Ensure Cloud SQL instances require all incoming connections to use SSL

高等級 1自動化gcp

說明

Without enforced TLS, database credentials and data can cross the network unencrypted. Every instance must have requireSsl true or sslMode ENCRYPTED_ONLY / TRUSTED_CLIENT_CERTIFICATE_REQUIRED. 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.

檢查方式

稽核方法: Shell 指令

shell

out=$(gcloud sql instances list --format='value(name,settings.ipConfiguration.requireSsl,settings.ipConfiguration.sslMode)' 2>/dev/null) || exit 1
printf '%s\n' "$out" | awk -F '\t' 'NF && $2 != "True" && $3 != "ENCRYPTED_ONLY" && $3 != "TRUSTED_CLIENT_CERTIFICATE_REQUIRED" { n++; print "SSL not required: " $1 } END { if (!n) print "compliant" }'

預期輸出: compliant

修補方式

修補方法: 操作指南或基礎設施修補檔

gcloud sql instances patch <instance> --ssl-mode=ENCRYPTED_ONLY (or TRUSTED_CLIENT_CERTIFICATE_REQUIRED). Update clients to connect with TLS or via the Cloud SQL Auth Proxy first.
