Cloud Storage Misconfiguration Checklist

Misconfigured object storage still causes avoidable data leaks. Use this checklist to find high-impact issues quickly.

1) Public access controls

Block public ACLs and bucket policies unless explicitly required and approved.

2) Least-privilege IAM

Service identities should only access required buckets/prefixes and actions.

3) Encryption defaults

Enable at-rest encryption and verify key-management settings are consistent.

4) Logging and audit trails

Turn on object access logging and alert on unusual download spikes or cross-region access.

5) Lifecycle and stale data

Expire outdated objects and remove old snapshots/backups that no longer need retention.

High-value weekly checks

Keep storage risk visible

Pair exposure checks with monthly reporting to catch drift before it becomes a breach.
