设置 Amazon IoT Events 警报权限
当您使用 Amazon IoT Events 警报模型监控 Amazon IoT SiteWise 资产属性时，您必须拥有以下 IAM 权限：
-
允许 Amazon IoT Events 向发送数据的 Amazon IoT Events 服务角色 Amazon IoT SiteWise。有关更多信息，请参阅 Amazon IoT Events 开发人员指南中的适用于 Amazon IoT Events的 身份和访问管理。
-
您必须拥有以下 Amazon IoT SiteWise 操作权限：
iotsitewise:DescribeAssetModel和iotsitewise:UpdateAssetModelPropertyRouting。这些权限允许 Amazon IoT SiteWise 向 Amazon IoT Events 警报模型发送资产属性值。
有关更多信息，请参阅 IAM 用户指南的基于资源的策略。
所需的操作权限
管理员可以使用 Amazon JSON 策略来指定谁有权访问什么。也就是说，哪个主体 可以对什么资源 执行操作，以及在什么 条件 下执行。JSON 策略的 Action 元素描述可用于在策略中允许或拒绝访问的操作。
在定义 Amazon IoT Events 警报模型之前，必须授予以下权限，允许 Amazon IoT SiteWise 向警报模型发送资产属性值。
-
iotsitewise:DescribeAssetModel— Amazon IoT Events 允许检查资产属性是否存在。 -
iotsitewise:UpdateAssetModelPropertyRouting— Amazon IoT SiteWise 允许自动创建允许 Amazon IoT SiteWise 向其发送数据的订阅 Amazon IoT Events。
有关 Amazon IoT SiteWise 支持的操作的更多信息，请参阅《服务授权参考》 Amazon IoT SiteWise中定义的操作。
例 权限策略示例 1
以下策略允许 Amazon IoT SiteWise 向任何 Amazon IoT Events 警报模型发送资产属性值。
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iotevents:CreateAlarmModel", "iotevents:UpdateAlarmModel" ], "Resource": "arn:aws:iotevents:us-east-1:123456789012:alarmModel/*" }, { "Effect": "Allow", "Action": [ "iotsitewise:DescribeAssetModel", "iotsitewise:UpdateAssetModelPropertyRouting" ], "Resource": "arn:aws:iotsitewise:us-east-1:123456789012:asset-model/*" } ] }
例 权限策略示例 2
以下策略 Amazon IoT SiteWise 允许将指定资产属性的值发送到指定的 Amazon IoT Events 警报模型。
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iotevents:CreateAlarmModel", "iotevents:UpdateAlarmModel" ], "Resource": "arn:aws:iotevents:us-east-1:123456789012:alarmModel/*" }, { "Effect": "Allow", "Action": [ "iotsitewise:DescribeAssetModel" ], "Resource": "arn:aws:iotsitewise:us-east-1:123456789012:asset-model/*" }, { "Effect": "Allow", "Action": [ "iotsitewise:UpdateAssetModelPropertyRouting" ], "Resource": [ "arn:aws:iotsitewise:us-east-1:123456789012:asset-model/12345678-90ab-cdef-1234-567890abcdef" ], "Condition": { "StringLike": { "iotsitewise:propertyId": "abcdef12-3456-7890-abcd-ef1234567890", "iotevents:alarmModelArn": "arn:aws:iotevents:us-east-1:123456789012:alarmModel/MyAlarmModel" } } } ] }
（可选） ListInputRoutings 权限
更新或删除资产模型时， Amazon IoT SiteWise 可以检查中的警报模型是否 Amazon IoT Events 正在监视与该资产模型关联的资产属性。这可以防止您删除 Amazon IoT Events 警报当前正在使用的资产属性。要在中启用此功能 Amazon IoT SiteWise，您必须拥有iotevents:ListInputRoutings权限。此权限 Amazon IoT SiteWise 允许调用支持的 ListInputRouting s API 操作。 Amazon IoT Events
注意
强烈建议您添加 ListInputRoutings 权限。
例 权限策略示例
以下政策允许您更新和删除资产模型，并使用中的 ListInputRoutings API Amazon IoT SiteWise。
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iotsitewise:UpdateAssetModel", "iotsitewise:DeleteAssetModel", "iotevents:ListInputRoutings" ], "Resource": "arn:aws:iotsitewise:us-east-1:123456789012:asset-model/*" } ] }
SiteWise 监控器所需的权限
如果要在 SiteWise 监控门户中使用警报功能，则必须使用以下策略更新SiteWise 监控服务角色：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iotsitewise:DescribePortal", "iotsitewise:CreateProject", "iotsitewise:DescribeProject", "iotsitewise:UpdateProject", "iotsitewise:DeleteProject", "iotsitewise:ListProjects", "iotsitewise:BatchAssociateProjectAssets", "iotsitewise:BatchDisassociateProjectAssets", "iotsitewise:ListProjectAssets", "iotsitewise:CreateDashboard", "iotsitewise:DescribeDashboard", "iotsitewise:UpdateDashboard", "iotsitewise:DeleteDashboard", "iotsitewise:ListDashboards", "iotsitewise:CreateAccessPolicy", "iotsitewise:DescribeAccessPolicy", "iotsitewise:UpdateAccessPolicy", "iotsitewise:DeleteAccessPolicy", "iotsitewise:ListAccessPolicies", "iotsitewise:DescribeAsset", "iotsitewise:ListAssets", "iotsitewise:ListAssociatedAssets", "iotsitewise:DescribeAssetProperty", "iotsitewise:GetAssetPropertyValue", "iotsitewise:GetAssetPropertyValueHistory", "iotsitewise:GetAssetPropertyAggregates", "iotsitewise:BatchPutAssetPropertyValue", "iotsitewise:ListAssetRelationships", "iotsitewise:DescribeAssetModel", "iotsitewise:ListAssetModels", "iotsitewise:UpdateAssetModel", "iotsitewise:UpdateAssetModelPropertyRouting", "sso-directory:DescribeUsers", "sso-directory:DescribeUser", "iotevents:DescribeAlarmModel", "iotevents:ListTagsForResource" ], "Resource": "*" }, { "Effect": "Allow", "Action": [ "iotevents:BatchAcknowledgeAlarm", "iotevents:BatchSnoozeAlarm", "iotevents:BatchEnableAlarm", "iotevents:BatchDisableAlarm" ], "Resource": "*", "Condition": { "Null": { "iotevents:keyValue": "false" } } }, { "Effect": "Allow", "Action": [ "iotevents:CreateAlarmModel", "iotevents:TagResource" ], "Resource": "*", "Condition": { "Null": { "aws:RequestTag/iotsitewisemonitor": "false" } } }, { "Effect": "Allow", "Action": [ "iotevents:UpdateAlarmModel", "iotevents:DeleteAlarmModel" ], "Resource": "*", "Condition": { "Null": { "aws:ResourceTag/iotsitewisemonitor": "false" } } }, { "Effect": "Allow", "Action": [ "iam:PassRole" ], "Resource": "*", "Condition": { "StringEquals": { "iam:PassedToService": [ "iotevents.amazonaws.com" ] } } } ] }
