The Refactored DuoFormer project takes security seriously. This document outlines our security practices and how to report security vulnerabilities.

We provide security updates for the following versions:

If you discover a security vulnerability, please follow these steps:

• Do not report security vulnerabilities through public GitHub issues
• Do not discuss the vulnerability in public forums or social media

Send an email to: security@duoformer-project.com (or create a private security advisory)

Include the following information:

• Description of the vulnerability
• Steps to reproduce the issue
• Potential impact assessment
• Any suggested fixes (if available)

• Initial Response: Within 48 hours
• Status Update: Within 7 days
• Resolution Timeline: Varies based on complexity, typically 30-90 days

• Static Analysis: Automated security scanning with bandit
• Dependency Scanning: Regular updates and vulnerability checks
• Code Review: All changes reviewed for security implications
• Type Safety: Comprehensive type checking with mypy

• Data Validation: All user inputs validated and sanitized
• Configuration Validation: Comprehensive config parameter checking
• File Path Validation: Secure file handling with path traversal protection
• Model Input Validation: Medical image input validation and preprocessing

• Pinned Versions: All dependencies pinned to specific versions
• Regular Updates: Dependencies updated regularly for security patches
• Minimal Dependencies: Only necessary dependencies included
• Trusted Sources: Dependencies sourced from official repositories

• Base Images: Official, minimal base images used
• Layer Scanning: Docker images scanned for vulnerabilities
• Non-Root User: Containers run as non-root user when possible
• Secrets Management: No hardcoded secrets in containers

# Always verify package integrity
pip install --require-hashes -r requirements.txt

# Use virtual environments
python -m venv duoformer-env
source duoformer-env/bin/activate  # Linux/Mac
# or
duoformer-env\Scripts\activate     # Windows

• Medical Data: Ensure compliance with HIPAA/GDPR when handling medical images
• Data Encryption: Encrypt sensitive data at rest and in transit
• Access Control: Implement proper access controls for medical datasets
• Audit Logging: Enable comprehensive logging for audit trails

• Model Validation: Validate model checkpoints before loading
• Secure Storage: Store trained models securely with appropriate access controls
• Version Control: Track model versions and changes
• Inference Security: Validate inputs during model inference

# Use secure configurations
export JUPYTER_TOKEN="your-secure-token-here"
export JUPYTER_PASSWORD_HASH="your-hashed-password"

# Enable HTTPS
jupyter lab --certfile=mycert.pem --keyfile=mykey.key

• PHI Protection: Ensure Protected Health Information is properly anonymized
• Compliance: Follow relevant medical data regulations (HIPAA, GDPR, etc.)
• Data Minimization: Only process necessary medical data
• Secure Deletion: Implement secure data deletion procedures

• Data Poisoning: Be aware of potential data poisoning attacks
• Model Inversion: Consider model inversion attack risks
• Adversarial Examples: Implement defenses against adversarial inputs
• Model Extraction: Protect against model extraction attempts

• Network Security: Use secure network configurations
• Authentication: Implement strong authentication mechanisms
• Authorization: Proper role-based access control
• Monitoring: Continuous security monitoring and alerting

We use the following tools for security scanning:

• Bandit: Python AST security scanner
• Safety: Python dependency vulnerability scanner
• Docker Scout: Container vulnerability scanning
• CodeQL: Semantic code analysis

• OWASP Top 10
• Python Security Guidelines
• Docker Security Best Practices
• Medical AI Security Guidelines

We recognize security researchers who help improve our security:

• Your name could be here!
