Goal

Detect when an AWS Network Access Control List (NACL) has been created, deleted or modified.

Strategy

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

Triage and response

Determine if the usr with arn: {{@userIdentity.arn}} should have used the API call: {{@evt.name}}.
Contact the user and see if this API call was made by the user.
If the API call was not made by the user:
- Rotate the user credentials and investigate what other API calls.
- Determine what other API calls the user made which were not made by the user.
