# 弹性负载均衡 ELB 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 Policy，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ELB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ELB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ELB的相关操作。 表1ELB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 | |:---|:---|:---|:---|:---|:---| | elb:flavors:show | 授予查询指定规格的详情。 | Read | flavor \* | -

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elb:）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)。 **ELB支持的服务级条件键** ELB定义了以下可以在自定义身份策略的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身份策略语句应用的条件。 表4ELB支持的服务级条件键 | 服务级条件键 | 类型 | 单值/多值 | 说明 | |:---|:---|:---|:---| | elb:AssociatePublicips | boolean | 单值 | 根据创建或修改负载均衡器时是否涉及创建或绑定公网操作筛选访问权限。若要完全限制弹性负载均衡器的公网访问，则需要同时使用弹性公网IP的相关Action进行策略管理。 | | elb:UpdateListenerIpgroup | boolean | 单值 | 根据修改监听器时是否涉及更新访问控制筛选访问权限。 | | elb:OnlyUpdateListenerIpgroup | boolean | 单值 | 根据修改监听器时是否仅涉及更新访问控制筛选访问权限。 |
