Vulnerability Scanning

This project uses automated security scanning as part of our CI/CD pipeline to ensure container images are free from known vulnerabilities.

Scanning Tools

• Trivy: Primary vulnerability scanner for container images
• SBOM Generation: Software Bill of Materials for supply chain transparency
• GitHub Security: Integration with GitHub's security features

Security Gates

Our CI pipeline implements the following security gates:

Severity	Action
CRITICAL	❌ Block deployment - Build fails immediately
HIGH	⚠️ Warning - Logged but build continues if < 5 vulnerabilities
MEDIUM/LOW	✅ Allow - Logged for monitoring

Security Artifacts

Each build generates:

1. SARIF Report - Uploaded to GitHub Security tab
2. Human-readable Report - Stored as build artifact
3. SBOM (SPDX) - Software Bill of Materials
4. Vulnerability Database - Updated regularly

Customizing Security Thresholds

To modify security gates, update the CI workflow:

# Example: Block on 3+ HIGH vulnerabilities instead of 5
- name: Security gate - Warn on HIGH vulnerabilities
  if: steps.vuln-check.outputs.high-count > 3

Vulnerability Management

1. Critical/High Issues: Must be addressed before deployment
2. Medium Issues: Addressed in next sprint
3. Low Issues: Monitored and addressed during maintenance windows

Reporting Security Issues

If you discover a security vulnerability, please report it to:

• Email: [email protected]
• Create a private security advisory on GitHub

Updates and Maintenance

• Vulnerability database updated daily
• Security policies reviewed quarterly
• SBOM generated for every release

Supply Chain Security

SBOM (Software Bill of Materials)

Every container image includes:

• All installed packages and versions
• Dependency relationships
• License information
• Source repositories

Image Signing

Consider implementing image signing for production deployments:

# Example with Cosign
cosign sign --key cosign.key $IMAGE_TAG

Base Image Security

• Use minimal base images (python:3.11-slim)
• Regular base image updates
• Non-root container execution
• Read-only root filesystem when possible
