证书策略示例
对于在注册 Amazon IoT Core 表中注册的设备，以下策略授予 Amazon IoT Core 使用与事物名称匹配的客户端 ID 进行连接的权限，以及向名称等于该设备用于进行自我身份验证certificateId的证书的主题发布的权限：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Publish" ], "Resource": ["arn:aws:iot:us-east-1:123456789012:topic/${iot:CertificateId}"] }, { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": ["arn:aws:iot:us-east-1:123456789012:client/${iot:Connection.Thing.ThingName}"] } ] }
对于未在注册 Amazon IoT Core 表中注册的设备，以下策略授予 Amazon IoT Core 使用客户端 ID、client1client2、client3和进行连接的权限，以及发布到名称等于设备用于进行自我身份验证certificateId的证书的主题的权限：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Publish" ], "Resource": ["arn:aws:iot:us-east-1:123456789012:topic/${iot:CertificateId}"] }, { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": [ "arn:aws:iot:us-east-1:123456789012:client/client1", "arn:aws:iot:us-east-1:123456789012:client/client2", "arn:aws:iot:us-east-1:123456789012:client/client3" ] } ] }
对于在注册 Amazon IoT Core 表中注册的设备，以下策略授予 Amazon IoT Core 使用与事物名称匹配的客户端 ID 进行连接的权限，以及向名称等于该设备进行身份验证的证书主题CommonName字段的主题发布权限：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Publish" ], "Resource": ["arn:aws:iot:us-east-1:123456789012:topic/${iot:Certificate.Subject.CommonName}"] }, { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": ["arn:aws:iot:us-east-1:123456789012:client/${iot:Connection.Thing.ThingName}"] } ] }
注意
在此示例中，证书的使用者公用名用作主题标识符，并假设使用者公用名对于每个已注册的证书都是唯一的。如果证书在多个设备之间共享，则共享此证书的所有设备的使用者公用名将相同，因而允许从多个设备向同一主题发布权限（不推荐）。
对于未在注册 Amazon IoT Core 表中注册的设备，以下策略授予 Amazon IoT Core 使用客户端 ID、client1client2、client3和进行连接的权限，以及向名称等于该设备用于进行身份验证的证书主题CommonName字段的主题发布的权限：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Publish" ], "Resource": ["arn:aws:iot:us-east-1:123456789012:topic/${iot:Certificate.Subject.CommonName}"] }, { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": [ "arn:aws:iot:us-east-1:123456789012:client/client1", "arn:aws:iot:us-east-1:123456789012:client/client2", "arn:aws:iot:us-east-1:123456789012:client/client3" ] } ] }
注意
在此示例中，证书的使用者公用名用作主题标识符，并假设使用者公用名对于每个已注册的证书都是唯一的。如果证书在多个设备之间共享，则共享此证书的所有设备的使用者公用名将相同，因而允许从多个设备向同一主题发布权限（不推荐）。
对于在注册 Amazon IoT Core 表中注册的设备，以下策略授予使用 Amazon IoT Core 与事物名称匹配的客户端 ID 进行连接的权限，以及在用于对设备进行身份验证的证书的Subject.CommonName.2字段设置为admin/时向名称前缀为的主题发布权限：Administrator
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": ["arn:aws:iot:us-east-1:123456789012:client/${iot:Connection.Thing.ThingName}"] }, { "Effect": "Allow", "Action": [ "iot:Publish" ], "Resource": ["arn:aws:iot:us-east-1:123456789012:topic/admin/*"], "Condition": { "StringEquals": { "iot:Certificate.Subject.CommonName.2": "Administrator" } } } ] }
对于未在注册 Amazon IoT Core 表中注册的设备，当用于对设备进行身份验证的证书的Subject.CommonName.2字段设置为admin/时client1，client2以下策略授予使用客户端 ID 连接client3和发布到名称前缀为的主题的权限： Amazon IoT Core Administrator
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": [ "arn:aws:iot:us-east-1:123456789012:client/client1", "arn:aws:iot:us-east-1:123456789012:client/client2", "arn:aws:iot:us-east-1:123456789012:client/client3" ] }, { "Effect": "Allow", "Action": [ "iot:Publish" ], "Resource": ["arn:aws:iot:us-east-1:123456789012:topic/admin/*"], "Condition": { "StringEquals": { "iot:Certificate.Subject.CommonName.2": "Administrator" } } } ] }
对于在注册 Amazon IoT Core 表中注册的设备，以下策略允许设备使用其事物名称发布特定主题，该主题包括用于对设备进行身份验证的证书ThingName何时将其任何一个Subject.CommonName字段设置为Administrator：admin/
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": ["arn:aws:iot:us-east-1:123456789012:client/${iot:Connection.Thing.ThingName}"] }, { "Effect": "Allow", "Action": [ "iot:Publish" ], "Resource": ["arn:aws:iot:us-east-1:123456789012:topic/admin/${iot:Connection.Thing.ThingName}"], "Condition": { "ForAnyValue:StringEquals": { "iot:Certificate.Subject.CommonName.List": "Administrator" } } } ] }
对于未在注册 Amazon IoT Core 表中注册的设备，当用于对设备进行身份验证的证书的任意一个Subject.CommonName字段设置为admin时client2，以下策略授予使用客户端 ID client1 连接client3和发布到主题的权限Administrator： Amazon IoT Core
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": [ "arn:aws:iot:us-east-1:123456789012:client/client1", "arn:aws:iot:us-east-1:123456789012:client/client2", "arn:aws:iot:us-east-1:123456789012:client/client3" ] }, { "Effect": "Allow", "Action": [ "iot:Publish" ], "Resource": ["arn:aws:iot:us-east-1:123456789012:topic/admin"], "Condition": { "ForAnyValue:StringEquals": { "iot:Certificate.Subject.CommonName.List": "Administrator" } } } ] }
