Please do NOT create public GitHub issues for security vulnerabilities. This puts all users at risk.

Instead, please use GitHub's Private Security Advisory feature:

1. Go to: https://github.com/sequential-parameter-optimization/spotanomaly2-safe/security/advisories
2. Click "Report a vulnerability"
3. Provide details about the vulnerability

Alternatively, email your findings to:

bartzbeielstein@users.noreply.github.com

with the subject line: [SECURITY] spotanomaly2-safe Vulnerability Report

Include:

• Description of the vulnerability
• Affected version(s)
• Steps to reproduce (if applicable)
• Potential impact
• Suggested fix (if available)

• Acknowledgment: Within 24 hours
• Initial assessment: Within 3 business days
• Fix and patch: Varies based on severity
• Public disclosure: Coordinated after patch is available

Published security advisories can be found in the GitHub Security Advisories section.

• REUSE Compliant: All code contains SPDX license headers
• SPDX: Files use SPDX-License-Identifier headers
• EU AI Act: Support for compliance via MODEL_CARD.md
• Python: Requires Python 3.13+
• OpenSSF: Scorecard monitoring enabled

1. Always use the latest available version from PyPI
2. Review CHANGELOG.md for security patches
3. Monitor GitHub Releases for updates

1. Pin exact versions in requirements.txt or pyproject.toml
2. Use virtual environments (venv or uv)
3. Keep dependencies updated via your dependency management tool
4. Review MODEL_CARD.md for safety-critical considerations

1. Use pre-commit hooks for code quality
2. Enable local GPG commit signing
3. Follow the contribution guidelines
4. Run full test suite before submitting PRs

This project maintains minimal dependencies to reduce the attack surface:

dependencies = [
    "numpy",           # Numerical computation
    "pandas",          # Data handling
    "scikit-learn",    # ML utilities (KMeans, GMM, IsolationForest)
    "scipy",           # Scientific computing
]

Supply Chain Measures:

• All dependencies pinned with compatible release specifiers
• Dependabot enabled for automated dependency updates
• GitHub Actions pinned to specific commit hashes
• REUSE compliance for license tracking
• Regular security scanning via bandit

For contributors, ensure security best practices:

git clone https://github.com/sequential-parameter-optimization/spotanomaly2-safe.git
cd spotanomaly2-safe

# Set up GPG signing (optional but recommended)
git config --local commit.gpgsign true
git config --local tag.gpgsign true

# Install pre-commit hooks
pip install pre-commit
pre-commit install

# Run security checks locally
bandit -r spotanomaly2-safe/

All commits to main and develop branches undergo:

1. REUSE Compliance Check: License header verification
2. Code Quality: ruff, ty
3. Security Scanning: bandit
4. Test Coverage: pytest with coverage reporting
5. Dependency Analysis: Dependabot automated updates
