VIEW RULE IN DATADOG VIEW SIGNALS

Goal

Detect when a user deletes an Amazon Detective behavior graph.

Strategy

This rule lets you monitor this CloudTrail API call to detect if a user has deleted an Amazon Detective behavior graph:

• DeleteGraph

Triage and response

1. Determine if the behavior graph should have been deleted.
2. Determine which user ({{@userIdentity.arn}}) in your organization deleted the behavior graph.
3. If the user did not make the API call:
   • Rotate the credentials.
   • Investigate if the same credentials made other unauthorized API calls.
