    Ensure that Deletion Protection safety feature is enabled for your Amazon Gateway Load Balancers (GWLBs) in order to protect the load balancers from being accidentally deleted.
  impact: |
    Disabling delete protection on an Elastic Load Balancer (ELB) increases the risk of accidental or intentional deletion of the load balancer.
  remediation: |
    Enable Server-Side Encryption (SSE) on the queue to protect sensitive data by encrypting it at rest using AWS KMS.
