🎓 Best Practices

1. Compliance by Design — Build compliance into architecture from the start
2. Automate Evidence Collection — Don’t rely on manual audit trail generation
3. Continuous Monitoring — Compliance is ongoing, not annual
4. Document Everything — Auditors need evidence, not just assertions
5. Regular Training — Keep team updated on compliance requirements
6. Third-Party Risk — Ensure vendors are compliant (BAAs for HIPAA, DPAs for GDPR)
7. Test Controls — Regularly validate that controls work as intended
8. Layered Controls — Defense in depth (multiple controls for critical data)
