  name: CloudFormation Termination Protection - Disabled
  author: DhiyaneshDK
  severity: medium
  description: |
    Ensure that Termination Protection safety feature is enabled for your Amazon CloudFormation stacks in order to protect them from being accidentally deleted.
  impact: |
    Disabled termination protection increases the risk of accidental deletion of critical CloudFormation stacks.
  remediation: |
    Enable termination protection for critical CloudFormation stacks by setting TerminationProtection to true in the stack settings, preventing accidental deletions.
