Ensure Cloud Object Storage buckets are not publicly accessible

KritičnaNivo 1Automatskaibmcloud

Opis

COS public access is granted through policies on the account's Public Access group. That group must have no cloud-object-storage policies (passes if the group does not exist). Read-only ibmcloud CLI calls using the current CLI session and targeted region (ibmcloud login, or IBMCLOUD_API_KEY); JSON output is parsed with grep/sed/awk. A missing CLI, plugin or session fails the check.
