# Amazon EMR 完整存取的 IAM 受管政策 (v2 受管預設政策）
<a name="emr-managed-policy-fullaccess-v2"></a>

v2 範圍的 EMR 預設受管政策會授予使用者特定的存取權限。它們需要預先定義的 Amazon EMR 資源標籤和 Amazon EMR 使用的資源的 `iam:PassRole` 條件金鑰，例如用於啟動叢集的 `Subnet` 和 `SecurityGroup`。

若要授予 Amazon EMR 範圍內所需的動作，請附接 `AmazonEMRFullAccessPolicy_v2` 受管政策。此更新的預設受管政策會取代 [`AmazonElasticMapReduceFullAccess`](emr-managed-policy-fullaccess.md) 受管政策。

`AmazonEMRFullAccessPolicy_v2` 取決於 Amazon EMR 佈建或使用的資源的範圍縮小存取權。使用此政策時，您需要在佈建叢集時傳遞使用者標籤 `for-use-with-amazon-emr-managed-policies = true`。Amazon EMR 將自動傳播此標籤。此外，您可能還需要手動將使用者標籤新增至特定類型的資源，例如非 Amazon EMR 建立的 EC2 安全群組。如需詳細資訊，請參閱[標記資源以使用受管政策](emr-managed-iam-policies.md#manually-tagged-resources)。

[https://console.aws.amazon.com/iam/home#policies/arn:aws:iam::aws:policy/AmazonEMRFullAccessPolicy_v2](https://console.aws.amazon.com/iam/home#policies/arn:aws:iam::aws:policy/AmazonEMRFullAccessPolicy_v2) 政策透過執行下列操作來保護資源：
+ 需要使用預先定義的 Amazon EMR 受管政策標籤 `for-use-with-amazon-emr-managed-policies` 來標記資源，才能建立叢集和存取 Amazon EMR。
+ 將 `iam:PassRole` 動作限制為特定預設角色和對特定服務的 `iam:PassedToService` 存取。
+ 依預設不再提供對 Amazon EC2、Amazon S3 及其他服務的存取。

以下是此政策的內容。
