Ensure Cloud Object Storage buckets are not publicly accessible

심각레벨 1자동ibmcloud

설명

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.

점검 방법

감사 방식: 셸 명령

shell

grp=$(ibmcloud iam access-groups --output json 2>/dev/null) || exit 1
if ! printf '%s\n' "$grp" | grep -q '"Public Access"'; then echo compliant; exit 0; fi
out=$(ibmcloud iam access-group-policies "Public Access" --output json 2>/dev/null) || exit 1
n=$(printf '%s\n' "$out" | grep -c '"cloud-object-storage"' || true)
[ "$n" -eq 0 ] && echo compliant

예상 출력: compliant

Remove the cloud-object-storage policies from the Public Access group (ibmcloud iam access-group-policy-delete "Public Access" <policy-id>) and disable public access in the COS console.
