**: Hash-based Message Authentication Code for data authentication
- **TLS 1.3**: Minimum encryption for all network communications

### Enterprise Security Controls
- **Certificate Pinning**: Prevents man-in-the-middle attacks
- **Request Signing**: HMAC signatures for API request authenticity
- **Rate Limiting**: Protection against abuse and DoS attacks
- **Input Validation**: Comprehensive validation of all inputs
- **Output Encoding**: Prevention of injection attacks
- **CSRF Protection**: Cross-Site Request Forgery prevention
- **XSS Prevention**: Cross-Site Scripting mitigation

## 🔍 Security Assessments

### Automated Security Testing
- **Dependency Scanning**: Regular checks for vulnerable dependencies
- **Static Code Analysis**: Automated code security analysis
- **Dynamic Testing**: Runtime security testing
- **Penetration Testing**: Regular third-party security assessments

### Compliance Standards
- **OWASP Top 10**: Full compliance with web application security risks
- **SOC 2 Type II**: Compatible with System and Organization Controls
- **ISO 27001**: Information security management standards
- **NIST Cybersecurity Framework**: Aligned with federal cybersecurity standards

## 🚨 Vulnerability Reporting

We encourage responsible disclosure of security vulnerabilities. If you discover a security issue:

### ✅ DO
- Email security@trojanhorse-js.dev with detailed information
- Include steps to reproduce the vulnerability
- Provide a proof of concept if possible
- Allow 90 days for remediation before public disclosure
- Work with our security team to verify and fix the issue

### ❌ DON'T
- Create public GitHub issues for security vulnerabilities
- Publicly disclose vulnerabilities before remediation
- Attempt to access data that doesn't belong to you
- Perform testing that could damage systems or data
- Spam or social engineer our team members

## 📧 Security Contact

**Primary Contact**: security@trojanhorse-js.dev  
**PGP Key**: [Available on our website]  
**Response Time**: Within 24 hours for critical vulnerabilities  

## 🏆 Security Bounty Program

We appreciate the security research community and offer rewards for qualifying vulnerability reports:

### Severity Levels

## 🛠️ Security Best Practices for Users

### API Key Management
```javascript
// ✅ DO - Use environment variables
const apiKeys = {
  alienVault: process.env.TROJANHORSE_ALIENVAULT_KEY,
  crowdsec: process.env.TROJANHORSE_CROWDSEC_KEY
};

// ❌ DON'T - Hardcode API keys
const apiKeys = {
  alienVault: 'your-api-key-here', // Never do this!
};
```

### Secure Configuration
```javascript
// ✅ DO - Use maximum security settings
const trojan = new TrojanHorse({
  security: {
    mode: 'fort-knox',
    httpsOnly: true,
    certificatePinning: true,
    minTlsVersion: '1.3'
  },
  vault: {
    autoLock: true,
    lockTimeout: 300000, // 5 minutes
    iterations: 100000 // High iteration count
  }
});
```

### Network Security
```javascript
// ✅ DO - Validate SSL certificates
const trojan = new TrojanHorse({
  security: {
    validateCertificates: true,
    certificatePinning: true,
    httpsOnly: true
  }
});
```

### Data Handling
```javascript
// ✅ DO - Enable audit logging
const trojan = new TrojanHorse({
  audit: {
    enabled: true,
    logLevel: 'info',
    piiMasking: true,
    encryptLogs: true
  }
});
```
