## Key Takeaways

- Audit logs are a product feature for regulated workflows.
- Capture hashes and versions so outputs are defensible.
- Use S3 versioning and append only logs.
- Store review actions and approvals as explicit events.

If an AI system affects legal, financial, or compliance outcomes, you need to answer: what happened, when, why, and who approved it. This post outlines audit logging and provenance patterns for AWS plus MongoDB based systems.

## What to capture in an audit log

At minimum:

- Actor (system, user, service)
- Timestamp
- Action (state transition)
- Input pointers and hashes
- Output pointers
- Model or ruleset version

## Append only, never overwrite

An audit log should be append only. If something changes, you write a new event.

This reduces risk and simplifies investigations.

## AWS storage patterns

- Store raw documents in S3 with versioning
- Store logs in CloudWatch and export if needed

References:

- S3 versioning: [https://docs.aws.amazon.com/AmazonS3/latest/userguide/Versioning.html](https://docs.aws.amazon.com/AmazonS3/latest/userguide/Versioning.html)
- Amazon CloudWatch Logs: [https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/WhatIsCloudWatchLogs.html](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/WhatIsCloudWatchLogs.html)

## MongoDB patterns

MongoDB can store:

- Audit events (append only)
- Workflow state per document
- Review and approval actions

Useful features:

- Change streams for downstream consumers

## Compliance baselines

Map controls early.

zed in logs, store pointers where possible, and implement deletion workflows that respect legal requirements.

**Q: Should we log model prompts and responses?** Sometimes yes, but treat them as sensitive. Apply encryption and access controls, and consider redaction.

## FAQs

**Q: How long should we retain audit logs?** Retention depends on your domain and policy. Design for configurable retention with legal hold capability.

**Q: How do we handle privacy requests?** Keep personal data minimi

**Q: What should we link to internally?** A: Link to relevant solution pages like Computer Vision or Document Intelligence, and only link to published blog URLs on the main domain. Avoid staging links.
