资源级权限指的是能够指定用户对哪些资源具有执行操作的能力。云服务器（Cloud Virtual Machine，CVM）部分支持资源级权限，即表示针对支持资源级权限的 CVM 操作，控制何时允许用户执行操作或是允许用户使用的特定资源。例如，您 授权用户拥有广州地域的 CVM 操作权限。
在访问管理（Cloud Access Management，CAM）中可授权的资源类型如下：
| 资源类型 | 授权策略中的资源描述方法 |
| 云服务器实例相关 | qcs::cvm:$region::instance/* |
| 云服务器密钥相关 | qcs::cvm:$region::keypair/* |
| 云服务器镜像相关 | qcs::cvm:$region:$account:image/* |
云服务器实例相关、云服务器密钥相关 和 云服务器镜像相关 分别介绍了当前支持资源级权限的 CVM API 操作，以及每个操作支持的资源和条件密钥。设置资源路径时，您需要将$region、$account等变量参数修改为您实际的参数信息，同时您也可以在路径中使用 * 通配符。相关操作示例可参见 访问管理示例。注意表中未列出的 CVM API 操作即表示该 CVM API 操作不支持资源级权限。针对不支持资源级权限的 CVM API 操作，您仍可以向用户授予使用该操作的权限，但是策略语句的资源元素必须指定为 *。
