Ensure Cloud SQL instances do not have public IPs

높음레벨 2자동gcp

설명

A public IPv4 address exposes the instance to the Internet, guarded only by authorised networks. Every instance must have ipConfiguration.ipv4Enabled false (private IP / PSC only). Read-only gcloud calls against the active project (gcloud config set project, or CLOUDSDK_CORE_PROJECT); credentials come from the SDK's normal configuration (gcloud auth login, a service account or ADC). A missing CLI, credential or disabled API fails the check.

점검 방법

감사 방식: 셸 명령

shell

out=$(gcloud sql instances list --format='value(name,settings.ipConfiguration.ipv4Enabled)' 2>/dev/null) || exit 1
printf '%s\n' "$out" | awk -F '\t' 'NF && $2 == "True" { n++; print "public IP: " $1 } END { if (!n) print "compliant" }'

예상 출력: compliant

조치 방법

조치 방식: 가이드 또는 인프라 패치

Configure private IP (gcloud sql instances patch <instance> --network=<vpc> ...) then gcloud sql instances patch <instance> --no-assign-ip. Enforce with constraints/sql.restrictPublicIp.
