[アップデート] AWS Config の適合パックに「CIS コンプライアンスパック」および「AWS Control Tower Detective Guardrails」2 つのテンプレートが追加されました

適合パックに「CIS ベンチマーク」および「AWS Control Tower」向けの 2 つのテンプレートが追加されました。CIS ベンチマークの Config ルールって Security Hub と被ってません、、？

この記事は公開されてから1年以上経過しています。情報が古い可能性がありますので、ご注意ください。

先日のアップデートで AWS Config の適合パック（コンフォーマンスパック）に以下 2 つのテンプレートが追加されました。

CISコンプライアンスパックテンプレート
- CIS 要件への準拠を検証するのに役立ちます。ただし、すべての CIS 要件すべてをカバーするものではありません。Config ルールを使用してカバーできる要件のみであることに注意してください。
AWS Control Tower Detective Guardrails Conformance Pack
- AWS Control Tower の AWS Config ルールベースのガードレールがすべて含まれています。この適合パックを使用して、AWS Control Tower に登録する前に AWS Control Tower 検出ガードレールを既存のアカウントに適用するか、現在 AWS Control Tower でサポートされていないリージョンのアカウントのリソースを管理することもできます。

何がうれしいのか

適合パックとは？

適合パックは AWS Config ルールと修復アクションの集まりであり、アカウントやリージョン、または AWS Organizations の組織全体に 1 つのエンティティとして簡単にデプロイできます。

CloudFormation でデプロイされるのでカスタマイズが可能

今回リリースされた「CIS コンプライアンスパックテンプレート」を例にすると、CIS ベンチマーク向けの AWS Config ルールであれば AWS Security Hub の「CIS AWS Foundations Benchmark v1.2.0」を有効にしたら良いのでは？　と思いますよね。私も思いました。

社内のメンバーに「これって、Security Hub でえぇんちゃうの？」て聞いたところ、Security Hub の場合、ルールはフルマネージドであるため個別調整できるのは有効か無効の二択のみ。

一方、適合パックの場合はカスタマイズが可能なので、スコープのチューニングなどの個別調整がきく点がメリット、とのことです。なるほど！

あと、Security Hub や Control Tower が利用できないリージョンの場合、この適合パックで代用することも可能ですね。

やってみる

それでは、さっそくやってみましょう。

手順

適合パックをデプロイするまでの手順は、以下の 3 ステップ。

Service-Linked Roleの作成
テンプレート配置用のS3バケットの作成およびバケットポリシーの作成
適合パックのデプロイ

Service-Linked Role の作成

Service-Linked Role の作成は、公式ガイドに従い、AWS CLI で作成します。

$ aws iam create-service-linked-role --aws-service-name config-conforms.amazonaws.com \
    --description "my service linked role for config-conforms"
    
Role:
  Arn: arn:aws:iam::xxxxxxxxxxxx:role/aws-service-role/config-conforms.amazonaws.com/AWSServiceRoleForConfigConforms
  AssumeRolePolicyDocument:
    Statement:
    - Action:
      - sts:AssumeRole
      Effect: Allow
      Principal:
        Service:
        - config-conforms.amazonaws.com
    Version: '2012-10-17'
  CreateDate: '2020-04-30T08:52:00+00:00'
  Path: /aws-service-role/config-conforms.amazonaws.com/
  RoleId: AROAXXXXXXXXXXXXXXXXX
  RoleName: AWSServiceRoleForConfigConforms

テンプレート配置用のS3バケットの作成およびバケットポリシーの作成

次に、テンプレートを配置するための S3 バケットを作成し、先程の Service-Linked Role がアクセスできるようにバケットポリシーを記載します。<AccountId>, <delivery-bucket-name>, <[optional] prefix> は環境によって読み替えてください。

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "AWSConfigConformsBucketPermissionsCheck",
      "Effect": "Allow",
      "Principal": {
        "AWS": [
            "arn:aws:iam::<AccountId>:role/aws-service-role/config-conforms.amazonaws.com/AWSServiceRoleForConfigConforms"
        ]
      },
      "Action": "s3:GetBucketAcl",
      "Resource": "arn:aws:s3:::<delivery-bucket-name>"
    },
    {
      "Sid": "AWSConfigConformsBucketDelivery",
      "Effect": "Allow",
      "Principal": {
        "AWS": [
            "arn:aws:iam::<AccountId>:role/aws-service-role/config-conforms.amazonaws.com/AWSServiceRoleForConfigConforms"
        ]
      },
      "Action": "s3:PutObject",
      "Resource": "arn:aws:s3:::<delivery-bucket-name>/<[optional] prefix>/AWSLogs/<AccountId>/Config/*",
      "Condition": {
        "StringEquals": {
          "s3:x-amz-acl": "bucket-owner-full-control"
        }
      }
    },
    {
      "Sid": " AWSConfigConformsBucketReadAccess",
      "Effect": "Allow",
      "Principal": {
        "AWS": [
            "arn:aws:iam::<AccountId>:role/aws-service-role/config-conforms.amazonaws.com/AWSServiceRoleForConfigConforms"
        ]
      },
      "Action": "s3:GetObject",
      "Resource": "arn:aws:s3:::<delivery-bucket-name>/<[optional] prefix>/AWSLogs/<AccountId>/Config/*"
    }
  ]
}

AWS Config 管理コンソールを開き、[適合パックをデプロイ] をクリックします。

[サンプルテンプレートを使用] を選択し、サンプルテンプレートをプルダウンメニューから選びます。AWS Control Tower Detective Guardrails および Operational Best Practices for CIS が追加されていますね。

今回は Operational Best Practices for CIS を試してみましょう。

任意の適合パック名を入力し、先程、作成した S3 バケットを選択し、次へ。

内容を確認し、[適合パックをデプロイ]をクリックします。

しばらく待つとデプロイが完了します。

確認

デプロイされた適合パックを確認してみると、以下のようなルールとなっていました。修復アクションは組み込まれていないようですね。

サンプルテンプレート

テンプレートは yaml で記述された CloudFormation です。サンプルテンプレートをもとに個別カスタマイズしてデプロイすることも可能です。
