VIEW RULE IN DATADOG VIEW SIGNALS

Goal

Detect when an AWS Route Table has been created or modified.

Strategy

This rule lets you monitor CloudTrail and detect when an AWS Route Table has been created or modified with one of the following API calls:

• CreateRoute
• CreateRouteTable
• ReplaceRoute
• ReplaceRouteTableAssociation
• DeleteRouteTable
• DeleteRoute
• DisassociateRouteTable

Triage and response

1. Determine if {{@userIdentity.arn}} is expected to perform the {{@evt.name}} API call.
2. Contact the principal owner and see if this was an API call which was made by the user.
3. If the API call was not made by the user, rotate the user credentials and investigate what other APIs were successfully accessed.
