# スキャンするAWSリージョンを制御する

このページでは、CSPM、ECR、EC2スキャンの対象となるAWSリージョンを制限するためのガイドラインを提供します。

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 の IAM ロールに関連付けられた 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応じて調整してください:

### ECR コンテナスキャン

#### 特定のリージョンからのみイメージをスキャンする

{% 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` および `eu-west-1`に制限します。なお、 `ecr:GetAuthorizationToken` は引き続きすべてのリージョンに対して付与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.
