Why this matters

Public S3 buckets are a critical security risk — they expose data to the internet. AWS has had multiple high-profile breaches from misconfigured buckets. This should be audited monthly.

⚠ Always verify resources are genuinely unused before deleting. Check with your team — a "stopped" instance may be intentional.
