# 身份策略授权参考 云服务在IAM预置了常用授权项，称为系统身份策略。如果IAM系统身份策略无法满足授权要求，管理员可以根据各服务支持的授权项，创建IAM自定义身份策略来进行精细的访问控制，IAM自定义身份策略是对系统身份策略的扩展和补充。 除IAM服务外，[Organizations](https://support.huaweicloud.com/productdesc-organizations/org_01_0011.html)服务中的[服务控制策略](https://support.huaweicloud.com/usermanual-organizations/org_03_0065.html)（Service Control Policies，以下简称SCP）也可以使用这些授权项元素设置访问控制策略。 SCP不直接进行授权，只划定权限边界。将SCP绑定到组织单元或者成员账号时，并没有直接对组织单元或成员账号授予操作权限，而是规定了成员账号或组织单元包含的成员账号的授权范围。IAM身份策略授予权限的有效性受SCP限制，只有在SCP允许范围内的权限才能生效。 IAM服务与Organizations服务在使用这些元素进行访问控制时，存在着一些区别，详情请参见：[IAM服务与Organizations服务权限访问控制的区别](https://support.huaweicloud.com/organizations_faq/org_06_0004.html)。 本章节介绍IAM服务身份策略授权场景中自定义身份策略和组织服务中SCP使用的元素，这些元素包含了操作（Action）、资源（Resource）和条件（Condition）。 - 如何使用这些元素编辑IAM自定义身份策略，请参考[创建自定义身份策略](https://support.huaweicloud.com/usermanual-iam5/iam_01_0917.html)。 - 如何使用这些元素编辑SCP自定义策略，请参考[创建SCP](https://support.huaweicloud.com/usermanual-organizations/org_03_0035.html)。 #### 操作（Action） 操作（Action）即为身份策略中支持的授权项。 - **"** **访问级别** **"**列描述如何对操作进行分类（List、Read和Write等）。此分类可帮助您了解在身份策略中相应操作对应的访问级别。 - **"资源类型"** 列指每个操作是否支持资源级权限。 - 资源类型支持通配符号\*表示所有。如果此列没有值（-），则必须在身份策略语句的Resource元素中指定所有资源类型（"\*"）。 - 如果该列包含资源类型，则必须在具有该操作的语句中指定该资源的URN。 - 资源类型列中必需资源在表中用星号（\*）标识，表示使用此操作必须指定该资源类型。 关于ECS定义的资源类型的详细信息请参见[资源类型（Resource）]。 - **"条件键"** 列包括了可以在身份策略语句的Condition元素中支持指定的键值。 - 如果该授权项资源类型列存在值，则表示条件键仅对列举的资源类型生效。 - 如果该授权项资源类型列没有值（-），则表示条件键对整个授权项生效。 - 如果此列条件键没有值（-），表示此操作不支持指定条件键。 关于ECS定义的条件键的详细信息请参见[条件（Condition）]。 - **"别名"** 列包括了可以在身份策略中配置的策略授权项。通过这些授权项，可以控制支持策略授权的API访问。详细信息请参见[身份策略兼容性说明](https://support.huaweicloud.com/iam5_faq/iam_01_1103.html)。 您可以在身份策略语句的Action元素中指定以下ECS的相关操作。 表1ECS支持的授权项 | 授权项 | 描述 | 访问级别 | 资源类型（\*为必须） | 条件键 | 别名 | |:---|:---|:---|:---|:---|:---| | ecs:cloudServers:createServers | 授予创建ECS云服务器的权限。 | write | -

| #### 资源类型（Resource） 资源类型（Resource）表示身份策略所作用的资源。如[表3]中的某些操作指定了可以在该操作指定的资源类型，则必须在具有该操作的身份策略语句中指定该资源的URN，身份策略仅作用于此资源；如未指定，Resource默认为"\*"，则身份策略将应用到所有资源。您也可以在身份策略中设置条件，从而指定资源类型。 ECS定义了以下可以在身份策略的Resource元素中使用的资源类型。 表3ECS支持的资源类型 | 资源类型 | URN | |:---|:---| | instance | ecs:\:\:instance:\ | #### 条件（Condition） **条件键概述** 条件键（Condition）是身份策略生效的特定条件，包括[条件键](https://support.huaweicloud.com/usermanual-iam5/iam_01_0934.html)和[运算符](https://support.huaweicloud.com/usermanual-iam5/iam_01_0934.html)。 - 条件键表示身份策略语句的Condition元素中的键值。根据适用范围，分为全局级条件键和服务级条件键。 - 全局级条件键（前缀为g:）适用于所有操作，在鉴权过程中，云服务不需要提供用户身份信息，系统将自动获取并鉴权。详情请参见：[全局条件键](https://support.huaweicloud.com/usermanual-iam5/iam_01_0934.html)。 - 服务级条件键（前缀通常为服务缩写，如ecs:）仅适用于对应服务的操作，详情请参见[表4]。 - 单值/多值表示API调用时请求中与条件关联的值数。单值条件键在API调用时的请求中最多包含一个值，多值条件键在API调用时请求可以包含多个值。例如：g:SourceVpce是单值条件键，表示仅允许通过某个VPC终端节点发起请求访问某资源，一个请求最多包含一个VPC终端节点ID值。g:TagKeys是多值条件键，表示请求中携带的所有标签的key组成的列表，当用户在调用API请求时传入标签可以传入多个值。 - 运算符与条件键、条件值一起构成完整的条件判断语句，当请求信息满足该条件时，身份策略才能生效。支持的运算符请参见：[运算符](https://support.huaweicloud.com/usermanual-iam5/iam_01_0934.html)。 **ECS支持的服务级条件键** ECS定义了以下可以在身份策略的Condition元素中使用的条件键，您可以使用这些条件键进一步细化策略语句应用的条件。 表4ECS支持的服务级条件键 | 服务级条件键 | 类型 | 单值/多值 | 说明 | |:---|:---|:---|:---| | ecs:imageID | string | 多值 | 根据请求参数中指定的镜像ID过滤访问。 | | ecs:FlavorId | string | 多值 | 根据请求参数中指定的规格ID过滤访问。 | | ecs:VpcId | string | 多值 | 根据请求参数中指定的网络ID过滤访问。 | | ecs:SubnetId | string | 多值 | 根据请求参数中指定的子网ID过滤访问。 | | ecs:KmsKeyId | string | 多值 | 根据请求参数中指定的加密密钥ID过滤访问。 | | ecs:ServerId | string | 单值 | 根据云服务器ID过滤访问。 | | ecs:SSHKeyPairName | string | 单值 | 根据请求参数中指定的SSH密钥对的名称过滤访问。 | | ecs:AvailabilityZone | string | 单值 | 根据请求参数中指定的可用区名称过滤访问。 | | ecs:PortId | string | 多值 | 根据请求参数中指定的portId过滤访问。 | | ecs:SupportAgentType | string | 多值 | 根据请求中指定的agent类型过滤访问。 | | ecs:ImageSupportAgentType | string | 多值 | 根据请求中指定的镜像支持的agent类型过滤访问。 | | ecs:VolumeId | string | 单值 | 根据请求中指定的卷ID过滤访问。 | | ecs:ImageType | string | 单值 | 根据请求中指定镜像的类型过滤访问（如：公共镜像、私有镜像、共享镜像、市场镜像）。 | | ecs:OsType | string | 单值 | 根据请求中指定镜像的操作系统类型过滤访问（如：Linux、Windows）。 | | ecs:OsVersion | string | 单值 | 根据请求中指定镜像的操作系统版本过滤访问（如：CentOS 7.3 64bit）。 | | ecs:ImagePlatform | string | 单值 | 根据请求中指定镜像的平台过滤访问（如：Windows、Ubuntu、Red Hat、SUSE、CentOS）。 | | ecs:LegacyAPIFlavor | string | 单值 | 根据请求的API类型过滤访问（当前仅支持OpenStackNative）。 |
