## Response Timeline

We are committed to the following response times:

| Severity   | Initial Response | Triage Complete | Fix Target | Public Disclosure |
|------------|-----------------|-----------------|------------|-------------------|
| Critical   | 24 hours        | 48 hours        | 7 days     | 30 days after fix |
| High       | 48 hours        | 5 days          | 30 days    | 60 days after fix |
| Medium     | 5 days          | 14 days         | 60 days    | 90 days after fix |
| Low        | 7 days          | 30 days         | Next release | 120 days after fix |

**Coordinated Disclosure:** We follow a 90-day coordinated disclosure policy. We will work with you to determine an appropriate public disclosure date after a fix is released.

### Response Process

1. **Acknowledgment:** We will acknowledge receipt within the timeframe above
2. **Validation:** We will validate and reproduce the issue
3. **Triage:** We will assess severity and impact
4. **Remediation:** We will develop and test a fix
5. **Release:** We will release a patched version
6. **Disclosure:** We will publish a security advisory after the fix is widely deployed

## Security Best Practices for Users

### Mobile App Users

1. **Download from Official Sources Only**
   - GitHub Releases: https://github.com/Dezirae-Stark/QuantumTrader-Pro/releases
   - Verify APK signatures and checksums before installation

2. **Keep Software Updated**
   - Enable automatic updates or check regularly for new releases
   - Review changelogs for security fixes

3. **Use Strong Credentials**
   - Never reuse demo credentials for production accounts
   - Use unique, complex passwords
   - Enable biometric authentication if available

4. **Secure Your Device**
   - Keep Android OS updated
   - Use device encryption
   - Install from official app stores when possible

### Developers and Contributors

1. **Never Commit Secrets**
   - Use environment variables for credentials
   - Enable pre-commit hooks for secret scanning
   - Review diffs before committing

2. **Dependency Management**
   - Keep dependencies updated
   - Review security advisories for dependencies
   - Use lock files (package-lock.json, build.gradle.lockfile)

3. **Code Review**
   - All code changes require review
   - Focus on authentication, authorization, and data handling
   - Use automated security scanners in CI/CD

4. **Secure Development Environment**
   - Use encrypted disk storage
   - Secure API tokens and SSH keys
   - Isolate test environments from production

### Bridge Server Operators

1. **Use TLS/HTTPS**
   - Never run bridge server over HTTP in production
   - Use valid TLS certificates
   - Implement certificate pinning in mobile app

2. **Authentication Required**
   - Enable JWT or mutual TLS authentication
   - Rotate credentials regularly
   - Use short-lived tokens

3. **Network Security**
   - Run behind firewall or VPN
   - Implement rate limiting
   - Log security events (without logging credentials)

4. **Regular Updates**
   - Keep Node.js and npm packages updated
   - Monitor security advisories for Express, ws, and other dependencies
   - Apply patches promptly

## Security Features

### Current Security Measures

- **Android App**
  - EncryptedSharedPreferences for credential storage

### Roadmap

Planned security enhancements:

- [ ] End-to-end encryption for sensitive data in transit
- [ ] Hardware security module (HSM) integration for key storage
- [ ] Security audit by third-party firm
- [ ] Bug bounty program launch
- [ ] Penetration testing of mobile app and bridge
- [ ] Formal threat modeling and risk assessment

## Compliance and Certifications

**Current Status:** Pre-certification

**Planned Compliance:**

- OWASP Application Security Verification Standard (ASVS) Level 2
- CWE/SANS Top 25 mitigation

**Not Financial Services Compliant:** This software is for educational and research purposes only. It is not certified for production financial trading.
