Goal

Detect when a CloudWatch Log Group is deleted.

Detect a successful @evt.name:DeleteLogGroup event.

Ensure that the {{@requestParameters.logGroupName}} log group is not used for auditing or security purposes.
If it is then:
- Ensure that the user: {{@userIdentity.session_name}} should be making this API call to your {{env}} environment.
- Consider adding to the allowlist the log group name: {{@requestParameters.logGroupName}} through a suppression list.
If not, begin your company’s IR process and investigate.
