Implement comprehensive audit logging for regulatory compliance with tamper-evident records.
Sample acceptance criteria Landfall generates for this obligation:
- Implementation or documented process meets the reviewed acceptance criteria; identify the tested version and deployment status separately
- Configure defaults from the assessed source and purpose; do not enable data collection or processing merely because this task exists
- Validate behavior for the assessed actors and use cases, including applicable guest or administrator paths
- UI clearly communicates what the feature does to users
- API returns appropriate error codes when feature blocks an action
Evidence an auditor expects
- Technical controlTechnical audit
