# スキャン対象のAWSリージョンを制御

Aikido によるスキャン対象から特定のリージョンを除外したい場合は、Aikido IAM ロールに付与された IAM ポリシーを調整できます。以下の例を参照し、AWS アカウント ID とリージョンをシナリオに合わせて調整してください：

### ECR コンテナスキャン

#### 特定のリージョンのイメージのみをスキャンする

{% hint style="info" %}
標準ポリシーでは、すべてのリージョンの ECR リポジトリへのアクセスが許可されます。この例ではアクセスを `us-east-2` に設定し、 `eu-west-1`。なお、 `ecr:GetAuthorizationToken` は、引き続きすべてのリージョンで許可されている必要があります。
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.aikido.dev/docs/docs-ja/kuraudosukyan/connect-your-cloud/aws/connect-aws-account-to-aikido/control-which-aws-regions-are-scanned.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
