Goal

Detect when an EBS encryption is disabled by default.

Strategy

Monitor CloudTrail and detect when EBS encryption is disabled by default via the following API call:

Triage and response

  1. Determine which user in your organization owns the API key that made this API call.
  2. Contact the user and let them know that it is best practice to enable EBS encryption by default.
  3. Re-enable EBS encryption by default.
