What triggers this finding
A CloudWatch log group with retention set to "Never Expire", allowing log data to accumulate indefinitely.
Typical fix
Set a retention period (e.g. 30, 90, or 365 days) appropriate for compliance and debugging needs.
Example savings
Varies by ingestion volume — high-traffic log groups can cost $10–$500+/month without retention.
