What CGPulse checks
A resource passes this rule when vpcConfig.vpcId must be set true. Anything else is reported as a finding with the evaluated property value attached as evidence.
How to fix it
Deploy the Lambda function inside a VPC to securely access private resources. In AWS Console: Lambda > Configuration > VPC > select VPC and subnets. See: https://docs.aws.amazon.com/lambda/latest/dg/configuration-vpc.html
Terraform
resource "aws_lambda_function" "{name}" {
vpc_config {
subnet_ids = [aws_subnet.private.id]
security_group_ids = [aws_security_group.lambda.id]
}
}
