## Goal{% #goal %}

Detects when an AWS Kinesis Firehose Destination is modified.

## Strategy{% #strategy %}

The rule monitors AWS Kinesis Firehose logs `@eventSource:firehose.amazonaws.com` and detects when the `@evt.name` is `UpdateDestination`.

## Triage and response{% #triage-and-response %}

1. Determine if `{{@userIdentity.arn}}` is expected to perform the `{{@evt.name}}` API call on the account: `{{@userIdentity.accountId}}`.
1. If the API call was not made by the user, rotate the user credentials and investigate what other APIs were successfully accessed.
   - Rotate the credentials.
   - Investigate if the same credentials made other unauthorized API calls.
