# AWS 的托管策略 AWS IoT SiteWise
<a name="security-iam-awsmanpol"></a>

使用 AWS 托管策略简化向用户、群组和角色添加权限的过程，而不是自己编写策略。创建为团队提供确切权限的 [IAM 客户管理型策略](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_create-console.html)需要时间和专业知识。为了更快地进行设置，可以考虑将我们的 AWS 托管策略用于常见用例。在您的 AWS 账户中查找 AWS 托管政策。有关 AWS 托管式策略的更多信息，请参阅《IAM 用户指南》**中的 [AWS 托管式策略](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_managed-vs-inline.html#aws-managed-policies)。

AWS 服务负责更新和维护 AWS 托管策略，这意味着您无法修改这些策略的权限。有时， AWS IoT SiteWise 可能会添加权限以适应新功能，从而影响附加策略的所有身份。新服务或特征的推出往往伴随着此类更新。但是，权限永远不会被移除，这就可以确保您的设置保持不变。

此外，还 AWS 支持跨多个服务的工作职能的托管策略。例如，**ReadOnlyAccess** AWS 托管策略提供对所有 AWS 服务和资源的只读访问权限。当服务启动一项新功能时， AWS 会为新操作和资源添加只读权限。有关工作职能策略的列表和说明，请参阅 *IAM 用户指南*中的[适用于工作职能的AWS 托管策略](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_job-functions.html)。

## AWS 托管策略： AWSIoTSiteWiseReadOnlyAccess
<a name="security-iam-awsmanpol-AWSIoTSiteWiseReadOnlyAccess"></a>

使用`AWSIoTSiteWiseReadOnlyAccess` AWS 托管策略允许对进行只读访问 AWS IoT SiteWise。

您可以将 `AWSIoTSiteWiseReadOnlyAccess` 策略附加到 IAM 身份。

**服务级别权限**

此策略提供对的只读访问权限 AWS IoT SiteWise，包括执行只读 SQL 查询的权限。此策略中不包含其他服务权限。
