連接政策範例
下列政策拒絕用戶端 IDsclient1和 連線client2的許可 AWS IoT Core，同時允許裝置使用用戶端 ID 連線。用戶端 ID 符合在 AWS IoT Core 登錄檔中註冊並連接到用於連線之主體的物件名稱：
注意
對於已註冊的裝置，建議您使用 Connect 動作的物件政策變數，並將物件附加至用於連線的主體。
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Deny", "Action": [ "iot:Connect" ], "Resource": [ "arn:aws:iot:us-east-1:123456789012:client/client1", "arn:aws:iot:us-east-1:123456789012:client/client2" ] }, { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": [ "arn:aws:iot:us-east-1:123456789012:client/${iot:Connection.Thing.ThingName}" ], "Condition": { "Bool": { "iot:Connection.Thing.IsAttached": "true" } } } ] }
下列政策授予許可，以 AWS IoT Core 使用用戶端 ID 連線至 client1。此政策範例適用於未註冊的裝置。
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": [ "arn:aws:iot:us-east-1:123456789012:client/client1" ] } ] }
MQTT 持續工作階段政策範例
connectAttributes 可讓您在 IAM 政策中指定要在連線訊息中使用的屬性，例如 PersistentConnect 和 LastWill。如需詳細資訊，請參閱使用 connectAttributes。
下列政策允許與 PersistentConnect 功能連接：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": "arn:aws:iot:us-east-1:123456789012:client/client1", "Condition": { "ForAllValues:StringEquals": { "iot:ConnectAttributes": [ "PersistentConnect" ] } } } ] }
下列政策不允許 PersistentConnect，允許其他功能：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": "arn:aws:iot:us-east-1:123456789012:client/client1", "Condition": { "ForAllValues:StringNotEquals": { "iot:ConnectAttributes": [ "PersistentConnect" ] } } } ] }
上述政策也可以使用 StringEquals 表達，並允許任何其他功能，包括新功能：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": "arn:aws:iot:us-east-1:123456789012:client/client1", }, { "Effect": "Deny", "Action": [ "iot:Connect" ], "Resource": "*", "Condition": { "ForAnyValue:StringEquals": { "iot:ConnectAttributes": [ "PersistentConnect" ] } } } ] }
下列政策允許透過 PersistentConnect 和 LastWill 連接，但不允許任何其他新功能：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": "arn:aws:iot:us-east-1:123456789012:client/client1", "Condition": { "ForAllValues:StringEquals": { "iot:ConnectAttributes": [ "PersistentConnect", "LastWill" ] } } } ] }
下列政策允許透過具有或沒有 LastWill 的用戶端進行全新連接，但不允許任何其他功能：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": "arn:aws:iot:us-east-1:123456789012:client/client1", "Condition": { "ForAllValues:StringEquals": { "iot:ConnectAttributes": [ "LastWill" ] } } } ] }
下列政策只允許使用預設功能進行連接：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": "arn:aws:iot:us-east-1:123456789012:client/client1", "Condition": { "ForAllValues:StringEquals": { "iot:ConnectAttributes": [] } } } ] }
下列政策僅允許與 PersistentConnect 連接，而且只要連線使用 PersistentConnect，就允許任何新功能：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": "arn:aws:iot:us-east-1:123456789012:client/client1", "Condition": { "ForAnyValue:StringEquals": { "iot:ConnectAttributes": [ "PersistentConnect" ] } } } ] }
下列政策指出連接必須同時使用 PersistentConnect 和 LastWill，而且不允許任何新功能：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": "arn:aws:iot:us-east-1:123456789012:client/client1", "Condition": { "ForAllValues:StringEquals": { "iot:ConnectAttributes": [ "PersistentConnect", "LastWill" ] } } }, { "Effect": "Deny", "Action": [ "iot:Connect" ], "Resource": "*", "Condition": { "ForAllValues:StringEquals": { "iot:ConnectAttributes": [ "PersistentConnect" ] } } }, { "Effect": "Deny", "Action": [ "iot:Connect" ], "Resource": "*", "Condition": { "ForAllValues:StringEquals": { "iot:ConnectAttributes": [ "LastWill" ] } } }, { "Effect": "Deny", "Action": [ "iot:Connect" ], "Resource": "*", "Condition": { "ForAllValues:StringEquals": { "iot:ConnectAttributes": [] } } } ] }
下列政策不得具有 PersistentConnect，但可以具有 LastWill，而且不允許任何其他新功能：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Deny", "Action": [ "iot:Connect" ], "Resource": "*", "Condition": { "ForAnyValue:StringEquals": { "iot:ConnectAttributes": [ "PersistentConnect" ] } } }, { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": "arn:aws:iot:us-east-1:123456789012:client/client1", "Condition": { "ForAllValues:StringEquals": { "iot:ConnectAttributes": [ "LastWill" ] } } } ] }
下列政策只允許透過具有 LastWill 與主題 "my/lastwill/topicName" 的用戶端連接，而且只要其使用 LastWill 主題，就允許任何功能：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": "arn:aws:iot:us-east-1:123456789012:client/client1", "Condition": { "ArnEquals": { "iot:LastWillTopic": "arn:aws:iot:region:account-id:topic/my/lastwill/topicName" } } } ] }
下列政策僅允許使用特定的 LastWillTopic 進行全新連接，而且只要其使用 LastWillTopic，就允許任何功能：
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": "arn:aws:iot:us-east-1:123456789012:client/client1", "Condition": { "ArnEquals": { "iot:LastWillTopic": "arn:aws:iot:region:account-id:topic/my/lastwill/topicName" } } }, { "Effect": "Deny", "Action": [ "iot:Connect" ], "Resource": "*", "Condition": { "ForAnyValue:StringEquals": { "iot:ConnectAttributes": [ "PersistentConnect" ] } } } ] }
