Ensure automatic rotation is enabled for customer created symmetric KMS keys

SedangLevel 2Otomatisalibaba

Deskripsi

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.

Cara pemeriksaan

Metode audit: Perintah shell

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

Output yang diharapkan: compliant

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

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