Security Scanning

Quick Start

• Secrets: fail fast; rotate on exposure.
• Dependencies: gate critical/high; automate updates.
• SAST: start high-signal; ratchet over time.
• Open Source Safety: score components on three axes — license tier, severity-weighted CVEs, obsolescence.
• Exceptions: require reason, owner, and expiry.

Open Source Safety

Third-party component risk is more than "vulnerable: yes/no". Evaluate each component on three independent dimensions and gate on the worst:

• License risk: HIGH = strong copyleft / GPL/AGPL/LGPL (whole-app disclosure risk); MEDIUM = weak copyleft / MPL, EPL (modification disclosure only); LOW = permissive / MIT, Apache-2.0, BSD. Unknown/NOASSERTION → treat as HIGH until identified.
• CVE weighting: weight by severity (critical ≫ high ≫ medium ≫ low) rather than raw counts; critical/high block, medium/low track with owner + expiry.
• Obsolescence: score the gap to latest version; majors-behind or unmaintained upstream is elevated risk.

See references/open-source-safety.md for the full framework, tier tables, the CVE weighting model, obsolescence scoring, and the transitive-dependency trust model.
