sourceIdentifier property
For AWS Config managed rules, a predefined identifier from a list. For
example, IAM_PASSWORD_POLICY is a managed rule. To reference a
managed rule, see Using
AWS Managed Config Rules.
For custom rules, the identifier is the Amazon Resource Name (ARN) of the
rule's AWS Lambda function, such as
arn:aws:lambda:us-east-2:123456789012:function:custom_rule_name.
