| "Description": "This check ensures that the 'cluster-admin' role, which provides wide-ranging powers, is used only where necessary. The 'cluster-admin' role grants super-user access to perform any action on any resource, including all namespaces. It should be applied cautiously to avoid excessive privileges.", | ||

| "Text": "Audit and assess the use of 'cluster-admin' role in all ClusterRoleBindings. Ensure it is assigned only to subjects that require such extensive privileges. Consider using more restrictive roles wherever possible.", | ||

Include a specific link instead of a generic one about etcd security.
