Signed Build Artifacts
Quick Reference
What & Why
Definition
100% of production artifacts cryptographically signed using cosign or similar tool with signature verification enforced.
Business Value
Maintains <10 minute build times while adding security checks and reduces container vulnerabilities by 95% through automated scanning and caching Achieving 100% artifacts signed and verified is a key milestone toward this goal.
Context
This capability is part of the Acceleration milestone's focus on scale automation, embed compliance, improve speed & reliability. Essential for teams targeting DF, LT, CFR improvements.
Success Criteria
100% artifacts signed and verified
Measurement
Artifact signature verification rate in deployment
Evidence
- Signing key management
- Signed artifact registry
- Verification logs
In Practice
Real-World Implementation
Build pipeline signs Docker images with cosign, stores signatures in registry. Deployment verifies signatures before pulling images.

Troubleshooting & FAQs
Common Issues
Issue: Target metric not improving
Solution: Verify measurement is accurate, check if prerequisites are fully implemented, review evidence artifacts for completeness
Issue: Team resistance to adoption
Solution: Start with pilot team, demonstrate value with metrics, provide training and support during transition
Issue: Inconsistent implementation across teams
Solution: Create shared templates and guidelines, establish regular sync meetings, use automation to enforce standards
Frequently Asked Questions
Can we implement this before completing prerequisites?
While possible, it's not recommended. Prerequisites ensure foundational practices are in place, making this capability more effective and easier to adopt.
How long does implementation typically take?
Most capabilities can be implemented within 90 days when tackled as part of the Acceleration milestone. Individual timelines vary based on team size and existing practices.
