Overview

A config rule that checks whether running instances are using specified AMIs. Specify a list of approved AMI IDs. Running instances with AMIs that are not on this list are noncompliant.

This config rule supports Auto Remediation actions using SSM Automation triggered with CloudWatch Events. The following actions are supported:

  • Stop Instance: Non-compliant instances are stopped.
  • Terminate Instance: Non-compliant instances are terminated. (Be careful when selecting this option to not accidentally terminate existing resources).

In addition to an action, a notification using an SNS Topic can be added to send a custom message when a non-compliant resource is detected.
