Ensure automatic rotation is enabled for customer created symmetric KMS keys

中等級 2自動化alibaba

說明

Automatic rotation limits the amount of data protected by one key version. In the profile's region, every Enabled symmetric (Aliyun_AES_256 / Aliyun_SM4) key created by the account must have AutomaticRotation Enabled; service-created default keys are skipped. Read-only aliyun CLI calls; credentials and default region come from the CLI's normal profile (aliyun configure, ~/.aliyun/config.json or ALIBABA_CLOUD_* environment variables). JSON output is parsed with grep/sed/awk. A missing CLI or credential fails the check.

檢查方式

稽核方法: Shell 指令

shell

out=$(aliyun kms ListKeys --PageSize 100 2>/dev/null) || exit 1
keys=$(printf '%s\n' "$out" | sed -n 's/.*"KeyId"[[:space:]]*:[[:space:]]*"\([^"]*\)".*/\1/p')
get() { printf '%s\n' "$m" | sed -n "s/.*\"$1\"[[:space:]]*:[[:space:]]*\"\([^\"]*\)\".*/\1/p" | head -n 1; }
bad=0
for k in $keys; do
  m=$(aliyun kms DescribeKey --KeyId "$k" 2>/dev/null) || exit 1
  case "$(get KeySpec)" in ''|Aliyun_AES_256|Aliyun_SM4) ;; *) continue ;; esac
  [ "$(get KeyState)" = Enabled ] || continue
  case "$(get Creator)" in ''|*[!0-9]*) continue ;; esac
  [ "$(get AutomaticRotation)" = Enabled ] || { echo "rotation off: $k"; bad=1; }
done
[ "$bad" -eq 0 ] && echo 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

aliyun kms UpdateRotationPolicy --KeyId <key-id> --EnableAutomaticRotation true --RotationInterval 31536000s (or a shorter interval) for each listed key.
