What CGPulse checks
A resource passes this rule when retentionInDays must be greater than 89. Anything else is reported as a finding with the evaluated property value attached as evidence.
How to fix it
Set data retention to at least 90 days for adequate security incident investigation. In AWS Console: CloudWatch > Log groups > set retention to 90+ days. See: https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/Working-with-log-groups-and-streams.html
Terraform
resource "aws_cloudwatch_log_group" "{name}" {
retention_in_days = 90
}
