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服务中的服务控制策略（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。
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）。
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AAD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AAD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。
您可以在身份策略语句的Action元素中指定以下AAD的相关操作。

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。
AAD定义了以下可以在自定义身份策略的Resource元素中使用的资源类型。
资源类型 | URN |
|---|---|
forwardingRule | aad::<account-id>:forwardingRule:<forwarding-rule-id> |
package | aad::<account-id>:package:<package-id> |
policy | aad::<account-id>:policy:<policy-id> |
alarmConfig | aad::<account-id>:alarmConfig:<alarm-config-id> |
domain | aad::<account-id>:domain:<domain-id> |
certificate | aad::<account-id>:certificate:<certificate-id> |
instance | aad::<account-id>:instance:<instance-id> |
whiteBlackIpRule | aad::<account-id>:whiteBlackIpRule:<white-black-ip-rule-id> |
