  description: |
    Ensure that all Amazon CloudWatch alarms have actions enabled (ActionEnabled: true) to respond to state changes.
  impact: |
    Without actions enabled, CloudWatch alarms cannot perform automated actions in response to state changes, potentially missing critical alerts.
  remediation: |
    Enable actions for each CloudWatch alarm by setting the ActionEnabled parameter to true, allowing for automated responses to alarms.
