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 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。

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，请参考创建自定义策略。
如何使用这些元素编辑SCP自定义策略，请参考创建SCP。

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GeminiDB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GeminiDB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GeminiDB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。

GeminiDB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3 GeminiDB支持的资源类型
资源类型	URN
instance	geminidb:<region>:<account-id>:instance:<instance-id>

条件（Condition）

条件键概述

条件（Condition）是身份策略生效的特定条件，包括条件键和运算符。

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。
- 服务级条件键（前缀通常为服务缩写，如geminidb:）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。

GeminiDB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身份策略语句应用的条件。

表4 GeminiDB支持的服务级条件键
服务级条件键	类型	单值/多值	说明
gaussdbfornosql:AssociatePublicIp	boolean	单值	按照请求参数中传递的是否绑定EIP策略标签键筛选访问权限。
gaussdbfornosql:VpcId	string	单值	按照请求参数中传递的虚拟私有云主键标签键筛选访问权限。
gaussdbfornosql:Subnet	string	单值	按照请求参数中传递的子网标签键筛选访问权限。

条件键示例

gaussdbfornosql:AssociatePublicIp

示例：表示禁止GeminiDB实例绑定EIP。

{
  "Version": "5.0",
  "Statement": [
    {
      "Effect": "Deny",
      "Action": [
        "gaussdbfornosql:instance:updateEIP"
      ],
      "Condition": {
        "Bool": {
          "gaussdbfornosql:AssociatePublicIp": [
            "true"
          ]
        }
      }
    }
  ]
}

gaussdbfornosql:VpcId

示例：表示允许指定VPC创建实例。

{
  "Version": "5.0",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "gaussdbfornosql:instance:create"
      ],
      "Condition": {
        "StringEquals": {
          "gaussdbfornosql:VpcId": [
            "f457aa28-72de-42b8-8517-d9c6e14b9d09"
          ]
        }
      }
    }
  ]
}

gaussdbfornosql:Subnet

示例：表示允许指定子网创建实例。

{
  "Version": "5.0",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "gaussdbfornosql:instance:create"
      ],
      "Condition": {
        "StringEquals": {
          "gaussdbfornosql:Subnet": [
            "c0650bbe-4c89-4f2a-8cd2-3e2171b96d99"
          ]
        }
      }
    }
  ]
}
