Goal

Detect when a KMS (Key Management Service) key is deleted or scheduled for deletion.

This rule lets you monitor these CloudTrail API calls to detect if an attacker is deleting KMS keys:

Determine if user ARN: {{@userIdentity.arn}} in your organization should be making this call.
If the user did not make the API call:
- Rotate the credentials.
- Use the Cloud SIEM - User Investigation OOTB dashboard to investigate other potential unauthorized API calls from this user.
